Overview
Enviro Test Construct Geiger counter radiation detector counting instrument designed to detect the intensity of ionizing radiation (a particles, particles, y rays, and x rays), using an inflatable tube or chamber as a probe when a voltage applied to the probe reaches a certain range, for every pair of ions produced by the ionization of the Ray in the tube, an electro pulse of the same size can be amplified and recorded by a connected electronic device, thus measuring the number of ray per unit time.
