The HI766EX is a durable, coiled extension cable that adds 1 m (3.3’) to an existing cable on a thermocouple probe. At one end of the probe is a female thermocouple connector that allows connection with any of Hanna’s thermocouple probes or the HI766HD probe handle. At the other end of the cable is a male thermocouple connector that allows connection with a compatible thermocouple thermometer.
