WE CALIBRATE THESE HUMIDITY AND TEMPERATURE ITEMS.
Garber Metrology’s precise and reliable temperature and humidity calibration services provide high-accuracy calibration according to industry standards. We are ISO 9001 Registered by NQA and ISO/IEC 17025 and ANSI/NCSL Z540-1-1994 Accredited by ANAB.
We provide calibration services both in-house and on-site for your convenience. About 70% of our services are performed at customer facilities, while the rest are performed in our dedicated, environment-controlled laboratories. Our highly trained staff is equipped to produce precise temperature and humidity calibrations no matter where they are.
How to Calibrate Humidity
Humidity is measured with a tool called a hygrometer. It measures the percentage of water vapor in the air to determine a given space’s exact humidity. Hygrometers are calibrated by comparing the meter’s output to a known output or environment. For humidity specifically, calibration technicians must create a sealed space with a known humidity level that is stable and unchanging.
Technicians then place the hygrometer in the space and read the output. If the output of the hygrometer matches that of the known humidity, it is properly calibrated. If not, it should be adjusted to meet the known level.
How to Calibrate Temperature
Thermometers can take many forms, all of which may be tested in different ways. Generally, the best way to calibrate a thermometer is to physically heat or cool the sensors to a known temperature, then compare the output. If the thermometer does not provide the known temperature, it should be adjusted.
To properly calibrate a thermometer, the known heat source needs to be stable and uniform. It should not change over time or depend on where the thermometer’s sensors are located.
