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 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.
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.
