Testo Robust Humidity Probe
Testo Robust Humidity Probe
The Testo Robust Humidity Probe is a high-durability sensor module engineered for precise air temperature and relative humidity diagnostics within harsh industrial environments and commercial HVAC networks. Capable of operating in ambient temperatures reaching up to 125 degrees Celsius, this instrument is perfectly suited for air exhaust ducts and high-heat processing zones. When paired with compatible base units, it also calculates material equilibrium moisture content for bulk goods and structural building diagnostics. It features a long-term stable capacitive sensing core that maintains a drift rate of only 1% RH per year, ensuring consistent, reliable data accuracy during extended field deployments.

KEY FEATURES
- Measures relative humidity and air temperature precisely
- Material equilibrium moisture measurement capability (with Testo 635)
- Wide temperature range: -20 to +125 °C (briefly up to +140 °C)
- Durable design for long-term industrial use
- Long-term stable humidity sensor (±1 %RH per year)
- Suitable for air ducts, storage, and building materials
- Compatible with Testo 635, 435-2, and 435-4 instruments
The Testo 0636 2161 Robust Humidity Probe delivers a premier technical solution for executing environmental diagnostics inside demanding high-temperature loops. Standard environmental sensors are frequently constrained by thermal ceilings that prevent them from entering active exhaust lines or industrial drying chambers; by engineering a probe assembly that withstands continuous temperatures up to +125 °C and intermittent spikes up to +140 °C, this tool bridges the gap between standard HVAC monitoring and heavy-duty industrial process control. Whether checking ambient climate variables or evaluating the internal equilibrium moisture of stacked bulk materials, the probe utilizes a high-precision NTC thermistor and capacitive grid to return stable, drift-free psychrometric data.
ADDITIONAL FEATURES
- Extended thermal threshold accommodates brief peak exposures up to +140 °C without structural damage
- Substantial 300 mm shaft length allows for deep, stable insertion profiles within large-scale ventilation ductwork
- Dual-purpose functionality switches between climate monitoring and material moisture analysis depending on the host device
- Minimal annual sensor drift of ±1 %RH preserves calibration integrity throughout multi-year operational life cycles
- Rugged 12 mm diameter stainless steel shaft resists mechanical wear in fast-moving air streams
APPLICATIONS
- Perfectly optimized for high-temperature humidity tracking, industrial exhaust duct auditing, bulk material moisture testing, and structural building diagnostics across commercial and manufacturing environments.
