GP-1003 GM Detector

GLE-1 Low Energy Gamma Scintillator

An excellent detector for Iodine-125 and other low energy gamma emitters. Also good for X-rays as well as beta emitters above 500 KeV. Encased in a special durable housing.

URSA-II

ERK-525 Emergency Response Kit Survey Meter

The ERK-525 is a complete, portable radiation monitoring system designed to measure a broad range of radioisotope contamination under field conditions. The system contains a state of the art, microprocessor based digital display meter that auto ranges and can detect most of the common alpha, beta & gamma radiation that is likely to be present in an emergency situation. The DSM-525 is a dual probe survey meter that measures contamination and dose levels from micro-R to 200 mR/hr levels of gamma isotopes (Based on 137-Cs calibration).

URSA-II

ERK-506 Digital Emergency Kit

The DSM-506 kit utilizes the new WB Johnson Survey/Scaler meter (DSM-506) to measure most alpha, beta, and gamma radiation & contamination fields from background to 2000mR/hr. An internal energy compensated GM detector, pancake & high sensitivity tissue equivalent scintillator are connected to the meter and can have dual (dose or cpm calibrations) that are switch selectable from the front panel.

DSM-525 Digital Radiation Survey Meter w/ Dual Detector

DSM-525 Digital Radiation Survey Meter w/ Dual Detector

The DSM-525 is the most functional survey instrument on the market with its dual probe capability. This dual connection capability allows users the luxury of multiple level measurements with as many as four different probes calibrated to each measurement type. No more retracking to the instrument case to switch probes.

DSM-506 Digital Radiation Survey Meter

DSM-506 Digital Radiation Survey Meter w/ Internal/External Detectors

The operation of the DSM-506 provides users the ease of an internal detector with the additional probe capability for those specific measurement needs. This feature, with its easy to read display, digital electronics and rugged design make the 506 a perfect instrument for all applications.

DSM-503 Digital Radiation Meter

DSM-503 Digital Radiation Meter w/ Internal Detector

The DSM-503 Survey meter is the perfect mix of rugged and dependable for use in a variety of environments. With it's internal detector, this instrument is designed to fit the perfect application for general users of radiation measurement and monitoring. The internal energy compensated gm detector makes this instrument a perfect fit for general users of radiological instruments.

GP-1003 GM Detector

ASP-2(A) High Frequency Alpha Detector

Excellent ALPHA detector with ZERO BACKGROUND in gamma fields up to 1 R/hr. Low density window of 5 mg/cm2 enables the high efficiency detection (40+% 2Pi) of alpha down to 3 MeV. Mounted in shock resistant metal housing.

GP-1003 GM Detector

AM-805 Foot Monitor

Three pancake GM detectors configured in a sturdy angled foot rest to make it easy to scan shoes and boots for contamination. Includes a mounted spindle on which to place "cling" wrap to cover the detector area and prevent dirt and contamination from falling onto the detectors. Works with any Johnson meter, but especially designed for the RML-200 Lab Counter-top Alarming Ratemeter.

AM-801 Portable Portal Monitor

AM-801 Portable Portal Monitor

This Portable Portal monitor assembles simply in under five minutes. It comes with Voice Operational Commands, Full Color Touch Sensitive graphics panel, and Auto Cal for Maximum Sensitivity.
