Do you use ice and boiling water to calibrate temperature? There's a better way.
Fluke Calibration Blog
by Travis Porter

Using ice and boiling water to calibrate temperature is easy and fast. However, the water method can be inaccurate because of variations in altitude, atmospheric pressure and water purity -- and the inaccuracies are unknown. When you're calibrating you want to avoid as many unknowns and inaccuracies as possible. Using a dry-block calibrator is a far better way to calibrate temperature. A dry-block provides a better measurement because it has a known accuracy. read more ..read more

How to calibrate a thermocouple
Fluke Calibration Blog
by Steve Potter
3y ago
Thermocouples are common in industry because they are inexpensive and cover a wide temperature range. They should be tested during commissioning and again when removed from a process to verify that the tolerances were met. You’ll also want to test thermocouples at regular calibration intervals and if you suspect them of failing to meet performance specifications. read more ..read more

Are you using a deadweight tester or piston gauge? Be sure to account for gravity
Fluke Calibration Blog
by Tim Francis
3y ago
To establish pressures using a deadweight tester (DWT) or piston gauge, you need to account for the acceleration of gravity where the instrument is operated. Gravity varies around the world. With a range of approximately 0.5 %, the local gravity correction is typically the largest environmental influence acting on the deadweight tester. read more ..read more

Three excellent reasons to choose a modular pressure calibrator over a more traditional solution
Fluke Calibration Blog
by Tim Francis
3y ago
From a high level view, all pressure calibration systems perform these actions: Generate and control a pressure. Measure the pressure. Observe and record the output of the device under test (DUT). In a traditional pressure calibration system, one device performs more than one of these functions. In a modular system, each function is performed by a separate module. Why might you prefer a modular solution? read more ..read more
