Features

Filter element can be easily disassembled and replaced.

Adopt single-flange design with high integration and easy installation.

With high-temperature flowmeter, user can observe flow during equipment operation.

Sampling measurement is free from interference of pipeline deformation, high dust and other working condition change, with strong adaptability.

The whole gas path is equipped with high-temperature heat tracing and regular auto purge to prevent dust and crystal like salt from blocking the equipment, less maintenance.

Application

        Applied in online gas monitoring occasions including denitrification device, boiler flue and exhaust detection, etc.
