Monitor fluid temperature with AVTECH's Digital Fluid Temperature Sensor. Each AVTECH Digital Fluid Temperature Sensor provides real-time temperature values from -67 to 257 degrees Fahrenheit and/or -55 to 125 degrees Celsius. Accuracy is within + / - 2 C degrees. Each temperature probe is encased in a sealed tube containing Propylene Glycol. Propylene Glycol is a colorless liquid with extremely low freezing and high boiling points. Its non-conductive nature makes it a perfect sensor for monitoring fluid temperature in extreme environments such as labs that monitor vaccines, plasma, IV bags and/or other specimens, aquariums, refrigeration devices or other locations where fluid temperature must be monitored and/or regulated. This is a dynamic sensor that provides temperature values every two seconds and feeds temperature data back to the Room Alert ID box for data logging, alerting and automatic corrective action. This is an instant 'Plug & Play' sensor via one of the standard RJ-11 jacks on any compatible Room Alert monitor. AVTECH offers this sensor with cable lengths of 25', 50' and 100'.
