NRF31 Gamma / Neutron Personal Electronic Dosimeter

  • Model: NRF31

$1,300.00

Add to Cart:
The NRF31 Electronic Personal Dosimeter, EPD measures personal exposure of neutron and gamma radiation: dose and dose rate. The NRF31 features digital display and audible alarm. The user sets alarm threshholds for dose and dose rate by means of the NRZ software and reader.
