Temperature Instrument Calibration

Accurate Temperature Reference Standards Calibration for the Life Sciences

Pharmaceutical, medical device and biotechnology companies depend on the accuracy of their equipment, which is why they depend on Alcami to confirm that accuracy. With our industry-leading and SI traceable temperature calibration services, you can count on us to make sure your temperature standards, thermometers and sensors are precise.

Temperature calibration is a critical process in any GLP lab and GMP manufacturing environment. When your thermometry standards are correctly calibrated, you don’t have to worry about the integrity of your production chain. Accurate temperature reference standards ensure product safety and efficacy, in addition to assuring that operations are profitable.

Maximum Accuracy and Minimal Measurement Uncertainty in Primary Standards Calibration

When you choose Alcami for your primary standards calibration, you get Alcami’s commitment to quality and excellence. We provide maximum accuracy and minimal measurement uncertainty for primary standards and laboratory instruments. Our expert team performs reference thermometry calibrations in our 10,000-ft2 environmentally controlled calibration lab, one of the few labs in the country that meet the rigorous qualifications for  accreditation to ISO 17025:2017 through ANAB.

The lab is environmentally controlled, maintained at 21.5°C (±0.5 °C) and 40% RH (±5%) to ensure accurate and repeatable results in temperature calibration, featuring the highest-quality thermometer calibration standards and state-of-the-art calibration technology. Your temperature equipment will achieve maximum accuracy with our primary standards calibrations to SPRTs and NIST certified fixed-point cells.

We offer SI traceable thermometry calibration from -196°C through 1200°C as well as ANAB accredited set point calibration in the -189°C to 660°C range.

Consistently Accurate Results

When you enhance the quality, accuracy and regulatory compliance of your thermometry instruments, you improve the integrity of your end products. Alcami reduces the threat of even the smallest inaccuracies, so you can have confidence in your thermometry devices. We work with you to find the solution that fits your needs, whether that’s calibrating a single device or a large inventory of thermometry instruments.

Monitoring lab conditions throughout your calibration cycle is critical to accurate results. Alcami monitors our lab conditions 24/7 and halts calibrations if conditions stray from your environmental specifications. We record the environmental conditions on each calibration certificate to build greater confidence in our calibration services.

We are proud to be Accredited to ISO/IEC 17025:2017 through ANAB, and all primary reference standards are traceable to recognized International Standards, allowing us to provide optimal measurement accuracy. Many of Alcami's primary reference standards are sent directly to NIST for calibration and direct traceability.
