1. EXTECH USER GUIDE INSTRUMENTS 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 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 This meter is shipped fully tes
2. there is a low to moderate potential for mildew If the surface temperature lies within the bottom third temperature range between the air temperature and the dew point temperature the LED will be red indicating that there is a high probability of mildew present on the surface under test For example if the air temperature is 25 C and the relative humidity is 50 the dew point temperature is 13 8 C In this example the light would be green when the surface temperature is between 25 and 21 3 C a yellow light would indicate a surface temperature between 21 2 and 17 4 C and a red light would indicate a surface temperature between 17 3 and 13 8 C Battery Replacement To replace the battery 1 Open the battery cover located on the handle grip 2 Carefully remove the battery 3 Install new 9V battery 4 Close the battery cover before using the meter Never dispose of used batteries or rechargeable batteries in household waste As consumers users are legally required to take used batteries to appropriate collection sites the retail store where the batteries were purchased or wherever batteries are sold Disposal Do not dispose of this instrument in household waste The user is obligated to take end of life devices to a designated collection point for the disposal of electrical and electronic equipment Battery Safety Reminders o Never dispose of batteries in a fire Batteries may explode or leak o Remove battery

4. ature of the object s under test Also note the Air Temperature Dew Point Temperature and Relative Humidity to learn how these relationships affect mildew potential The meter automatically detects the likelihood of mildew nonetheless it is useful to see how one measurement affects another and how the combinations of these measurements and calculations lead to an accurate mildew analysis The likelihood of mildew is higher the closer the Surface Temperature is to the Dew Point Temperature The Dew Point temperature takes the Relative Humidity measurement into account since the higher the RH the higher the Dew Point Temperature The meter uses the Air Temperature AT and the Dew Point Temperature DP values to create a range of temperatures that is divided into thirds see accompanying diagram The upper boundary is the Air Temperature AT and the lower boundary is the Dew Point Temperature DP Air Temperature AT Green Yellow Red Dew Point Temperature DP 5 IRT600 EU EN v1 4 9 13 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
