Relative Humidity

Calibrating Critical Relative Humidity Standards and Sensors

Accurate humidity measurement is critical because it supports the stability, controllability, and repeatability of your moisture-sensitive production processes. When these measurements are off, the entire production line of pharmaceutical, medical device, and biotechnology products may be compromised. Correct humidity standards and sensors are significant in biopharma applications such as incubators, stability chambers, and drying rooms.

Relative Humidity Calibration Capabilities

Alcami’s relative humidity calibration capabilities include 10–95% RH at 0 °C–70 °C, all ANAB accredited. For exceptional accuracy we perform all calibrations with the two-pressure Thunder Scientific 2500 humidity chamber.

The Thunder Scientific humidity chamber is Alcami’s most trusted primary standard for calibration projects. We provide you with calibrations that will improve your moisture-sensitive environments and products.

Consistently Accurate Results

Alcami is your trusted choice for humidity sensors and instrument calibration. Our expert team is proud to provide the highest precision and the lowest possible error rate. We understand how critical the correct relative humidity level is to a lab or production environment, and we calibrate it right the first time, every time.

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.
