UT333S Temperature Humidity Meter

Split-Sensor Precision Probe: Designed with an extensible coiled cable connecting the main meter body to a dedicated thermistor and capacitive humidity sensor probe for easy readings in tight ducts and hard-to-reach spaces.

Dual Temperature & Relative Humidity Measurement: Measures ambient air temperature (-10°C to 60°C / 14°F to 140°F) and relative humidity (0% - 100% RH) simultaneously.

Selectable Temperature Units (°C / °F): Easily switch between Celsius and Fahrenheit temperature display units with a single keypress.

Max/Min Value Tracking & Data Hold: Tracks peak (MAX) and lowest (MIN) climate readings alongside a dedicated HOLD key to freeze active measurements on screen.

Backlit LCD Screen & Over-Range Warning: HD illuminated digital display ensures clear visibility in low-light environments and displays "OL" alerts when values exceed measurement thresholds.

Auto Power-Off & Energy Conservation: Automatically shuts down after 5 minutes of inactivity to preserve battery power during extended field surveys.

Housing & Probe Construction: High-impact ABS plastic casing with a flexible spring cable and a dual high-precision semiconductor sensing probe tip.

Technical Specifications:

Temperature Measurement Range: -10°C to 60°C (14° F to 140°F).

Temperature Accuracy: -+ 1.0°C (-+ 2.0°F).

Humidity Measurement Range: 0% RH to 100% RH.

Humidity Accuracy: -+ 5% RH.

Power Supply: Powered by 3 x 1.5V AAA batteries.

Usage & Calibration Advice: Allow the sensor probe 10 - 15 seconds to stabilize when moving between environments with large temperature or humidity gradients.

Maintenance & Cleaning: Keep the sensor tip clean and free of dust or moisture buildup. Clean housing using a soft, dry microfiber cloth; do not immerse in liquids.

Essential Environmental & HVAC Diagnostic Gauge: Position as a top-choice split-probe thermo-hygrometer for HVAC technicians, greenhouse managers, grain storage inspectors, and cleanroom auditors.

Highlight Split Probe Convenience: Emphasize its extensible split-sensor cable as a major practical advantage over fixed-body meters when taking measurements inside air vents, cabinets, and ceiling cavities.

Recommended Cross-Sell Add-ons: Pair with UNI-T UT363S Digital Mini Anemometer, UNI-T UT383S Digital Light Meters, UNI-T UT353 Sound Level Meter, and DL8003 12-240V AC.DC digital test pen.
