Sarasota SG901 (formerly SG900) Specific Gravity Analyzer

Measure the density, pressure and temperature of dry and wet gases with the Thermo Scientific™ Sarasota SG901 (formerly SG900) Specific Gravity Analyzer, a self-contained bypass sample conditioner. The compact model features fast response and continuous, high accuracy measurements to 0.2% of reading, making it an ideal choice for a variety of applications.

The rapid response of the SG901 ensures effective burner, furnace and flare gas monitoring and control. It is recommended in applications where specific gravity (SG) or molecular weight (MW) can be used to infer density elsewhere in the plant and where the gas is dirty or wet and requires filtering prior to the measurement. The SG901 is available in three configurations: a basic system, a dry gas system and a wet gas system. It comprises of a Thermo Scientific™ FD900 gas density assembly, temperature element and flow control valve. Built to endure harsh environments, the SG901 requires minimal maintenance and on-site calibration is not necessary.
