ACR A2LA Accredited Temperature & Relative Humidity Calibration 

ACR Technical Services, Inc. provides the best in temperature and relative humidity metrology and calibration services.

ACR has the capabilities for performing temperature calibrations on almost any type of temperature measurement or control instrument. Keeping your instruments in good working order as part of the many calibration services we provide. By utilizing ACR‘s temperature calibration services, you can establish a yearly schedule to meet the standards your needs.

Our facility is ISO/IEC 17025 compliant and accredited by NIST/NVLAP for comparison temperature calibrations. Each instrument is calibrated in our world class metrology laboratory utilizing the latest equipment and training from ASL/Isotech providing the lowest uncertainties available in the market place. ACR performs calibrations with primary standards directly traceable to the National Institute of Standards and Technology (NIST).

Primary, fixed-point temperature calibrations yield the highest accuracies suitable for calibrating in-house temperature standards and high precision devices. Secondary comparison temperature calibrations are suitable for less accurate temperature measuring devices.

At ACR we also have the expertise and capability of calibrating all types and sizes of humidity instrumentation. Our chambers can control and measure humidity, pressure and temperature simultaneously. ACR maintains a comprehensive humidity calibration laboratory with direct traceability to the national humidity standards of the National Institute for Standards and Technology (NIST). All of our calibration systems have this traceability.
