UNI-T UT333S Split-Type Digital Temperature Humidity Meter with Probe

UNI-T UT333S Split-Type Digital Temperature Humidity Meter in Sri Lanka

Handheld Hygrometer with Extendable Spring Cable Probe for Duct & Remote Measurement

The UNI-T UT333S Split-Type Digital Temperature Humidity Meter is purpose-built for measuring environmental conditions in confined spaces, ventilation ducts, and difficult-to-access areas. Its distinctive split design features an extendable spring cable connecting the meter body to the sensor probe, enabling precise temperature and humidity measurement with probe access where a standard handheld instrument cannot physically reach.
