The FlashLink Certified Vaccine Data Logger with Glycol Bottle is designed for monitoring temperature conditions inside storage units where vaccines and other temperature sensitive pharmaceuticals are kept. This reusable logger features a large, easy-to-read LCD and an external probe sealed in a 5mL glycol bottle. The glycol prevents false alarms by buffering the probe against sudden and expected temperature fluctuations during normal use, such as frequent door openings and cycling of the refrigerator or freezer. The glycol also emulates temperature changes experienced by most common fluids in storage, to give more accurate readings. The logger attaches to the outside of the storage door, while the sensor bottle is placed inside, allowing users to read current and minimum/maximum temperatures without opening the unit. A red LED alarm and low battery indicator are also visible on the display. This logger is prequalified by the World Health Organization (WHO) as an E006 Temperature Monitoring Device, under their Performance Quality Safety code PQS E006/026, and is compatible with FDA, CDC and WHO guidelines. Model 20938 includes a 2 year ISO 17025 calibration certificate.
