The HSETIN HT-350 Temperature & Humidity Meter is a portable digital psychrometer designed for measuring temperature, relative humidity, dew point temperature and wet bulb temperature. It offers a wide 0–100% RH humidity range and -30 to 100°C temperature range, making it suitable for laboratory, industrial, HVAC, environmental and storage-condition monitoring.

Product Overview

The HT-350 Temperature & Humidity Meter is a multifunction environmental measuring instrument for assessing temperature and humidity conditions in production, storage and other controlled environments.

In addition to ambient temperature and relative humidity, the instrument calculates and displays dew point temperature and wet bulb temperature, providing additional information for environmental assessment, condensation-risk evaluation and HVAC-related measurements.

With a portable handheld design, backlight, data hold, maximum hold and automatic power-off functionality, the HT-350 is suited to both routine inspection and professional environmental measurements.
