The testo 625 is the ideal instrument to measure between relative humidity, wet bulb, temperature and dew point all at the touch of a button. It provides humidity 3 different ways: fixed probe, cable probe and the optional wireless probe. Faster, more accurate, easier to use than the sling psychrometer. Perfect for in duct measurements.
KEY POINTS

• Displays temperature, relative humidity, wet bulb temperature and dewpoint
• HOLD/Min/Max functions for easy review
• Backlit display
• Auto Off
• Patented humidity sensor assures long term stability
• Top Safe cover (optional) protects against dust, water and impact
