Tip #7
Boost calibrator accuracy with a platinum resistance thermometer (PRT)

The convenience of a handheld dry-well is very appealing but sometimes you need a little more accuracy. A great way to improve the accuracy of any dry-well is to use a platinum resistance temperature standard for your known temperature instead of the calibrator display. The best dry-block calibrators can directly read PRT standards to improve their display accuracy. A good example is the Field Metrology Well process version.

Tip #8
Use a dry-well or Metrology Well to eliminate messy fluids

One great thing about dry-wells is they are dry. That means you don’t have to deal with a lot of messy fluids. This can be very helpful if cleanliness is one of your chief requirements. Of course there are ways to keep bath fluids from becoming a mess, but why bother if you don’t have to? Fluke 9170 Series Metrology Wells are so accurate they can be used as an alternative to a calibration bath in many applications. We use Metrology Wells in our lab for certain calibrations, and you can do that too or take them onsite.

Tip #9
Calibrate more workload with a calibration bath

The great thing about a calibration bath is that the working area can be large enough to calibrate several probes at a time (our laboratory usually calibrates 10 at a time), and the probes can have a range of shapes and sizes. So if your customers or coworkers may bring you anything under the sun to calibrate then you definitely want a calibration bath. But, what if you still need to calibrate all of those different kinds of probes onsite? Use a Micro-Bath. They are easily carried in one hand, but still have many calibration bath advantages.

Tip #10
Conveniently check devices onsite with a handheld dry-well

If you’re just getting started with temperature calibration you probably want to look at the 611A dry-wells. Anyone can learn to use one in less than 15 minutes, they are inexpensive, and they literally fit in the palm of your hand. You can use them to easily check RTDs, thermocouples and small dial thermometers because the display accuracy is ±0.25 °C.
