Intelligent temperature and zero-point compensation algorithm, so that the instrument has better performance with good selectivity, avoiding interference from other gases to the detected gas
A variety of signal outputs, which can be easily accessed to industrial control systems such as PLC/DCS, and can also be used as a stand-alone control
Oversized dot matrix LCD display, support for Chinese and English interface
No open cover, electrochemical remote control operation, single person maintenance
Local alarm indication, all-in-one sound and light alarm (optional)
The instrument has overrange and antipolar protection to avoid the danger caused by human improper operation
Rich electrical interface for users to choose from
By ATSF6, UL, CSA and other certification, with international high-end quality
Product characteristics of sulfur hexafluoride gas leakage alarm device:
Imported electrochemical sensors have good anti-jamming properties and have a life of 8 years.
'Using advanced microprocessing technology, the response speed is fast, the measurement accuracy is high, the stability and repeatability are good.
The detection site has the function of on-site sound and light alarm, the gas concentration exceeds the standard instant alarm, is the safety of the operation of dangerous places.
4 field with backlit large-screen LCD display, visual display of gas concentration, type, unit, working status, etc.
5 independent gas chamber, replacement sensor does not need on-site calibration, sensor key parameters automatically recognized.
6 Full-scale range temperature digital automatic tracking compensation to ensure measurement accuracy.
