Measuring principle: GC-FID

The KVOC-1000 is used to measure methane (CH4), total non-methane hydrocarbons (NMHCs), benzene series (BTEX) and other volatile organic compounds（VOCs）in  accordance with the Gas Chromatography and hydrogen flame ionization detector (FID) technology.

Specification:

l Measuring gas: CH4, NMHC, BTEX, etc

l Detection limits: 0.8 mg/m3

l Repeatability: ≤2%

l Linearity error: no more than ±2% F.S.

l Zero drift:  ±3% (24h)

l Range drift:  ±3% (24h)

l Output and communication protocols: 4~20 mA, RS-232 / RS-485, Modbus RTU

l Size: 6U (19-inch standard chassis)

l Power supply: 220±22 VAC, 50±50 Hz

l Power consumption: ≤120 W

l Ambient temperature: 10~30 °C

Features:

l Using a special column combination, the sample is kept at 180 °C, peaking within 30s, no residue and high sensitivity

l With power-on self-test, gas off protection, power failure automatic restart and alarm and other functions to ensure the safety and stability of the system

l FID detector with automatic ignition function and wide range output, linear range 10^-7

l Automatic electronic flow control (EPC) technology to control carrier gas, air and hydrogen with high accuracy (0.01psi), good repeatability and reproducibility

l The core components have high reliability and long service life

Applications:

l On-line monitoring of fixed pollution source emissions, petrochemical, chemical, pharmaceutical, building materials, spraying, etc., and discharge outlets of large industrial and mining enterprises

l On-line monitoring of ambient air, factory boundary and ambient air

l Process monitoring
