The CL1201 is designed to provide very accurate and repeatable thermal calibration between 400°C and 1200°C for a wide variety of thermocouples and other temperature sensors in industries such as glass manufacture, power generation, automotive and material processing. This rugged, economically priced portable thermocouple dry block calibrator is supplied with a NIST traceable certificate. The unit provides excellent stabilities to within ±0.1°C and has display accuracy of better than ±3°C between 400 and 1200°C.
The CL1201 block calibrator utilizes a special heater design for optimum temperature uniformity and rapid heating rates. The heating system consists of heater elements embedded in lightweight vacuum formed ceramic fiber moldings which allows faster heating rates and extends the working life above other ceramic tube designs which have heater elements wrapped around a ceramic tube. An isothermal block assembly is machined from a special alloy giving excellent thermal conductivity and also resists high temperature oxidation.
This block is designed to optimize performance between sufficient mass for good stability and uniformity and to have a low enough mass to have rapid heating/cooling rates and short stabilization periods. RS232 communications is standard.
