AMETEK advanced signal calibrator

Oilfield Technology,

AMETEK Test & Calibration Instruments has released a new multi-signal calibrator, the JOFRA® ASC-400. This highly functional calibrator provides laboratory accuracy in an easy to use device that is compact enough to fit into a tool box or operate with one hand for easy field calibration.

The ASC-400 can be paired with new, improved advanced pressure modules, enabling it to become a true pressure calibrator with features such as leak test, switch test, scaling and online % error calculations. The new modules feature safe and easy to use crystal pressure fittings (CPF) for quick connect/disconnect. The modules are engineered for in-plant, field or laboratory use and are ready to use once they are plugged into ASC-400.

The ASC-400 features a high contrast colour display and an extremely user friendly interface. The instrument’s accuracy is designed to meet the demands of modern pressure sensors and transmitters. ASC-400 is capable of simultaneous read-back from device under test of mA, V, and pressure. When used with JOFRACAL calibration software, it can document as well. The device can additionally be used as a high accuracy thermometer through the use of resistant temperature detectors (RTDs) and CvD equations.

The calibrator features a full numerical keypad with cursor and function keys. Fuseless protection defends the instrument against voltage overloads up to 250 VAC, preventing the need for expensive repairs and recalibration. It can be carried in a handy soft case with a pocket for test leads and an opening in the top that provides easy access to test terminals.
