The FlashLink Wireless Dry-Ice [-80°C] Sensor with External Thermistor Probe is designed and tested to measure cryogenic temperatures down to -80°C or -112°F. Composed of a highly accurate temperature thermistor and a robust 418MHz radio transmitter, this sensor is especially well suited for remote monitoring and reporting of temperatures of cryogenically stored materials, such as body organs and epoxy sheets, in the range of -80°C to -10°C (-112°F to 14°F).  The sensor comes with a 1.2m (4ft) teflon coated extension cable which is connected to the thermistor.  The playing card deck-sized transmitter is made from durable, impact-resistant ABS plastics and is N.I.S.T. traceable, FCC Part 15-compliant and with CE Mark for the European market.

Installing the sensor is as easy as placing it anywhere up to 600 feet away from the nearest repeater, and pressing the "ON" button.  A FlashLink Wireless Repeater (model 20121) should be placed between the sensor and the 900MHz Receiver to enable communication between the sensor and the receiver. Potentially an unlimited number of repeaters can be placed throughout the facility, giving unlimited scalability.  Up to 100 of  -80°C Sensors with External Thermistor Probe (or mixture of the four types of sensors: models 20124, 20126, 20129 and 20151) can be monitored by one computer server or multiple computer servers.  Receivers can be set up inside the facility to monitor hundreds of sensors.

Reasons for using the FlashLink Wireless System:
  • There are many locations to be monitored
  • These locations usually contain environmentally sensitive and expensive materials
  • HACCP, QA or regulatory guidelines require a system to monitor environmental conditions
  • Track and log all data collected by the system
  • Real-time over-the-phone alarm feature
  • Let the sensors and software do all the monitoring work
  • FDA 21 CFR Part 11 Compliant Server Software
