| Radiation detected | Beta | > 1 MeV |
| Gamma | > 25 keV |
| Operating ranges, response time | 0 μR/h to 500 μR/h (5 sec) |
| 0 mR/h to 5 mR/h (2 sec) |
| 0 mR/h to 50 mR/h (1.8 sec) |
| 0 mR/h to 500 mR/h (1.8 sec) |
| 0 R/h to 5 R/h (1.8 sec) |
| Accuracy | Within 10% of readings between 10% and 100% of full scale indication on any range, exclusive of energy response |
| Detector | Chamber | 230 CC Pressurized ionization chamber to 8 atmospheres or 125 psi |
| Controls | ON/OFF and MODE |
| Automatic features | Auto-zeroing, auto-ranging, and auto-backlight |
| Warm-up time | Less than one minute for initial operation when the instrument is in temperature equilibrium with the surrounding area, typical. (About four minutes for readings if less than 20 μR/h in a 10 μR/h or less background) |
| Display LCD analog/digital with backlight | Analog | 100 element bar graph 6.4 cm long. Bar graph is divided into 5 major segments, each labeled with the appropriate value for the range of the instrument |
| Digital | 2.5 digit display is followed by a significant zero digit depending on the operating range of the instrument. The units of measurement are indicated on the display at all times. Digits are 6.4 mm (0.25 in) high. Low battery and freeze indicators are also provided on the display |
| Modes | Integrate mode | Operates continuously 30 seconds after the instrument has been turned on. Integration is performed even if the instrument is displaying in mR/h or R/h |
| Freeze mode | Will place a tick mark on the bar graph display to hold on the peak displayed value. The unit will continue to read and display current radiation values |
| Environmental | Temperature range | -20 °C to 50 °C (-4 °F to 122 °F) |
| Relative humidity | 0 % to 100 % |
| Geotropism | Negligible |
| Typical energy dependence | Nitrogen gamma rays are 110% to 120% of indicated readings as determined at the University of Lowell |
