

Large backlit LC display with a so-called “twin display”: Simultaneous display of dose rate and dose



Acoustic warning signal when warning thresholds are exceeded



Intuitive operation



Compact and robust design, dust and splash water protection (protection class IP54)

Small, handy, calibratable dose rate meter for measuring gamma and X-ray radiation for the measurands Ḣ*(10) ambient dose equivalent rate and ambient dose equivalent H*(10) (to record the personal dose, a meter with the measurand Hp(10) must be used).
Detector: Energy-compensated Geiger-Müller counter tube
Large, digital measured value display on LC display (backlit)
Optional simultaneous or separate dose and dose rate display, additional analog display of dose rate as logarithmic bar display
4 factory preset warning thresholds for dose and dose rate; customer-speciﬁc modification on request.
Switchable acoustic single pulse detection
Automatic continuous storage of the dose in a non ﬂüchtiger memory.
Storage of the dose and the set parameters even when the battery is changed
Constant self-monitoring
Designed for rough use, aluminum housing, protection class IP54 (splash-proof)
Menu-driven operator guidance
Durable nylon belt pouch is included in delivery

Optional:
Test device PV-GTw and test source PS 9 for calibration validity extension to 6 years
