Electronic personal dosimeters of PM1610 series provide measurement of dose equivalent (DE) and dose equivalent rate (DER) of continuous and pulsed X-ray and gamma radiation in the energy range from 20 keV to 10 MeV, as well as time of dose accumulation. Instruments have audible, visual and vibration alarms warn the user when preset dose/dose rate threshold levels are exceeded. Shockproof rubberized case and  LCD with fluorescent backlight allows operation in harsh environment. Dosimeters are compact and easy to use, have long life built-in rechargeable batt
