Principle Introduction
| TesterMeter-MIX5007 work on the catalytic combustion principle. When the arm of electric bridge, which consists of a test element and a compensate element, meets the combustible gas, it will result the resistance of test element rising, At the same time, to change the output voltage of the bridge, the voltage variable is risen in direct proportion as the gas concentration, the compensate element play on the role of reference, and compensate of temperature and humidity. |
Features
