Product Description

The UTREL30 low temperature vaccine data logger is a -90°C storage monitoring solution with a detailed LCD display, delivering current and historical temperature information locally via its interface and buttons.

Users can access a 30 day LCD summary of all of their data, making it quick and easy to certify safe temperature thresholds within vaccine packages. Choose to configure this ultra-low temperature data logger with a profile, where you can set recording intervals and alarm thresholds. This allows you to dictate how frequently a temperature reading is recorded, but also stay alert of any temperature thresholds so action can be taken immediately. Temperatures exceeding acceptable limits trigger both a flashing light and audible warning.

Use this vaccine data logger to periodically download temperature data via USB for audit and analysis.

Requires ST10 probe to record temperature and a WB02 bracket if the UTREL30 is being mounted on a wall or appliance.
