Technical Associates TBM-3 Contamination Meter, Geiger Counter. Good used condition. Convenient little meter uses a single standard 9-Volt battery and checks Alpha, Beta and Gamma radiation. A nice feature is that it has a swing-away handle and a built-in speaker, so no head phones are required. I no longer have a calibrated check source, so for demonstration that the meter works, I used a picture of it registering the radiation from a piece of old orange “Fiestaware”. (For those who do not know- red/orange Fiestaware made up to about 1943 used uranium oxide as a pigment. Fiestaware saucer is NOT included in the sale.) Factory specs are reproduced below: Model TBM-3 Survey Meter Internal Pancake Geiger Mueller Detector For Alpha, Beta, and Gamma General Purpose Survey This small survey meter features an internal two inch diameter "pancake" Geiger Mueller tube and speaker. The analog display is a dual scale in counts per minute (cpm) and mR/h. The thin window of the G-M tube is located on the bottom of the survey meter. it is recessed and protected by sturdy grill. The Instrument will detect alpha, beta, and gamma radiation. The anti-saturation circuit will not fall below full scale high fields. The instrument is tested to100 R/h. This light weight, compact survey meter is useful for surveying bench tops or frisking the body, and clothes for almost any radioactive contamination. This model is recommended for emergency response. U.S. Customs personnel find this type of survey meter useful for surveying people, vehicles, and luggage.
