Practical information for Vu+’s plug-in Temperature sensor
The sensor has a particularly low thermal inertia. The thermistor is housed at the end of the
stainless steel tube, so it is the tip of the sensor that is most sensitive to temperature.
Lay the sensor on its side, not its end, when measuring a surface temperature.
Do NOT put any part of the sensor in a direct flame or on a hot plate.
Temperatures higher than 150ºC will damage the sensor.
The PVC insulation on the connecting cable has a working range of -10 to 85ºC, so keep this
cable away from the source of heat.
Avoid submerging the sensor beyond the stainless steel portion.
Wash the sensor thoroughly after use.
The boiling point of water will vary with changes in air pressure. At one atmosphere of pressure
(101.3 kPa, 1013 mBar) pure water boils at 100ºC. Water boils when the vapour pressure of
water equals the pressure of the gases above water, so if the pressure changes, then the
temperature that the water boils at will also change.
