Omega CL543B Multi-Function Temperature Calibrator

Omega CL543B Temperature Calibrator (RTD & TC)

The Omega CL543B is a premier handheld calibration tool designed for instrumentation professionals who require versatility without compromising accuracy. As a dual-function device, it serves as both a high-precision simulator (Source) and a digital thermometer (Measure) for virtually all standard temperature sensors used in the industry.

Capable of handling 14 thermocouple types and 12 RTD curves, the CL543B is an all-in-one solution for calibrating transmitters, controllers, and recorders. Its rugged design, featuring a protective rubber boot and backlit display, makes it equally suitable for the laboratory bench or the harsh environment of a processing plant. With features like automatic RTD wire detection and the rapid “EZ-CHECK” switch, the CL543B significantly reduces the time required for routine maintenance and troubleshooting.

Omega CL543B Key Features & Benefits

• Universal Sensor Support: Compatible with 14 thermocouple types (including K, J, T, E, R, S, B) and a wide range of RTD curves (Pt100, Pt1000, Cu10, Ni120).

• High-Resolution Accuracy: Offers user-selectable resolution of 0.01° or 0.1°, meeting the strict accuracy requirements needed for AMS 2750 heat treating surveys.

• Intelligent Connectivity: Automatically detects 2, 3, or 4-wire RTD connections and alerts the user to open sensor wires, simplifying complex troubleshooting.

• EZ-CHECK Function: A unique slide switch allows for instant recall of three stored calibration points (0%, 50%, 100%), streamlining linearity tests.

• Multi-Mode Operation: In addition to temperature, the device can measure and source resistance (Ohms) and millivolts (mV) for testing system cards.

• Cold Junction Compensation: Features a high-precision internal thermistor for superior cold junction accuracy (±0.05°C).

• Field-Ready Design: Powered by standard AA batteries with long operational life, housed in a casing protected against accidental drops and industrial grime.

Applications of the Omega CL543B

• Process Calibration: Verifying the accuracy of temperature transmitters and panel meters in oil, gas, and chemical plants.

• Sensor Troubleshooting: Diagnosing drift or failure in installed RTD and Thermocouple sensors.

• Quality Control: Used as a portable secondary standard for validating equipment in food processing and pharmaceuticals.

• Heat Treatment: Compliance testing for furnaces and ovens requiring high-precision documentation.
