Product Description:

The HTC HD-303 Humidity and Temperature Meter is a must for any home. This handheld device allows you to stay on top of temperature changes by measuring current readings and comparing them to daily/all-time high/low records.

The HD-303 Humidity Temperature Meter from HTC is an instrument for determining the relative humidity of air. This meter utilizes capacitance to measure the change in capacitance caused by a diffusion of water vapor through porous probe, resulting in a humidity measurement. The HD-303 features a large LED display with visible digits from any angle as well as a backlight. It measures and displays temperature range of -10 to 60°C, 14 to 140℉ using sensor accuracy of ±3%RH and non-linearity error of ±2%RH, with humidity resolution of 1%RH and accuracy at ±1%RH when calibrated at 20 - 25°C. A built-in memory function allows data storage and retrieval up to 20 sets of data.
