Dose Rate Monitor GammaTwin
mobile dose rate monitor to measure gamma and x- radiation / 
for surrounding equivalent dose rate H*(10) and surrounding equivalent dose H*(10) / 
Simple handling / digital value indication on LCD

The dose rate monitor GammaTwin is a device that measures gamma - and x-rays. Its simple handling and its robust design with an aluminum enclosure qualify the dose rate monitor as a valuable device. The dose rate monitor GammaTwin is a compact and calibratable, portable measuring instrument, which indicates the measured values digitally at a LC display equipped with background lights.  As a detector of the dose rate monitor there is an energy-compensated Geiger counter installed. The dose rate monitor is adjusted by the manufacturer with four thresholds for the dose and dose rate, setting off a warning, before sent to customers. The non fluctuant data storage of the dose rate monitor saves automatically and continuously the measured values, even over battery changes. 
While operating with the dose rate monitor, the user does not need to be cautious regarding a special environment, due to its aluminum enclosure that is in addition IP54 protected. Thus the dose rate monitor has no troubles endure smaller amounts of splash water. In case that you should have more questions regarding the dose rate monitor GammaTwin, please read the following technical data, use our contact form or call us: UK customers +44(0) 23 809 870 30 / US customers +1-410-387-7703. Our technicians and engineers will gladly advise you regarding the dose rate meters or all other products in the field of Control Systems, Laboratory Equipment, Measuring Instruments or Scales and Balances of PCE Instruments Ltd.
