Overview
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.
Key Advantages
Can be used in a variety of applications
Technical Description
The 109SS thermistor can survive temperatures up to 100°C, but the overmolded joint and cable should not be exposed to temperatures hotter than +70°C.
Water Temperature
The sensor can be submerged to 46 m (150 ft) or 63 psi. Please note that the 109SS is not weighted. Therefore, the installer should either add a weighting system or secure the sensor to a fixed, submerged object, such as a piling.
Soil Temperature
The 109SS is suitable for shallow burial only. Placement of the sensor’s cable inside a rugged conduit may be advisable for long cable runs—especially in locations subject to digging, mowing, traffic, use of power tools, or lightning strikes.
Benefits
- Designed for harsh, corrosive environments
- Fast response time
- Wide temperature measurement range
- Easy to install or remove
- Compatible with most of our current and retired data loggers

- 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

(3)TS100SS
Aspirated Radiation Shield
The TS100SS is a fan-aspirated radiation shield that minimizes temperature-measurement errors caused by incident solar radiation. The unique aerodynamic shape and rugged, low-power fan make it the first research-grade fan-aspirated shield that is practical for use on battery- or solar-powered stations. The shield provides excellent sensor protection and accommodates various combinations of thermistors, PRTs, and humidity sensors using one of the sensor port adapter plugs.

(2)SPTEMPCAL
Single-Point Calibration of Temperature Sensor at 25°C
A single-point calibration, SPTEMPCAL, is available when a thermistor has been purchased to determine offset at 25°C. (Calibration can be made at a different value if requested by purchaser.) Calibration uncertainty is ±0.05°C. Calibration after purchase requires an RMA (Return Material Authorization).
OrderableSPTEMPCAL2
Two-Point Calibration of Temperature Sensor at 0°C and Room Temperature
A two-point calibration, SPTEMPCAL2, is available when a thermistor has been purchased. The standard two-point calibration determines offsets at 0°C and 20 to 25°C (room temperature) with an uncertainty of ±0.05°C. If a sensor uses a different temperature range or an application requires the calibration to be made at different temperature values, different temperature points can be specified when the service is requested. Calibration after purchase requires an RMA (Return Material Authorization).

Data Logger Considerations
Programming
The instruction set for our CR200(X)-series, CR800-series, CR1000, and CR3000 dataloggers contains the Therm109 instruction for measuring the 109SS probe. Programming is more complicated for other data loggers because they must use generic measurement instructions.
Installation Considerations
Soil Temperature
The 109SS is suitable for shallow burial only. Placement of the sensor’s cable inside a rugged conduit may be advisable for long cable runs—especially in locations subject to digging, mowing, traffic, use of power tools, or lightning strikes.
Water Temperature
The sensor can be submerged to 46 m (150 ft) or 63 psi. Please note that the 109SS is not weighted. Therefore, the installer should either add a weighting system or secure the sensor to a fixed, submerged object, such as a piling.
