Temperature Regulators

All modules require an external temperature regulator/ controller. Designed for remote location outside the corrosive atmosphere in the fume hood. They are available in 110V and 208-240V versions depending on the power circuits available in your laboratory with either a basic timer/single setpoint or multiple temperature program capability.
