Dose rate alarm unit GRAETZ GammaTest C
The dose rate alarm unit GRAETZ GammaTest C has been designed for personal radiation protection when dealing with ionizing radiation. This dose rate warning device has four preset warning thresholds that trigger a visual and audible alarm when exceeded. Below the respective warning threshold, the optical single pulse display signals the increase or decrease of the dose rate by changing the flashing frequency. Easy handling and robust design in pocket format make the GRAETZ GammaTest C a reliable radiation measuring instrument for a wide range of applications.

Product Highlights
Robust construction in pocket format
Four selectable dose rate warning thresholds for individual radiation measurements
Single pulse display for increase or decrease of dose rate
Integrated test function for more safety in operation
Dust and splash water protection (protection class IP54)
- The GammaTest C is a lightweight, rugged, battery-operated dose rate warning device for radiation protection for the detection of gamma and X-ray radiation in the measurand Ḣ*(10) ambient dose equivalent rate.
- The GammaTest C has four warning thresholds that trigger audible and visual alarms when exceeded
- Below the warning threshold, the GammaTest C indicates readiness for operation via the red LED and signals increases or decreases in dose rate as an optical single-pulse display by changing the flashing frequency
- The dose rate warning threshold 25 µSv/h is used in fire department operations to determine the limit of a danger zone according to FwDV 500
- The dose rate warning threshold 40 µSv/h is required in the field of non-destructive testing (NDT) for radiographic testing: For mobile handling, the local dose rate must not be higher than 40 µSv/h
- The splash-proof, anodized aluminum housing provides shielding against electromagnetic influences
- Operating time with one set of batteries at ambient radiation approx. 250 hours in 24 h operation
