Argon Concentration Meter Measuring Range 0-100%VOl industrial gas
leak detector with 4-20mA&Rs485 signal output
Product Brief Introduction:
Nitrogen detector is especially suitable for detecting high-purity
nitrogen and nitrogen concentration in various industrial
environments. The instrument adopts imported nitrogen sensor and
microcontroller technology, which has the advantages of stable
signal, high precision, good repeatability, etc. Explosion-proof
connection mode is suitable for all kinds of dangerous places.The
instrument is compatible with various control alarm, PLC, DCS and
other control systems, and can realize remote monitoring, remote
control, remote alarm, computer data storage, analysis and other
functions.
