All models are factory-calibrated to pulse generator and can be calibrated to ANSI standards by any certified lab. Anti-saturation circuit is good to at least 100 times the maximum reading in the highest range. No special probes are required. Ergonomic design decreases worker’s fatigue over long periods of use. Meters operate on one 9 V battery (sold separately).

General-Purpose Detectors are available with uncompensated halogen-quenched sensors for measuring alpha, beta, gamma, and X-ray radiation; select meters with energy-compensated sensors for increased sensitivity to gamma and X-ray radiation.
