We are adding a new thermistor, the 109SS-L, to our product line. The 109SS is essentially the same probe as our 109-L Temperature Probe, except it has a stainless-steel housing. The stainless-steel housing allows the 109SS to be submerged or buried in harsh, corrosive, or hot environments. The 109SS measures temperature from -50° to +70°C, and is compatible with most currently-available dataloggers.
