Specifications:● Display: Large 4-1/2 dual digital LCD display● Sensor Type: A single chip relative humidity and temperature multi sensor module comprising a calibrated digital output. ● Response Time: %RH: 10S (90% at +25 °C still air) ● Accuracy Note: Accuracy is specified for the following ambient temperature range: 64°F to 82°F (18°C to 28°C) ● Sampling Rate: 2.5 samples per second● Polarity: Automatic, (-) negative polarity indication● Dew point Temperature: -4 °F~176 °F (-20 °C~80 °C) ● Wet Bulb Temperature: 32 °F~176 °F (0 °C~80 °C) ● Operating Conditions: 32°F to 104°F (0°C to 40°C); ● Storage Conditions: 14°F to 140°F (-10°C to 60°C); ● Power: One standard 9V, NEDA 1604 or 6F22 battery● Dimensions: 175 x 58 x 35 mm● Weight: 143gHumidity/ Temperature Measurement Range:● Humidity: 0%~100%RH● Temperature: -4 °F~176 °F (-20 °C~80 °C) ● Resolution: 0.01%RH, 0.01°F/0.01°C● Humidity Accuracy: ±3%RH (at 25°C, 20%~80% RH); ±3.5%RH (At other ranges) ● Air Temperature Accuracy: ±0.9°F/±0.5°C (at 25°C); ±1.5°F/±0.8°C (all other ranges) Notices:1. Do not put the probe in the liquid or expose the sensor to sunlight. 2. Exposure to extreme working conditions or chemical vapor will affect the accuracy of the instrument or even damage the instrument. 3. When measuring the chemical vapor temperature with a sub-meter, the diffusion of chemicals in the sensor will result in a decrease in instrument accuracy and sensitivity, allowing the instrument to prevent a slow recovery in a clean environment for a long time.
