E.g. Boiling Point of Water vs. Pressure
AISI 316 stainless steel has a high resistance to corrosion from a wide variety of weak acid and
alkali. 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 Sulfuric acid (H
2
SO
4
).
The maximum recommended times for exposure are:
To set the range
The Smart Wireless Temperature sensor has 2 ranges, Centigrade and Fahrenheit. The sensors are
supplied calibrated, with Centigrade as the default range.
To alter the range in the EasySense2 software:
