Contador Geiger VOLTCRAFT RM-400 detetor de radiação alfa beta gama raios X com alarme acústico, software, registador de dados VC-12822170

Detect alpha, beta, gamma and X-ray radiation with a sensitivity of 80 CPM/µSv/h and a dose rate range from 0.01 to 1000 µSv/h. The VOLTCRAFT RM-400 Geiger counter provides precise measurements and immediate acoustic and visual alarms when thresholds are exceeded.

Overview

The RM-400 is a portable radiation detector built around a halogen-filled Geiger-Müller tube. It measures dose rate in µSv/h, cumulative dose in mSv, and count rates in CPM and CPS. The large backlit LCD shows readings clearly in any light, and the adjustable alarm threshold warns you of elevated radiation levels. With a data logger capacity of 32,000 data points and USB connectivity, you can record and analyse measurements on a PC using the included Windows-compatible software.
