The "Electro-Count"
survey meter was built by Electronic Counter Laboratories Inc. of Hollywood, California. It was primarily intended for uranium
prospecting. Detector: one Victoreen 1B85 GM tube Audio: headphone jack Range: 0 - 0.2, 0 - 2.0 and 0 - 20.0 mR/hr. Size: 5" x 8" x 4.5" Batteries: as a guess, it would appear that it might have used one 22.5 volt (e.g., Eveready 412), one 67.5 volt (e.g., Eveready 467), and two1.5 volt D cells Kindly donated by Chuck Abraham |
