General Details

Process gas analyzer for measurement of natural gas, biomethane, liquid gas, blast furnace gas, coke oven gas, different mixed gases and noncombustible gases.

Ominaisuudet

The measurement is performed continuously. The device has one measuring point. Calorific value, gross calorific value, Wobbe index and specific gravity are determined in dry gas. The device is equipped with one calibration inlet and can perform scheduled calibrations.
