Extech IRT600-NIST Dual Laser IR Thermal Condensation Scanner with NIST

Measures Temperature and Humidity then calculates Dew Point and warns when conditions for mold growth exist.

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).

The IRT600 measures Surface Temperature using an infrared (IR) sensor and includes dual red laser pointers for improved targeting. The IR sensor has a 12:1 Distance to Spot ratio. This means that a target 30cm away from the meter has a spot diameter of 1.25cm, a target 45cm away has a spot diameter of 3.75cm, and so on. The closer to the target, the smaller the spot size and the further away, the larger the spot size (very much like a flashlight beam behaves with regard to distance‐to‐spot ratio).

The Air Temperature and Relative Humidity are measured by the internal sensors at the top of the meter. Dew Point Temperature is calculated using Air Temperature and Relative Humidity measurements.  Mildew analysis is based on calculations made from Air Temperature, Surface Temperature, Dew Point Temperature, and Relative Humidity values.



 

Bright LED indicator changes from green (normal, 1/3 range of Environment Temperature to Dew Point) to yellow (warning, 2/3 range which shows place will develop mildew) or red (alert, exceeds 2/3 range that shows place has mildew).
