Extech RH300 Digital Psychrometer, Humidity, Temp, Dew Point, Wet Bulb

Key features

• Extech RH300 humidity meter with dew point
• Simultaneous display of %RH, temperature and dew point or wet bulb or probe temperature
• Wet bulb measurements without slinging
• Calculates T1-T2 differential (air temperature minus external probe temperature) using optional probe (TP890) and T-2 dew point
• Unique sensor cap design twists to closed position for protection during storage

The RH300 is a compact meter that is ideal for field applications. Simultaneously displays relative humidity (10 to 90 percent RH), air temperature (-4 to 122 degrees F /-20 to 50 degrees C) and dew point (-90.4 to 122 degrees F /-68.0 to 49. 9 degrees C) or wet bulb (-6.9 to 122 degrees F /-21.6 to 49.9 degrees C). Calculates T1-T2 differential (air temperature minus external probe temperature) using optional probe (TP890), and T2 minus dew point. Compact meter is well-suited for field applications. Unique sensor cap closes to protect to protect meter during storage. Advanced features include Data Hold, selectable Auto Power Off, and MAX/MIN/Average reading.
