The structure of this unit series works with a ColdBrain electronic board. ColdBrain uses three microprocessors and can trace readouts with ease. This uses an on-screen message system and can store data for three months or more. The SD card can also download and transfer temperature data with ease. It works for freezers with ease and can transfer data to PCs as needed. The alarms for failures and battery issues are easy to hear. There's a backup battery in the setup too. It also has a full Ethernet link. This keeps temperatures stable and uses a low noise total. The Bioguard system can be used on RFID user cards and a chart recorder makes readouts easier to manage. This sensible design system is fully certified to work as a medical device.
