Description
Overview
GAOTek negative ion tester is based on the most advanced GM ray energy detection technology and used to measure weak energy of radioactive rays from natural ores, ceramics, tourmaline, etc. Via long-term data experiment and accumulation, the energy of radioactive rays is converted into anion quantity by up-to-date computer technology. The extremely accurate measurement can be achieved by this method.
Technical Specifications
| Measurement mode | Model 1, Rapid measurement mode The detector measures for 10 seconds and then displays measurement value on LCD. Model 2, Standard measurement mode The detector measures for 20 seconds and then displays measurement value on LCD. Model 3, Accurate measurement mode The detector measures for 20 seconds for 8 times and then displays the average on LCD screen. It is mainly used to test low concentration and unstable anion products to obtain more accurate data. |
