Process Calibrators

The most sophisticated industrial equipment will not be useful unless it is calibrated. A Process calibrator is used to adjust an instrument accuracy, often with a specific application. GAOTek Process Calibrators can help you in calibrating instruments and is also used during troubleshooting. It can perform various tasks so quickly and so well, that it’s the only process calibrator you need to carry. It can calibrate temperature, pressure, voltage, resistance and frequency. Through calibration, one can ensure that any equipment performs as expected that it can be relied on to deliver predictable, accurate results that meet quality standards. GAOTek Process Calibrators come with an USB interface which makes it easier to transfer the results to a PC which otherwise would have taken a long time to transcribe them.


The Process Calibrators are often associated with a certification process, where a certificate of calibration assures an end user with the product’s conformance with specifications set by the International Organization for Standardization. ISO 9001 standards set worldwide specifications for business sectors.

GAOTek’s Process Calibrators follow the HART (Highway Addressable Remote Transducer) 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 Calibrators supports popular instrumentation management software. It can work with popular programs from Honeywell, Meridium, Emerson, Cornerstone, Yokogawa, Prime Technologies, Intergraph, and others. It allows you to create procedures, instructions, and action lists to deliver fast, easy documentation.

It’s a hand-held device. It can easily fit into a tool-bag and to use in tight places. Calibrators offer one- or two-year calibration cycles and three-year warranty. It runs on an entire shift on a rechargeable Li-ion battery pack.

The display screen is bright and allows you to read the readings in any kind of light. Backlight has three settings. 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, or simultaneous Measure/Source, enable technicians to troubleshoot, calibrate, or maintain instrumentation with just one tool. Integrated HART communication capability lets you program and control HART instrumentation.

It has a multi-lingual instruction display in English, French, German, Spanish, and Italian. The Auto-Step allows technicians to set the calibrator for a delayed start and a specific sequence of steps, so it can run when it’s unattended. Custom units allow readings to be scaled and displayed in any user-defined units. Switch calibration procedures perform fast, automated calibration of one- and two-point switches for voltage, current, temperature, and pressure.


Finding the right tools for the specific challenges you face every day is important, so we provide you here “at-a-glance” guide to the wide range of multifunction, mA loop, pressure, and temperature calibrators that we carry. For example, working in a process environment such as pharmaceutical, refining or other industrial area can be challenging. Working in any area always demands accurate tools that one can count on. GAOTek provides a solution to this with a wide range of Process Calibrators.

GAOTek offers a broad range of field and bench calibrators to source, simulate, and measure pressure, temperature, and electrical signals to help you verify and adjust your test equipment or almost any process instrument.

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

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

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. Temperature calibration is used in a device which measures temperature-from sensors to transmitters and displays.

Temperature calibration refers to the calibration of any device used in a system that measures temperature—from sensors to transmitters to displays. 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.
