Improve your process temperature control with tighter calibration. The redesigned PIECAL 322 and 422 Thermocouple Calibrators are more accurate and repeatable than previous generations of test equipment including the most common calibration lab standards.  Flexible connections include screw terminals into isothermal brass blocks as well as miniature thermocouple plugs. A NIST traceable thermistor accurate to 0.05 degrees C monitors the temperature of the cold junction. Precision analog circuitry with an ultra-stable reference and low drift components combine for accurate, repeatable measurements. Accuracy is ±(0.008% of Reading +0.006 mV). For type J the accuracy ranges from 0.2° to 0.5°F (0.1 to 0.3°C).

PIE calibrators are one of the smallest and lightest calibrators available with a toolbox tough design.  Features include a backlit display for use in dark environments, protective rubber boot with built in stand, hands free carrying case and test leads. The easy to use double click menu system allows for quick setup, fast switching between thermocouple types/units and configuration of set point temperatures and step/ramp times. The PIE 322 sources and reads types J, T, E, K and millivolts.   The 422 sources and reads 14 thermocouple types and millivolts plus displays the cold junction temperature and mV value.  Both come with NIST certification and a 3 year warranty.
