Digital Pocket Psychrometer
The DTH35 is a compact HVAC/R diagnostic instrument for fast air temperature, relative humidity, wet bulb, dew point and enthalpy readings on site.
Technical snapshot
Key DTH35 measurement specs.
A compact view of the main ranges used for everyday HVAC/R diagnostics.Airside diagnostics
Measure humidity fast and calculate the values HVAC/R techs use every day.
The DTH35 Digital Psychrometer gives technicians a quick way to check air temperature and relative humidity, then calculate wet bulb temperature, dew point and enthalpy for more complete airside diagnostics.
- Compact digital psychrometer for HVAC/R diagnostic work.
- Measures air temperature and relative humidity.
- Calculates wet bulb temperature, dew point and enthalpy.
- Temperature range from -20°C to 50°C.
- Relative humidity range from 0.1% to 99.9% RH.
- Slim probe design for ducts, vents, grilles and return air openings.
What it measures
Use the DTH35 when you need quick, repeatable comfort and moisture readings without a bulky meter setup. It measures air temperature and relative humidity directly, then calculates the key psychrometric values used for HVAC/R airside checks.
- Direct readings: air temperature and relative humidity.
- Calculated values: wet bulb, dew point and enthalpy.
- Ideal for comfort checks, airside diagnostics and quick moisture assessment.
Service applications
Built for commissioning, maintenance and troubleshooting.
A pocket psychrometer is useful anywhere airflow conditions need to be checked quickly. The DTH35 helps technicians assess cooling performance, ventilation conditions and moisture levels during day-to-day HVAC/R work.
Use it for
Fast comfort and airside checks on site.
Use the DTH35 when you need a quick snapshot of the air conditions around a duct, vent, grille or return air opening. It gives the direct readings and calculated values needed to support everyday HVAC/R diagnosis.
- Commissioning checks when verifying system setup and airside performance.
- Routine maintenance checks for comfort conditions, humidity and moisture levels.
- Troubleshooting support for cooling performance, ventilation issues and humidity complaints.
Slim probe design
Easy to use in ducts, vents and return air openings.
The slim probe makes it easier to position the sensor where the airside reading is needed, while the compact body keeps the tool easy to carry in a service bag.
Calculated psychrometric values
Get more than temperature and RH.
By calculating wet bulb, dew point and enthalpy, the DTH35 helps technicians make better sense of moisture, comfort and cooling-performance readings during HVAC/R service work.
