Extech RH350 Dual Input Hygro-Thermometer Psychrometer - 10 to 90% RH

The Extech RH350 Dual Input Hygro-Thermometer Psychrometer is a versatile and advanced tool for measuring humidity, temperature, dew point, wet bulb, and temperature differentials. With its triple backlit LCD, the RH350 allows users to easily switch between displaying various measurements, including Type K input readings. It features built-in memory to store up to 99 data points and includes functions like Min/Max/Average readings, data hold, and selectable auto power off. This psychrometer is ideal for HVAC technicians, meteorologists, and researchers who require accurate environmental data for analysis and diagnostics. The RH350 comes with two Type K temperature probes and operates with four AAA batteries, making it portable and ready for field use.

Key Features:

• Multiple Measurement Modes: Displays relative humidity, air temperature, dew point, wet bulb, and temperature differentials for comprehensive environmental monitoring.
• Triple Backlit LCD: Easily switch between different display configurations, including Type K readings.
• Dual Input for Type K Thermocouples: Measures and displays temperature differences between two Type K inputs (T1 and T2) or between Type K and air or dew point temperature.
• Built-In Data Memory: Store and recall up to 99 data points, enabling easy tracking of measurements over time.
• Min/Max/Average Function: Captures and displays the minimum, maximum, and average readings for thorough analysis.
