Electronic Personal Dosemeter GRAETZ ED 150

with dose rate indication and alarm functions ED150

PTB-approved dosemeter for measuring gamma and X-rays for the measuring size H_x (personal dose equivalent)
detector: energy compensated GM-tube
digital indication of measured values on LC-display
dose indication range with floating decimal point
dose rate indication upon keystroke
high measuring accuracy
reliable and safe measurement of radiation in front of the user's body (detection of a solid angle of 180°)
especially shaped display ensures optimum reading of measured values
switchable, acoustic single-pulse indication
4 dose alarm thresholds
4 dose rate alarm thresholds
menu-driven operator guidance
optical interface
storage of dose value and set parameters also during battery change
high reliability by continuous self control and test function
small and handy metallized housing made of high impact-proof plastic, easy to decontaminate
watertight up a a submersion depth of 0,5 m acc. to protection class IP67
EMC-proof
power supply by 3 pcs. 1,5V Lady cells LR1
operating life approx. 1 year with one battery set at ambient background radiaiton
when used together with the readout unit EDAG 02 also usable as system dosemeter
