Although it employs the same case as the Model 10th and Model 121 Geiger counters, the Precision Radiation Instruments (PRI) Model 123, known as the "Squealer," is not a radiation detector. It is a speaker - amplifier that serves as an external audio output for the detector that it happens to be coupled to. Has connectors for headphones, but did not come with a built in speaker. The Squealer gives the user the option of listening to the audio output of a PRI instrument without having to use headphones. Dimensions: 3.75" x 4.5" x 7.5" Controls: Colume, tone Batteries: Two 1.5 volt "D" cells, one 45 volt, one 67.5 volt and one 1.5 volt (?) Pen light batteries.
Condition:
Used: An item that has been used previously. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a floor model or store return that has been used. See the seller’s listing for full details and description of any imperfections. ...
