Digital Pocket Psychrometer

The UEI DTH35 Digital Psychrometer is a compact HVAC/R diagnostic instrument designed for fast, accurate airside measurements. It gives technicians clear readings for air temperature and relative humidity, while also calculating key HVAC values including wet bulb temperature, dew point and enthalpy.

With a temperature range of -20°C to 50°C and relative humidity measurement from 0.1% to 99.9%, the DTH35 is a versatile tool for day-to-day system checks, commissioning, maintenance and troubleshooting. Its slim probe design makes it easy to use in ducts, vents, grilles and return air openings, helping technicians quickly assess airflow conditions and overall system performance.

Ideal for air conditioning, refrigeration and ventilation work, the DTH35 helps support accurate diagnostics when checking comfort conditions, moisture levels, cooling performance and airside calculations.
