Brief: This product is a brand-new concept instrument and adopts 4 kinds of patented technology, the measurement mechanism different from regular methods. This sensor is exchangeable with common gas sensor and the working power supply and signal transmissions are compatible. It especially for high gas mines.
Innovations:
1. Full-range continuous measurement of 0.00-100%CH4, without measurement suspension, thermal conductance component, resisting high and concentrated gas impact. Lower end of the range has extremely high measurement precision, and the higher end of the measurement range has sound linearity.
2. Special zero stabilization technology, with excellent stability and repeatability. 3-month maintenance-free time in the field, and the use and commissioning are easier than those of common sensor.
3. Zero, precision, alarm adjustments and etc of the instrument are executed by the infrared remote controller outside the machine, and unauthorized person is not allowed to enter to improve confidentiality. There is no adjustment hole on the instrument and the sealing is sound.
4. Long service life of the testing components, stable working, easy maintenance and convenient use.
5. Instrument is featured with highlighted sound and low power consumption, free of starting impact current , no current fluctuations under alarm condition, and is applicable to various kind of substation power supply.
6. The instrument has digital serial output function, which can effective inhibit "large numbers" interference.
