Data Logger Provides Ultra-Low Temperature Readings
This new device from Omega Engineering has a -86°C low temperature performance, which should make it a worthy candidate to consider for dry ice applications.
For reference, the BioPharma industry veteran Sensitech’s TempTale Probeless Dry Ice unit is rated at -80°C, which is quite close to the sublimation temperature of dry ice of -78.5°C.
Also worthy of mention, is another leading BioPharma temperature monitor manufacturer, the Swiss company Elpro, which has the Ti1-D Libero USB device, which is rated at -90°C.
The further the low end of the specification is, the greater the assurance against a possible low temperature related failure – a concern with battery powered devices, since battery voltages are susceptible to low temperature – thus, a critical consideration with dry ice applications.
The OM-CP-CRYO-TEMP ultra-low temperature data logger from Omega Engineering records temperatures as low as -86°C. The logger is a stand-alone device and does not require any additional probes. The enclosure is designed with a handle for easy attachment and is IP65 splash resistant. The logger uses a USB docking station to communicate with a personal computer or laptop. The OM-CP-CRYO-TEMP provides date-and-time stamped temperature readings. Using Omega’s software, the user can view the data in graphical or tabular form. High and low alarm limits and high and low warning limits can be programmed through the software. The user can set the alarm limits in the range required, and the warning limits can be set to alert the user when the temperature is nearing a high or low alarm limit, so that proper action can be taken to ensure the integrity of the goods. The logger is also equipped with three LED lights: a green LED that blinks while the recorder is logging data, a yellow LED that blinks when the temperature has breached the warning limits, and a red LED that blinks when the temperature alarm limits have been exceeded.
