The Mustang® Heated Regulator (MHR) is designed to heat a gas sample to a customer specified temperature and pressure set point. Liquid condensation from a single-stage pressure reduction is prevented through a two-stage heating process.

The regulator body houses an electronically controlled thermistor and cartridge heater, precisely maintaining and measuring the gas sample. Through an innovative design comprised of a long, spiral flow path, the MHR eliminates the need of heating coils for efficient heat transfer and low maintenance.

The MHR assembly provides safe and reliable temperature control and pressure reduction essential to ensuring the performance of gas analyzers.
