Environmental Calibration Services

Environmental calibration services help to ensure that precision measurement devices used to measure environmental conditions provide accurate results. These devices might be used to measure velocity, humidity, temperature and other environmental factors.

Michelli Weighing & Measurement offers both standard calibration and ISO 17025 calibration on a wide range of environmental measurement devices. From anemometer calibration to temperature measurement device calibration, our technicians can help. Don’t risk the quality of your readings, let the experts at Michelli Weighing & Measurement ensure the accuracy of your precision measurement devices.

Meteorological station measuring temperature and wind speed

What is environmental measurement?

Environmental measurement refers to the practice of measuring environmental factors. For example, there are times when we need to measure wind speed, pressure, temperature, or humidity. In each of these situations, a different type of precision measurement device must be used to produce accurate readings. Some of these devices include vane anemometers, thermometers, and pressure meters. Occasional calibration is required in order to ensure that these devices produce accurate measurements.

This type of measurement is used in every day life. Driving across a bridge may not be safe if the wind speed is too great. In order to determine when to close the bridge, the officials overseeing safety of the bridge might use an anemometer to gauge wind speed.

Another way environmental measurement is used daily is in food manufacturing applications. If a food storage area is too humid, the food may mold, risking the health of anyone who consumes it. Food manufacturers might use a humidity meter to ensure optimal conditions within the storage area as a quality assurance measure.

What does environmental calibration entail?

During environmental calibration, the measurement device being tested is compared to a naturally occurring physical constant, (e.g. Triple Point of Water) or a standard that produces a known value. The test device is then calibrated, or adjusted accordingly, to the standard, so that the measurement it produces matches the known value of the constant or standard. Our standards are certified traceable to the SI Units through a National Metrological Institute such as NIST, meaning that the values produced by the standard are within the stated tolerance of accuracy.

For example, let’s imagine that a vane anemometer is placed inside of a certified wind tunnel calibration unit. If the wind tunnel is set to produce wind speeds of 150 mph, a properly calibrated anemometer should produce readings of 150 mph. If the anemometer does not read 150 mph when it is tested, it will be adjusted until it does. The anemometer would be tested at multiple speeds to ensure its accuracy, as outlined in its associated calibration procedure.
