These lightweight controllers have a carrying handle. They read temperature with a highly sensitive Type J thermocouple probe (sold separately) to turn heating equipment on or off at a specified temperature in critical process applications. Use the keypad to set the actuation point. All controllers are SPST (single pole, single throw). They have a control relay that turns one circuit from off to on (normally open). All come with a flat-pin connector for attaching a thermocouple.
