Keco Model 50 Process H2S Gas Analyzer

Keco Model 50 Process is a microprocessor-controlled analyzer that measures only H2S by the ASTM-approved tape method. The measurement range extends from single-digit ppb to 500 ppm. It is used for process control, air quality and product quality in areas such as biogas, chemicals, gas processing, landfills, natural gas pipelines and wastewater treatment.

• Small, light body (10 x 12 x 6 inches, about 10 lb).
• Automatic zero requiring no zero gas; calibration rarely needed.
• Fault diagnostics and design suitable for Class 1 Division 2 areas.
• Options include alarm relay, RS-232/RS-485 Modbus, isolated 4-20 mA and data logger.
• A pipeline sample probe, liquid separator sample system, H2S scrubber and cabinet heater can be added.

For a quotation, specify sample pressure and temperature, gas composition, presence of free liquid, line length, hazardous area class and supply voltage.

Tetra configures Model 50 with a sample probe and liquid separator according to the plant's gas composition and carries out pole or shelter mounting. Tape and calibration consumables are replaced on site during service visits.
