● Advantages of Field Calibration

Greater speed: You can often save time by choosing field tuning services over lab tuning services. Since the technician comes to your facility, you don’t have to take the time to pack up the equipment and ship it to a lab. While lab calibration can also be fast, mobile calibration often has the edge in speed because there’s no shipping involved in the process. Since field services can be quicker, you can reduce downtime and get back to work faster.

Easier total loop calibration: When you want to calibrate an entire measurement loop, field calibration is usually the better choice. It allows a company to adjust their entire system without having to uninstall all of it and send it out to a lab, which can take a great deal of time and lower productivity.

Improved transparency: Some companies want to review the calibration process from the beginning to the end. Since technicians work at their clients’ facilities, on-site calibration is a perfect fit for companies that want an entirely transparent process.

Reduced costs: When you ship your equipment to a lab, you usually have to factor in handling and shipping costs. Field calibration removes these costs by sending the technician directly to you, saving you money as a result.

● When to Use Field Calibration

If your equipment doesn’t need particular environments that your facility can’t offer and you want to avoid uninstalling your equipment for total loop calibration, requesting field calibration can be a great choice. For those who want a more convenient, quick process and total transparency, field calibration is often a good fit.

● Metrology performance for high-accuracy measurements

Unlike traditional dry-wells, Field Metrology Wells maximize speed and portability without compromising the six key metrology performance criteria laid out by the EA: accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, loading, and hysteresis. All criteria are important in ensuring accurate measurements in all calibration applications. Field Metrology Well displays are calibrated with high quality traceable and accredited PRTs. Each device (process and non-process versions) comes with an IEC-17025 NVLAP-accredited calibration certificate, which is backed by a robust uncertainty analysis that considers temperature gradients, loading effects, and hysteresis.

● Automation and documentation make each unit a turnkey solution

So you now have a precision calibration instrument that has field-ready characteristics, accredited metrology performance, built-in two-channel thermometry, and automation— what else could you ask for? How about all this and a turnkey solution that will automate and document the results?

The process versions of Field Metrology Wells have onboard non-volatile memory for documentation of up to 20 tests. Each test can be given a unique alphanumeric ID and will record block temperature, reference temperature, UUT values, error, date, and time.

● Operation is as easy as 1-2-3

You’ll find Field Metrology Wells intuitive and easy to use. Each unit is equipped with a large, easy-to-read LCD display, function keys, and menu navigation buttons. Its “SET PT.” button makes it straightforward and simple to set the block temperature. Each product has a stability indicator that visually and audibly tells you the Field Metrology Wells is stable to the selectable criteria. Each unit offers preprogrammed calibration routines stored in memory for easy recall, and all inputs are easily accessible via the front panel of the instrument. Never buy a temperature calibration tool from a company that only dabbles in metrology (or doesn’t even know the word).

Metrology Wells from Dearto are designed and manufactured by the same people who equip the calibration laboratories of the world’s leading temperature scientists. These are the people around the world who decide what a Kelvin is! We know a thing or two more about temperature calibration than the vast majority of the world’s dry-well suppliers. Yes, they can connect a piece of metal to a heater and a control sensor. But we invite you to compare all our specs against the few that they publish. (And by the way, we meet our specs!).

● Small dry wells for big field applications

Field Metrology Wells are packed with functionality and are remarkably easy to use. They are lightweight, small, and quick to reach temperature set points, yet they are stable, uniform, and accurate. These industrial temperature loop calibrators are perfect for performing transmitter loop calibrations, comparison calibrations, or simple checks of thermocouple sensors. With the “process” option, there is no need to carry additional tools into the field.
