Description
Overview
GAOTek radiation detection meter is a portable and practical means for identifying irradiated goods, and for helping remediate contamination and safety issues while minimally impacting operations.
Features
- Detects skin-dose (beta particle) and deep-dose (gamma) and X-ray radioactivity
- Requires no adjustments; simple two button process
- Provides promptly read, correct value through autoranging capability
- Easily visible inside truck trailers and other low-light situations with automated backlight
- Works dependably inside or outside thanks to sealed case
- Delivers more than one week of uninterrupted functioning with two 9 V alkaline batteries
- Proven in use by state and local governmental emergency response professionals, state inspectors, HAZMAT teams and nuclear power workers
- Measures both dose and dose-rate
- Valuable for contamination-detection, general radiation area metering, radiation-level monitoring, and hazardous materials assessment

| Automatic Features | Auto-zeroing, auto-ranging, and auto-backlight |
| Power Requirements | Two 9 V alkaline, 200 hours operation |
| Display LCD With Backlight | Analog: 100 element bar graph 2.5” (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 measurements are indicated on the display at all times. Digits are 0.25” (6.4 mm) high. Low battery and freeze indicators are also provided on the display |
| 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 |
