The 12-channel analogue Chino temperature recorder has been selected as ideal for the rigours of site heat treatment. The recorder design is potentiometric, self-compensating for ambient temperature and operates over the temperature range 0-1200°C

The recorder is housed within a rugged steel casing and is fitted with rear polarised socket connections for the widely used Type K thermocouple to compensating lead connections, to prevent reading errors. A flying lead is also fitted to the rear of the case to for the 110V AC input power from the heat treatment transformer.
