The CL427 portable multifunction calibrator is a highly accurate and powerful system for testing, measuring, and calibrating, built into a compact portable instrument. The OMEGA™ CL427 portable multifunction calibrator is a versatile instrument designed to meet the needs of instrument engineers in laboratory and field work in a modern and practical way. Accurate, compact, rugged, and easy to use, it is an ideal solution for measuring and simulating: millivolts, volts, milliamps, frequency, sine wave, square wave, and triangle waveforms, as well as thermocouples.

The CL427 portable multifunction calibrator was developed using the most advanced microprocessor technology, providing high accuracy and powerful operational flexibility over an extended range. The unique internal automatic RJ compensation system enables the CL427 to provide accurate input and output readings across a temperature range of 0 to 50°C (32 to 122°F). In addition, external compensation is provided, allowing the user to fine-tune temperature output and measurement.

The CL427 model is designed for industrial environments such as factory floors, processing plants, service departments, and maintenance shops. Millivolts, volts, milliamps, and frequency can be measured or generated. Accuracy performance and stability allow you to calibrate field and control room instruments. Square wave pulses can be generated at frequencies from 0.3 Hz to 20 kHz. Pulse height is adjustable between 100 mV and 20 V. With this powerful capability, users can even test electromechanical equipment such as counters and relays. Simulating nonlinear temperature transmitters (Tx) allows users to quickly and easily check and calibrate 4 to 20 mA system input hardware and software. Users can set or operate temperatures associated with any available sensor in °C or °F, and input the appropriate milliamps into the system. The milliamps can be monitored simultaneously on the calibrator display.
