SURVEYMETER MONITOR 4

Pocket-sized monitor with meter, LED count light, and beeper • Monitors alpha, beta, gamma, and x-ray radiation • Dual-scale analog meter ( CPM and mR/ hr) • Operating range: 0-50 mR/ hr, 0-50, 000 cpm • Multiplier selections: x1, x10, x100 • Red LED flashes with counts • Audible beep indicates rising radiation level • Operates up to 2, 000 hours on 9V battery • Weighs less than 9 ounces ( including battery) The Monitor 4 Survey Meter is lightweight, ergonomically designed and includes its own carrying case. Used to measure alpha, beta, gamma and x-ray radiation, it provides extremely accurate results with both audible and visual indication. The easy-to-read scale features three ranges for maximum sensitivity and runs up to 2, 000 hours on a 9V battery.
