When precise temperature measurements are required, WPI can provide you with a very accurate monitor and thermocouple microprobes. WPI monitors have both resolution and accuracy of 0.1 °C in the 0 to 50 °C range and are traceable to NIST standards, whereas other competitive electronic thermometers have an accuracy that is usually to 0.5 °C or worse. Furthermore, all our type T clinical probes are guaranteed accurate to 0.1 °C, due to our stringent wire standards. These are five times more accurate than competitive probes made with regular 'Special Limits' wire.
