The OM-EL-21CFR-Series loggers are ideal for applications that require secure storage of data for critical applications such as vaccine monitoring, food and beverage, and cold chain monitoring. These standalone dataloggers are capable of storing between 16,000 to 32,000 temperature or humidity readings depending on the models outlined below.

The OM-EL-21CFR-Series offers models with internal temperature sensors as well as external probe attachments which allow for a wider temperature sensing range.

The OM-EL-21CFR-VAC is specifically designed for vaccine monitoring as it is included with a glycol buffer solution and termistor probe calibrated at 2°C and 8°C which are typical storage requirements for many vaccines.

The user can easily set up the logger and view downloaded data by plugging the data logger into a PC’s USB port and using the free Omega 21CFR software. Data can then be graphed, printed and exported to other applications for detailed analysis. The encrypted data has full audit tracking to comply with the requirements of 21CFR Part 11.

The high contrast LCD can show a variety of temperature information. At the touch of a button, the user can cycle between the current, maximum and minimum stored values for temperature.

The data logger is supplied with a lithium metal battery which typically gives 2 years’ logging life.

Omega offers models that are pre-calibrated (-NIST) with calibration points outlined below. If you require custom calibration points, please give us a call and we can help you with a custom calibration solution.
