Product Description
These are exceptionally clean CD V-700 meters (either Victoreen or Electro-Neutronics, our choice) that are incorporating a new and recently manufactured thin-end-windowed G-M tube (LND 723) encased in a new OCD-P-108 aluminum probe housing. (Sample of this thin-end-windowed G-M tube can be seen there in foreground of the photo.) They have been rigorously checked out, tested and recently calibrated at our licensed radiological calibration laboratory. Calibration sticker affixed to the side of the unit.
The CD V-700M is not calibrated to measure mR/hr. It is calibrated to measure alpha, beta, and gamma in counts per minute (cpm). The ranges are 0 to 300 cpm, 0 to 3,000 cpm and 0 to 30,000 cpm. To get mR/hr, which is only applicable to gamma radiation readings, you have to do some math: 2,400 cpm = 1 mR/hr. So the ranges are 0 to 0.125 mR/hr, 0 to 1.25 mR/hr and 0 to 12.5 mR/hr.
Also, very sensitive alpha and beta radiation detection at the probe window screened end that would not be detectable by standard CD V-700 G-M tube setup. Ideal for decontamination duties of checking people and the inspection of food & water for radiation contamination.
Unit includes headphones, carrying strap and the original manual. Requires 4 common D-Cell batteries.
