A、Full-range continuous measurement of 0.00-100%CH4, without measurement suspension, thermal conductance component, resisting high and concentrated methane impact. Lower end of the range has extremely high measurement precision, and the higher end of the measurement range has sound linearity.
B、Special zero stabilization technology with excellent stability and repeatability. 3-month maintenance-free time, and the use and commissioning are easier than those of common sensor.
C、Zero, precision, alarm adjustments etc. of the instrument are executed by the infrared remote controller outside the machine, and unauthorized person is not allowed to enter which improves the confidentiality. There is no adjustment hole on the instrument and the sealing is sound.
D、Long service life of the testing components, stable working, easy maintenance and convenient use.
F、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.
G、The instrument has digital serial output function, which can effective inhibit “False value” interference.
