Description

The CA300 Series is a high accuracy source and measure portable handheld calibrator used to inspect and maintain the accuracy of control devices such as temperature controllers, temperature transmitters, temperature sensors and other process devices which are used in process plants, industry machinery, and manufacturing. Available in 3 models, the CA310, CA320, and CA330 provide an ergonomic and friendly user-interface making it easy to use.

The CA320 is a dedicated process calibrator which is capable in performing inspections and calibrations of thermocouples. It is three times more accurate than the present CA12E with a high accuracy of ±0.5℃ error which is top class as a handy type to source thermocouple output and measure output of sensors. It not only corresponds to JIS standard and IEC standard thermocouples, but corresponds to ASTM standard and GOST-R standard too. It corresponds to inspection and calibration with the summary of 16 types of thermocouples following the standards.
