PRM-7000 Handheld Beta, Gamma, X-Ray Geiger Counter and Nuclear Radiation Monitor
The compellingly priced PRM-7000 provides essential nuclear radiation awareness during a nuclear accident, incident or emergency
The PRM-7000 is built upon the same long battery life, high quality, made in the US, platform as the PRM-8000 and PRM-9000, which have been the choice of governments, organizations and individuals around the world.
The instrument is designed to similar specifications as devices used by firefighters, HAZMAT teams, paramedics and other first responders to address the radiation hazards they face.
Unlike other instruments in this price range, the PRM-7000 can be calibrated to the official international standards of accuracy required for regulatory work. An actual NIST-traceable calibration report example can be reviewed here.
Not The Best For Testing Food
Note, the PRM-7000 is not the best choice for testing food – please consider the PRM-9000
The PRM-9000 is 7.7 times more sensitive than the PRM-7000 to gamma nuclear radiation and is best for detecting lower levels of contamination in items quickly. 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.
Mazur Instruments uses only genuine detector tubes, made in the US, by LND in all of its products and does not rely on imported, cloned or “knock-off” detector tubes present in some lower priced products.
Accurate, reliable, made in the USA, the PRM-7000 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 6-years under normal conditions from a single, readily available, 9-volt lithium battery that is user-installable without soldering.
The supplied standard alkaline 9-volt batteries, available virtually everywhere, provide over 3-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-7000 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).
