Data loggers are often used in highly regulated environments such as food and pharmaceutical production and storage where strict safety regulations apply. Regulatory agencies generally require proof of calibration.
ACR calibrations are performed using reference standards that have been calibrated and are traceable to the US National Institute of Standards & Technology (NIST). This ensures that all ACR data loggers meet, and perform to, their published specifications, allowing you to be confident that they will assist you in achieving your compliance requirements.
Calibration certificates are provided with every calibration we perform. ACR Systems is an ISO 9001:2015 registered company and calibration records are kept as part of our quality system and can be made available for customer audits.
