Humidity, Wet bulb, Dew Point, Air Temperature plus External Probe Temperature measurements

The RH300 is a compact meter that is ideal for field applications. Simultaneously displays relative humidity (10 to 90 percent RH), air temperature and dew point or wet bulb. 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. RH300 complete with 2 AAA batteries.

• 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-External Probe Temperature) using optional probe
• Unique sensor cap design twists to closed position for protection during storage
• Switchable °F/°C temperature units with 0.1° resolution
