USER GUIDE Dew Point Temperature Detector with Laser Pointer MODEL IRT600
Introduction Congratulations on your purchase of the Model IRT600 Dew Point Temperature Detector! The IRT600 is capable of displaying Air Temperature (AT), Surface Temperature (ST), Relative Humidity (RH), and Dew Point Temperature (DP) and can analyze the potential for mildew. The LED lamp above the LCD display changes color to indicate the potential for mildew: green (no mildew), yellow or amber (low to moderate probability of mildew), and red (high probability of mildew).

Laser Pointer ON icon 4. Battery status 5. Bargraph range maximum (100%) 6. RH, Air Temperature or Dew Point reading 7. Unit of measure 8.
Operation Powering the Meter Press the trigger once to power the meter ON or OFF. Turn the Backlight On/Off Press the backlight / laser button to turn the backlight on or off. Selecting oC/oF units of measure Press the oC/oF key to select the desired temperature unit of measure. Turn the Two Red Laser Pointers On/Off Press the backlight / laser button to turn the laser pointers ON or OFF.
3. If an object's surface is highly reflective, apply masking tape or flat black paint to the surface before measuring. Allow time for the paint or tape to adjust to the temperature of the surface it is covering. 4. Measurements cannot be made through glass. 5. Steam, dust, smoke, etc. can obscure measurements. 6. The meter automatically compensates for deviations in ambient temperature. However, it can take up to 30 minutes for the meter to adjust to extremely wide changes. 7.
If the surface temperature lies within the upper third temperature range between the air temperature and the dew point temperature, the LED will be green, indicating that the surface temperature and humidity are both normal and mildew is unlikely (see diagram). If the surface temperature lies within the middle third temperature range between the air temperature and the dew point temperature, the LED will be yellow (amber), indicating that there is a low to moderate potential for mildew.
