two threshold levels for DE
РМ1401Р-01 and PM1401P-01B implement an improved search algorithm for detecting and localizing gamma radiation sources, as well as for measuring personal dose equivalent rate and personal dose equivalent.
Functions
- Search (detection and localization) of radioactive and nuclear materials
- Measurement of gamma radiation personal dose equivalent rate Ḣp(10) (DER) and personal dose equivalent Hp(10) (DE).
Features
- Highly sensitive combination of CsI(Tl) and plastic scintillator with DER and DE extended range
- In search mode instrument displays the gamma channel count rate in pulses per second
- Sound, visual and vibration alarms warn of set thresholds exceeding
- Instrument complies with the GOST P 51636-2000 detection requirements
- It is possible to record and store the instrument operation history in non-volatile memory
- PC connection via USB-C (PM1401P-01 and PM1401P-01B) and Bluetooth (PM1401P-01B)
- Long battery life
- IP67 sealed housing, small weight and size.
