Digital Radioactivity Meter Medcom RADALERT 100X

• RADALERT 100X is a Geiger monitor for the measurement of alpha, beta, gamma and X radiation. It is intended for personal safety purposes. General purpose radiation detector, very easy to use, based on a Geiger-Müller detector with mica window, suitable for the measurement of alpha, beta, gamma, and X-ray radiation in environmental inspections, this meter is one of the most world's most popular Geiger monitors.
• The display can be toggled between dose rate and count rate modes; you can choose between units of µSv/hr and counts per second (CPS), or units of mR/hr and counts per minute (CPM).
• The equipment is equipped with a timer to be able to accumulate accounts within a predetermined period. The dose rate reading is updated every 3 seconds.
