Cosa Xentaur

Xentaur’s Dew Point Meter, Model LPDT, is the world’s smallest loop powered (2-wire) dew point transmitter with a display.

Xentaur’s Dew Point Meter, Model HDT, is a rugged and unique loop powered dew point meter capable of both gas and liquid hydrocarbon phase measurements.

The Xentaur digital dew point transmitters are designed as compact, simple and reliable instruments, which will continually monitor air dryer performance, compressed air quality and dry gas moisture, from ambient dew point levels to as low as -100ºC (-148ºF) up to +20ºC (+68ºF).

XDT in explosion proof enclosure, UL approved for use in Hazardous Locations Class I Division 1 Groups B, C & D;

The portable dew point meter, model XPDM, is a battery operated, hand-held, hygrometer, designed for applications where quick and accurate dew point measurements have to be made.

The HGC 303 is the world’s smallest gas chromatograph for C6+ analysis of Natural Gas. It digitally publishes 20 derived parameters, such as Calorific Value, Wobbe Index, Specific Gravity, Compressibility, Ratio of Heats, etc.

Wobbe Index / Calorific Value / CARI

The COSA 9610™ is one of the latest instruments from COSA Xentaur for measuring Wobbe Index, BTU/Heating Value and CARI (Combustion Air Requirement Index).

Wobbe Index / Calorific Value / CARI


The Cosa 9700 is a fast response calorimeter for the on-line monitoring of Wobbe Index (WI), Combustion Air Requirement Index (CARI) and Heating Value (HV). The COSA 9700 is based on the Residual Oxygen Method (ROM), thus avoiding the use of a flame.

The COSA 707 is a hand held multigas analyzer for industrial and combustion processes.
