    RadEye SPRD-GN. The instrument must not be used in explosive atmosphere. The RadEye SPRD-GN is not intended to be used as a person- al dosimeter. No neutron dose rate or dose calculation is per- formed. Due to the high detector sensitivity the gamma dose rate measuring range of the RadEye SPRD-GN is limited to 250 µSv/h (25 mrem/h).

  • Page 15 The RadEye SPRD-GN enables measurement of detector pulse rates and energy compensated dose and dose rates. All menu functions described in 3.4 can be configured to be invisible. Thus the instrument can be configured to both, an extremely simple mode allowing just LCD-illumination and alarm ac- knowledgment to a very versatile mode for the more experi- enced user.
