EXPEC 3050

VOCs analyzer based on FID detector principle is an industry recognized class of instruments for the detection of VOCs, related standards are: GB37822-2019 "Non-organized emission control Standard for Volatile organic compounds", HJ38-2017 "Determination of total hydrocarbon, methane and non-methane total hydrocarbon in the exhaust gas of fixed pollution sources gas chromatography", HJ1012 2018 "environmental air and exhaust gas total hydrocarbon, methane and non-methane total hydrocarbon portable monitor technical requirements and detection methods", HJ 1013-2018 "Technical requirements and testing Method for continuous monitoring system of Total non-methylane hydrocarbon in the exhaust gas of Fixed Pollution Sources", etc.


Whole machine explosion-proof design

The circuit of the whole machine adopts intrinsic safety explosion-proof design, and the core FID
detector module adopts flameproof design.

High accuracy

FID detector,consistent with online VOCs system, provides an accuracy unmatched by handheld PID.

Easy to carry

Light weight, the weight of the host is less than 2 kg (portable non-methane total hydrocarbon analyzer is generally 10-20kg). Small size, easy to carry

Easy to operate

It only takes 2 steps to test, and users can view test data, calibrate and set parameters through the panel.

High reliability

The technical route and spectrum of large-scale production of EXPEC 3100 are in the same line, reliability is trustworthy.

Transportation Safety

The application of the hydrogen storage alloy enables the instrument to be transported or mailed safely.

Perfect after-sale

The perfect after-sales service system of EXPEC Technology provides customers with comprehensive after-sales engineering services.
