Calibration wafer

Sigma Sensors introduces its’ Lab Series RTD Temperature  Calibration  Wafer to address the challenges presented to semiconductor labs, fabs and metrology departments.

Sigma Sensors’ temperature calibration wafers are designed with the customer in mind: ease of use, accuracy, durability and global service mobility.

Our systems are based on the COWBOY TEMPERATURE WAFER®, a highly resilient sandwich-type construction composed of two layers of Si wafer with embedded ISO17025 calibrated (optional) PT100 4-wire thin-film temperature sensors.

The thermal characterization wafer is standard shatter-free  and has a survival rate of >50% on the 1M drop test. It comes with a stainless steel carrier for ease of handling and added protection during transport. 

Wafers can be purchased freestanding for use with any meter – or as a complete, self-contained system. All materials are cleanroom safe, non-particle shedding, no outgassing and temperature resistant from -60°C to +260°C.

Every temperature sensor wafer shipped meets the basic advertised factory specifications. As for upgrades, we do offer both traceable, non-accredited calibration as well as ISO17025:2017 accredited calibration.
