Temperature & Process Calibrators

The most sophisticated industrial equipment will not be useful unless it is calibrated. GAOTek Process Calibrators are used to adjust instruments’ accuracy, and they are the only process calibrator you will ever need to carry. They can measure temperature, pressure, voltage, resistance and frequency, and can be used during troubleshooting. Through calibration, you can ensure that any equipment performs as expected and that it can be relied on to deliver predictable and accurate results that meet quality standards. GAOTek Process Calibrators come with a USB interface which makes it easier to transfer the results to other devices which otherwise would have taken a long time to transcribe them. Our Process Calibrators are for sale to the United States, Canada and globally.


Process Calibrators are usually associated with a certification process, where a certificate of calibration assures users with the product’s conformance with specifications set by the International Organization for Standardization (ISO). ISO 9001 standards define worldwide specifications for business sectors.

GAOTek Process Calibrators have a built-in OL sign indicator, auto range and data hold functions. They follow the Highway Addressable Remote Transducer (HART) protocol, HART is an industry standard developed to define the communications protocol between intelligent field devices and a control system. HART is the most widely used digital communication protocol in the process industry.


GAOTek Process Calibrators support popular instrumentation management software. They can work with popular programs from Honeywell, Meridium, Emerson, Cornerstone, Yokogawa, Prime Technologies, Intergraph, and so on. They allow you to create procedures, instructions, and action lists to deliver fast, easy documentation.

GAOTek Process Calibrators are handheld devices. They can easily fit into a tool-bag and use in tight places. The Process Calibrators offer one or two-year calibration cycles and three-year warranty. They run on an entire shift on a rechargeable Li-ion battery pack.

The display screen is bright and allows you to read in any kind of light. There are three settings for backlight. Soft keys provide one-touch access to enhanced functions such as task lists, automated procedures, scaling, min/max, stepping and ramping, and review memory. Three operating modes Measure, Source, and simultaneous Measure/Source, allow people to calibrate, troubleshoot, and maintain instrumentation. Integrated HART communication capability lets you program and control HART instrumentation.

They have a multi-lingual instruction display in English, French, German, Spanish, and Italian. Custom units allow readings to be scaled and displayed in any units you want. With the Auto-Step function, the Process Calibrators let people to set the calibrator for a specific sequence of steps and a delayed start, so they can run when they are unattended. Switch calibration procedures perform fast, automated calibration of one and two-point switches for temperature, voltage, pressure, and current.


Working in any field always requires precise tools that one can count on; GAOTek provides solutions to this with a wide range of Process Calibrators. Choosing the right tool for your problems is very important, so GAOTek provides you a guide to the wide range of multifunction, temperature, mA loop, and pressure calibrators.

GAOTek offers a large collection of field and bench calibrators to simulate, source, and measure temperature, voltage, frequency, and electrical signals to help you verify and adjust almost any equipment.

Loop calibrators are essential tools for working with 4-20 mA current loops. GAOTek Loop Calibrators provide mA sourcing, measurement and simulation; readouts in both mA and % of span, 24 V loop supply, simple operation and accuracy you can count on.

The pressure, level and flow instrumentation is found almost in every process plant, so GAOTek provides a large collection of field and bench calibration tools to help you reliably and quickly calibrate your pressure and gas flow instrumentation. The periodic calibration of these instruments is very important to keep the plants operating safely and efficiently.

GAOTek provides many solutions to ensure process temperature accuracy of the system’s electronic temperature signals, and the very temperature sensors that initiate those signals. Temperature calibration is used in a device which measures temperature-from sensors to displays and transmitters.

GAOTek offers bench and field solutions to ensure process temperature accuracy of not only the system’s electronic temperature signals, but also the very temperature sensors that initiate those signals.
