PRM-9000 Geiger Counter - Nuclear Radiation Contamination Detector & Monitor

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.

 


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.



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).
