Accurate Operation
- Factory-calibrated using a pulse generator
- Standard ±15% of the full scale relative to Cesium-137
- Results in milliroentgens/hour and counts/minute (cpm) in 3 periods
- Anti-saturation circuit up to a value equivalent to 100 times the maximum reading in the greatest interval
Easy to Use
- Results by graduated scale, flashing LED and acoustic signal
- Operates up to 2000 hours on one set of batteries
- Detects α, ß, γ and x-rays
- Choice of 3 measurement ranges
