General Description
The Radiation Survey Meter and Surface Monitor’s small size, light weight, one hand operation, digital display, built in speaker, and large detector area make this a very useful monitor for surveying bench tops or checking hands and clothes for almost any radioactive contamination. It is also available with the mR/hour Scale, uSv/hscale Counts Per Minute Scale or Both Scalers (upon request). End Users: Fire Department, Ambulance, Police, First Responders and U.S Custom Personnel use for surveying people, cars, luggage, surface of room, etc.
Technical Description
The Radiation Survey Meter and Surface Monitor is a Small Digital Ratemeter with built in 2” diameter pancake tube and speaker. Reads out in mR/hr (or counts per minute). Thin window recessed and protected by sturdy grill. Additionally TBM-3SR-D has sliding methacrylate beta shield which also acts as additional protection for thin GM tube window. Instrument will see alpha, beta and gamma radiation. Anti-saturation circuit will not fall below full scale in high fields. Tested to 100R/h. It is also available with the mR/hour Scale, uSv/hscale Counts Per Minute Scale or Both Scalers (upon request).
