Dose rate meter GRAETZ GammaTwin
Compact electronic dose rate meter with a “twin display” that shows dose rate and dose simultaneously.
Product highlights
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 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) (a meter with the measurand Hp(10) must be used to record the personal dose)
- 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
