Our LogTag VAC-UTRED30-KIT-1 is a complete solution for monitoring vaccines stored in both refrigerators and freezers. The large easy to read display is designed to show ‘at a glance' if temperature excursions have occurred during the current day and up to the previous 29 days. Alarms are customizable during configuration, which is handled by the powerful, easy to use, free LogTag Analyzer software. The logger can be AC powered using the included AC adaptor and USB cable as well as by 2 AAA batteries. The logger also features a backup coin cell battery. At the heart of the kit is the LogTag UTRED30-16 logger which has inputs for two external probes allowing you to monitor both a fridge and freezer with a single device. The additional probes can be purchased separately or can be purchased as a kit with the VAC-UTRED30-KIT-2. Additionally, the logger is compatible with the LogTag CP100 Smart Probes which allow you to swap out pre-calibrated probes without having to ship the logger back for re-calibration. We offer Smart Probe kits in both single probe, VAC-UTRED30-CP100-KIT, and dual probe, VAC-UTRED30-CP100-KIT-2 versions. The kit includes everything you need to meet state health departments and the CDC for safe vaccine monitoring and storage. It includes the logger, sensor probe with glycol buffer bottles, calibration certificate, and mounting accessories.
