Ultra-Low Temperature Measurement Calibration

We Calibrate Ultra-Cold or Ultra-Low Temperature Devices

TesCom Calibration & Repair Services recently expanded its calibration capabilities to include specialized services for ‘ultra-cold’ wireless (and other) remote logging wireless temperature sensors including refrigerators and freezers used where CDC ‘cold chain’ temperatures are critical, for temperatures as low as -95^o C; and with calibration measurement accuracy of less than about +/-0.02^o C.

Our calibration method uses a High Accuracy Ultra-Cold Temperature Drywell, externally monitored by a High Accuracy SPRT; at customer specified temperatures, and includes optimized accuracy at customer specified critical temperatures (normally to within +/-0.5^o C).  Our calibration laboratory is ISO17025 Accredited for temperature measurements and temperature mapping protocols for devices that are used in the pharmaceutical industry, food manufacturing and even industrial applications.

Although ‘ultra-cold’ temperature measurement is not new, the Global COVID-19 Pandemic of 2020 has brought needs for this type of temperature measurement to the forefront. So for the purpose of this article, ‘ultra-cold’ refers to measurements of temperatures between -45^o and -95^o Celsius.

Producing or distributing new COVID-19 vaccines requires among other things, the need to continuously store them at proper temperatures. Depending on requirements of the specific vaccine, this may require refrigeration (from +2^o to +8^o C), frozen (from -15^o to -25^o C), or ‘ultra-cold’ storage (from -60^o to -80^o C).
