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 CA310 is a dedicated process calibrator which is capable in performing a control loop check and inspection of devices. It has three times higher accuracy of ±0.015% rdg.* to source and measure mA and voltage. It can be used under HART or BRAIN communication with 250 ohm resistance embedded. *“rdg.” is an abbreviation of reading which means the error rate to the measurement value.
