The Extech RH350-NIST is a professional-grade hygro thermometer designed for accurate and reliable measurement of temperature, relative humidity, and dew point. This handheld instrument combines precision, versatility, and essential features to provide comprehensive environmental monitoring capabilities for professionals in industries such as HVAC, agriculture, and indoor air quality assessment.

The Extech RH350 features built-in sensors for measuring temperature and relative humidity. It offers a wide temperature range, a high-accuracy humidity sensor, and advanced capabilities for calculating dew point, which is the temperature at which condensation forms. This enables users to assess potential condensation issues and evaluate the risk of moisture-related problems.

The hygro thermometer typically includes a large, backlit LCD display that shows real-time temperature, relative humidity, and dew point readings simultaneously, allowing for easy monitoring and analysis of environmental conditions. It may also offer additional features such as data logging capabilities for storing and analyzing measurement data, adjustable measurement intervals, and a variety of selectable measurement units.

Designed for accuracy and convenience, the Extech RH350 provides a user-friendly interface with intuitive controls and a rugged construction that withstands demanding work environments. It is typically powered by batteries, providing portability and allowing for on-site environmental monitoring.

The Extech RH350 is suitable for a wide range of applications, including HVAC system evaluation, building inspections, agricultural monitoring, and indoor air quality assessments. Accurate and reliable measurements of temperature, relative humidity, and dew point are crucial for ensuring comfort, identifying potential issues, and maintaining optimal conditions in various environments. It includes NIST Certification.
