characteristic

Professional trace gas measurement less than 5ppm

Supports self-calibration by ambient air

use acoustic signal for calculating concentration, less interference

integrated infrared H2O detector, effective prevent humidity interference

integrates pump and automatic valve control up to 3 sample points

Equipped with an active carbon filter to prevent air pollution

Sampling tube are stainless steel pipe, near to sample point each line has inline dust filter with exchangeable filter-eleme

Effective prevent humidity interference : Integrated infra-red H2O detector for

real-time calculation

Effective prevent Temp. interference: Photoacoustic module heated to 50℃

Effective prevent other gas interference: Calculated with acoustic signal to gas concentration
