UCT15: Ultra-cold temperature sensor 

for cold-chains, with resistance temperature detector (RTD) type platinum tip-sensor and accurate readings to -328°F 

This ultra-cold temperature sensor is suitable for monitoring a wider range of temperatures from -328° to 302°F (-200° to +150°C).

The ultra-cold sensor is based on a resistance temperature detector (RTD) made from platinum. As temperature changes so does the resistance of the metal. This is precisely measured to give a temperature reading.

The accuracy of the sensor is ±0.4°F (±0.2°C) and it is typically used for ultra-cold shipments such as the mRNA-based COVID-19 vaccines from Pfizer and Moderna.

UCT15 is a PT100-type* of platinum-wire temperature sensor that is based on the principle of measuring the resistance of a platinum wire. It has an accurate voltage applied to it and the platinum wire's resistance would be a known value. The ambient temperature affects the temperature of the wire and thus the resistance is measured.

This sensor is compatible with the sensorProbe+ platform only.

Custom (Longer) Lengths
Custom (longer) lengths (up to 60 feet) of this sensor are available by ordering as many extended-feet in length (listed below, up to 45 feet) to match the total cable-length that you need.

Example: If you need a 40-foot long Temperature Sensor, you should order:
1x Ultra-Cold Temperature Sensor, 15 Feet [UCT15] - This product
25x Extra 1-Foot Fixed Cable-Length for Ultra-Cold Temperature Sensor [UCTxx] - Listed below
This will get you a 40-Foot Fixed-Length Ultra-Cold Temperature Sensor.

Note: This fixed-length temperature sensor is not designed to be field-extended. Order a custom length if you need a longer cable length. AKCP does not recommend connecting the temperature sensor though patch panels, or using RJ-45 couplers to extend it.

* PT100-type means the resistance is 100 ohms at a temperature of 0 degrees C.
