A precision relative humidity and temperature probe which connects directly to the XR5 Data Logger, no external power required. Uses two XR5 input channels, one for temperature (dry bulb) and one for %RH.
| Specifications - PACE Temperature / RH Probe | |
| RH Accuracy | ±3% RH from 0 to 95% RH |
| Stability | ±1% RH typ. at 50% RH in 5 years |
| Repeatability | ±0.5% RH |
| Temperature Accuracy (using XR5 Data Logger) | ±0.15°C from 0 to 40°C (±0.27°F from 32 to 104°F) ±0.3°C from -25 to 85°C (±0.55°F from -13 to 185°F) |
| Temperature Sensor Interchangeability | ±0.1°C from 0 to 70°C |
| Physical | Rugged housing with sintered stainless steel filter. |
| Size | 0.5" dia. x 2.5" long (13mm x 64mm) |
| Operating Temperature | -40 to 85°C* (-40 to 185°F)* |
*Continuous use above 70°C (158°F) in high humidity environments (above 70%RH) is not recommended.
The Temperature / Relative Humidity Probe is available with four leads lengths as detailed below:
| Available Models | ||
| Part No. | Lead length | Price |

| TRH-160-10FT | 10ft shielded cable (3 meter) | $225. |
| TRH-160-20FT | 20ft shielded cable (6 meter) | $233. |
| TRH-160-50FT | 50ft shielded cable (15 meter) | $257. |
Comparing the TRH-160 and TRH-100 Probes:
The TRH-160 Probe has a nominal dc voltage output of.0.5 - 2v, originally designed for the 0-2.5v inputs of the older Pace XR5-8 series data loggers. The TRH-100 Probe has a nominal dc voltage output of 1.0 - 4.0v, originally designed for the Pace Pocket Logger's 0 - 5v inputs. The rest of the internal electronics, as well as the temperature and humidity sensors in both probes, are identical, as are their physical appearance and construction. Since the XR5-SE Data Logger's analog inputs can be set for 0-2.5 or 0-5v, either probe works fine with any model of the XR5-SE family, and LogXR Software supports both probes. However, Pocket Logger Software supports only the TRH-100.
