PRM 7000 Geiger Counter (Survey meter)

PRM 7000 Geiger Counter (Survey meter)

Handheld Beta, Gamma, X-Ray Geiger Counter and Nuclear Radiation Monitor

The compellingly priced PRM-7000 Geiger counter provides essential, professional-grade nuclear preparedness and radiation measurement during nuclear accidents, incidents or emergencies.

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 organizations, individuals, health physics professionals, educators, researchers, outdoor enthusiasts and rock collectors.

24/7 Monitoring Capability:

The instrument is designed to continuously collect measurements and statistics enabling complete environment assessment in order to support its nuclear preparedness mission objectives. This vital capability is typically 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).

The PRM-7000 Geiger counter 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.

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 supportting nuclear preparedness, provide over 3-years of life under normal conditions.

Made in the USA

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).
