The thermistor sensor is at the tip of the stainless steel tube. The thermal transfer to the tube, and then to the thermistor, could make surface temperature measurement less accurate. If you need to measure the surface temperature, place the tube along the surface; probing with the tip will not allow enough heat to transfer.


Temperatures higher than 150̊0̊C (3020̊F) will damage the sensor.


Do not put any part of the sensor into a direct flame or onto a hot plate.


The electronics in the Smart Wireless module of the sensor have a working range of 0 to 400̊C, so cannot be subjected to the same extremes of temperature as the stainless steel portion. Position the sensor so that this part of the sensor is kept away from the source of heat. Take steps to protect against excessive steam.


The Smart Wireless module is not waterproof; it has an operating range of 0 to 95% RH (non-condensing). Do not place the sensor in an environment in which high humidity levels are possible,as this may result in damage or malfunction.


Do not submerge the sensor beyond the stainless steel portion.


The metal tube section can be washed after use. Clean the Smart Wireless module using a damp cloth; do not immerse in water or detergent. If the sensor has been left in the cold, let it warm to near room temperature before waking it from sleep


AISI 316 stainless steel has a high resistance to corrosion from a wide variety of weak acid and alkalis.Some environments e.g. saltwater, may cause some discolouration to the stainless steel tube but this will have no effect on the sensor’s performance.


The sensor can be left in an alkaline solution such as sodium hydroxide (NaOH) for up to 48 hours, with only minor discolouration. We do not recommend use in a solution whose concentration is greater than 3 mol dm-3. 


The maximum length of time recommended for exposure to an acid is dependent on the acid’s concentration. In general, we do not recommend that Temperature sensors be left to soak in acids of between 1 to 3 mol dm-3 concentrations for longer than 48 hours.


The exceptions to this rule are hydrochloric acid (HCl), and sulphuric acid (H2SO4).


The maximum recommended times for exposure are:  of

2 mol dm-3       10 Minutes 

3 mol dm-3         3 Minutes
