Geiger Counter
I am the EXCLUSIVE and AUTHORIZED reseller for Mazur Instruments
on eBay. Your purchase will receive the exact same warranty and
excellent customer service as the manufacturer! Please be
cautious if you are considering purchasing a "used"  or
new unit from other sellers as they are not authorized.
Please do not think you will spend 0 or 9
on one of the other units being sold on ebay
and get the same functions! The less expensive SOEKS
geiger counters measure ONLY gamma radiation.
Mazur Instruments units measure alpha, beta,
gamma and x-ray radiation!

Nuclear Radiation Contamination Detector and Monitor -
(Case included! Cable in photo not included.)
The PRM-9000 is one of the finest units you can
purchase because of its quality and accuracy!
- 350% more sensitive than the PRM-8000 -
The PRM-9000 is 3.5 times (350%) more sensitive than the PRM-8000.
It can sense smaller amounts of radioactive contamination than the PRM-8000.
The PRM-8000 will quickly tell the user that an area is safe, but the 9000
is more sensitive and better suited to check for trace contamination
on surfaces, on items, on people, etc. - Vince Mazur
PRM-8000 or PRM-9000 What Is the Difference?
The PRM-9000 is 3.5 times more sensitive to nuclear radiation, but cannot be taken
outside above 10,000 feet without risking damaging the Geiger tube - rendering the
device inoperative. Flying or shipment by commercial air is fine. The PRM-8000 is lighter
and more rugged. The PRM-9000 is best for detecting lower levels of contamination in
items quickly. The PRM-8000 is also able to detect lower levels of contamination in
items, but requires more time (using the timed measurement functions). No Geiger
counter is exceptional for detecting trace contamination in food, but the PRM-9000,
with its pancake tube is the better of the two for scanning food.

The PRM-9000 includes the same two-inch (50.8 mm) pancake Geiger detector tube that is the gold-standard for surveying areas for potentially harmful ionizing radiation levels and for detecting radioactive contamination of packages, items, equipment and people.
The instrument is suitable for regulatory inspections, and for the detection, measurement and monitoring of broad spectrum, low energy radionuclides, including Naturally Occurring Radioactive Material (NORM).
The detection sensitivity combined with the feature-set outlined below results in one of the most compelling price/performance values in the industry.
Accurate, reliable, made in the USA, the PRM-9000 Geiger counter is an ideal solution for individuals, health physics professionals, educators, researchers, outdoor enthusiasts and rock collectors.
Unique Monitoring Capability
The instrument is designed to continuously collect measurements and statistics enabling complete environment assessment. This vital capability is not available on similarly priced products.
Using only one key, users can scroll through several screens that display present, average, maximum and minimum measurements in uR/hr, mR/hr, uSv/hr, Counts per Second (CPS) or Counts per Minute (CPM).
This nuclear detector not only records the maximum radiation measured, but also displays the time and date at which the maximum reading occurred. Conventional Geiger counters require the user to be looking at the radiation meter to capture such events.
Supports English and Japanese
The two-line, alphanumeric display supports both English and Japanese languages promoting ease-of-use and concise measurement. The display is backlit to support low-light conditions.
Industry Leading Battery Life
The battery life of this radiation detector and monitor is over 4 1/2 years under normal conditions from a single, readily available, 9-volt lithium battery that is user-installable without soldering.
Standard alkaline 9-volt batteries, available virtually everywhere, provide over 2-years of life under normal conditions.
Data Logging and USB Connectivity
With over 100K bytes of internal data logging memory included, this Geiger counter can autonomously (without the need for a PC) store up to 91,466 minutes or hours of time-stamped measurements. These measurements can then be uploaded later to a PC in CSV format for analysis.
A user-settable dose rate alarm sounds an audible alert when the measured radiation level exceeds that of the alarm level setting.
Designed by Mazur Instruments and manufactured in the USA, the PRM-9000 Geiger counter and nuclear radiation monitor includes abundant I/O options including support for headphones, external speakers, external power and USB data exchange (Requires Optional 3.5mm to USB Adapter Cable).

Here is Vince Mazur's responses when asked about comparing the PRM-9000
to another popular selling unit on the market, and about an external probe:
Vince Mazur's response about comparing this new PRM-9000 to a popular selling competitor:
Yes, it is better than the xxxxxxxx - by a wide margin. The PRM-9000 was designed to give users a more attractive choice over the xxxxxxx.
1) Battery life is about 10X better than the xxxxxxxx with a standard 9V battery. 20X with a lithium 9V cell.
2) You must be looking at the xxxxxxxxx to see what it is reading, our unit is always recording measurements, keeps track of the average, keeps track of the maximum, tells you when the maximum occurs. This is essential for 24/7 monitoring of one's environment. The xxxxxxxx does not provide any of these statistics.
3) The xxxxxxx supports timed measurements, however the user must convert results manually with a calculator to establish Average mR/hr (or uSv/hr). The PRM-9000 timed measurements read out directly in mR/hr (or uSv/hr).
4) Our unit reads to 125 mR/hr, The xxxxxxxx goes only to 100 mR/hr.
5) With an optional cable, our unit can connect to a PC or Mac for data logging, or uploading internal measurement logs - the xxxxxxxx does not support any interface to a PC or Mac.
6) Our unit uses text menus and a simple interface, the xxxxxxxx uses a complex series of button presses for altering its settings.
7) The face of the instrument has no seams and it is water resistant. The xxxxxxxxx is riddled with openings on the face where water can go through and disrupt the electronics.
8) The construction of the PRM is superior - Anyone comparing and holding the two units side-by-side will agree.
9) Our unit has a backlit LCD, which comes in handy if power is out. You need a flashlight to read the display on the xxxxxxxx because it has no backlight.
10) The PRM series also included data logging, the xxxxxxx and other xxxxxxxx products do not.
11) The xxxxxxxx uses the same LND-7317 Geiger Tube as the PRM-9000.
There really is no comparison, but the xxxxxxx has been around for quite some time.
Here's a quote form a PhD in Physics from Duke who performs calibrations on a variety of instruments:
"I
had a couple xxxxxxxxxx in the lab and I like the overall design of the new Mazur meter better. You all did a very nice job. Congratulations."
External Probe?
The thing about the external probe is that you have the cable dangling and generally, you must use two hands to take a measurement.  So your moving the probe looking back and forth between where the probe is and what the reading is saying - its awkward. The cable also injects another potential point of failure. The cables are generally not standard and can not be purchased at a Target or Radio Shack. Damage the cable and the unit is useless,  So we see the external probe impacting overall reliability of the all-in-one design.
Regarding contamination: the most expensive part of a Geiger counter is the Geiger Mueller tube, and if the probe gets contaminated, sure you can replace it, but at considerable cost.  Also, much of the electronics is actually put inside of many of today's external probes, elevating cost of the external probe.
Also, the storage requirement is better for a completely self contained unit. Our units come with a carrying case that can be worn on a belt. External probe models are relatively bulky. Our units can fit into most glove boxes or center consoles of cars.
Another subtlety: The all-in-one unit also don't call as much attention in public places. You'd really be noticed using an external probe model to scan merchandise at a home store. With the PRM you basically hold the meter in one hand and can quickly scan.
There are situations where one would want to use the wand of the external probe to get into small areas and such, and for that the probe is ideal, but in our opinion it brings more liabilities then assets for most uses.
Hope this helps, Vince
Comparison to the Soeks Geiger Counter
The Soeks unit relies on rechargeable batteries and the battery life is considerably less than our PRM units - only 10 hours before recharge. Compare the constant monitoring battery life of the PRM-9000 at 2.33 years or the PRM-8000 at 3.2 years!
The Soeks unit is smaller and has a larger display, but the small size requires small batteries and the color display takes more power. Combined, this results in poor battery life and the requirement to have AC power readily available 24/7 for any long term monitoring.
However, a crtical draw back of this unit is that it only detects gamma radiation and not alpha and beta. While they do not provide specifics on their detector, the pancake detector of the PRM-9000 is far superior in sensitivity. The detector in the PRM-8000 is far superior as well.
