109SS-L Stainless Steel Temperature Probe

ClimateMeteorological Station & Sensors

The 109SS is a rugged, accurate probe that measures soil or water temperature from -40° to +70°C. The 109SS consists of a thermistor encased in a sheath made from grade 316L stainless steel. The rugged stainless-steel sheath protects the thermistor, allowing you to bury or submerge the 109SS in harsh, corrosive environments. This probe also has a fast time response, and it can be easily interfaced with our data loggers.

Specification

Output	Analog
Operating Temperature Range	-40° to +70°C
Accuracy	Note: Overall probe accuracy is a combination of thermistor interchangeability, bridge-resistor accuracy, and error of the Steinhart-Hart equation. Interchangeability is the principle component error. If needed, an estimate of the interchangeability error for 0 to 50°C, that can be used as the *Offset* parameter of the Therm109() instruction, can be determined with a 1-point or 2-point calibration. ±0.60°C (-40 to +70°C) ±0.49°C (-20 to +70°C)
Maximum Submergence	45.7 m (150 ft) or 434 kPa (63 psi)
Temperature Measurement Range	-40° to +70°C
