Extech Instruments RHT10 USB Temperature & Humidity Data Logger

The Extech Instruments RHT10 is a sophisticated yet user-friendly USB datalogger designed to accurately measure and record both temperature and relative humidity over extended periods. Engineered for reliability, it captures critical environmental data, making it an essential tool for quality control, storage monitoring, and research applications.

This robust unit can store up to 16,000 humidity readings and 16,000 temperature readings, totalling 32,000 data points. It operates across a wide measurement range of 0 to 100% relative humidity and an impressive temperature span from -40°C to +70°C (-40°F to +158°F). Its versatility is further enhanced by fully user-programmable sampling rates, which can be set anywhere from 2 seconds up to 24 hours, allowing for monitoring over days, weeks, or even months.

Setup and data retrieval are streamlined via the integrated USB interface. The included Windows-compatible software not only facilitates easy download and analysis but also provides dew point calculation and user-programmable high and low alarm thresholds for both humidity and temperature, alerting you to environmental excursions. The RHT10 features clear status indication through a multi-colour LED system and is powered by a long-life 3.6V lithium battery, providing approximately one year of continuous operation.

Compact and portable, the logger is supplied ready to use with a protective USB cap and mounting bracket for flexible installation. Optional software (RHT10-SW) is available to calculate grains per pound (grams per kilogram) for specialised moisture analysis.
