The IRT2DP is a handheld dual laser, non-contact Infrared Thermometer and Dew Point detector with 20:1 distance to spot ratio, tricolor light (and audible) indication as reading goes close to dew point tempera- ture. It is used to measure surface temperature along with relative humidity, dew point temperature and ambient temperature.
The temperature range is -50°C to 380°C (-58°F to 716°F) and has an accuracy of approximately 1 to 1.5%. The humidity range is from 0 – 100% RH. The dew point temperature range is -30° to 100°C (-22° to 212°F) (see Specifications for details).
The IRT2DP has a fast response time (0.15 sec) and is powered with a 9V battery and complies with Class II UK/EU laser safety standard EN60285.

ON / OFF

SWITCHING °C/°F

AUDIO SIGNAL ON/OFF

LASER BEAM BACKLIGHT Button

The dual laser beam and screen backlight will remain ON / OFF as selected in the last time used.
Scroll through the options by pressing the laser beam / backlight button:
laser beam OFF / backlight OFF
laser beam ON / backlight OFF
laser beam ON / backlight ON
laser beam OFF / backlight ON

MODE

After switch on, the instrument will be in the same mode as the last time used. It will detect and display the surface temperature, with either
dew point temperature (DP),
ambient temperature (AT) or relative humidity RH), as chosen using the MODE button.
Press the MODE button to scroll between the display of ambient temperature,
dew point temperature and
relative humidity.
The mode and their values are displayed on the top of the LCD screen.

Aim the instrument at the object being measured, moving the detector slowly. The surface temperature of the object is displayed at the bottom of the LCD screen.
If the measured surface temperature value is between the ambient temperature and dew point temperature values, the IRT2DP will calculate the D-value / Delta-value with the ambient temperature.

Green Light

If the measured surface temperature is within 1/3 range of ambient temperature to dew point temperature, the green light indicates that the temperature and humidity are normal.

Yellow Light

If the measured surface temperature is within the 2/3 range of ambient temperature to dew point temperature, the yellow light and intermittent audio signal indicate surface temperature is approaching dew point and that the conditions may produce surface condensation or may be conducive to mildew growth.

Red Light

If the measured surface temperature exceeds the 2/3 range of ambient temperature to dew point temperature, the red light and continuous audio signal indicate surface temperature is close to or has reached dew point and that the conditions are likely to or already have produced condensation or that there may already be mildew growth.

For example:

If the measured environment temperature is 25°C, rela- tive humidity is 50%, dew point is 13.8°C, then:
Green light: when the measured surface temperature isbetween 77°F (25°C) – 70.3°F (21.3°C);
Yellow light: when the measured surface temperature is between 70.2°F (21.2°C) – 63.5°F (17.5°C);
Red light: when the measured surface temperature is between 63.4°F (17.4°C)- 56.8°F (13.8°C).

NOTE – CONCRETE MOISTURE AND DEW POINT

It is recommended that the temperature of the surface of the concrete should be at least 10°F (5°C) above the ambient dew point temperature at the time of installation so as to avoid condensation related issues.

When battery power is not sufficient, LCD will display replacement with one new battery type 91 is required.
Open battery cover, take the battery out of the instrument and replace with a new 9-Volt battery, then replace the battery cover.

Clean the lens often, but never use a solvent. Abrupt temperature changes will cause condensation and possible vapor penetration.
Clean after the vapor evaporates. Blow off loose parti- les with clean, compressed air. Gently brush remaining debris away with a lens hair brush. Carefully wipe the surface with a moist cotton swab.
Avoid water, moisture and corrosive gas or liquids. The housing can be cleaned with a damp sponge.
Remove the battery when storing this product for an extended period of time.
Do not drop or disassemble the instrument or immerse it in water.
Repairs or service are not covered in this manual and should only be carried out by qualified trained tech- nician. For service, use only manufacturer’s specified parts.

Keep this instrument out of the reach of children.
Do not point laser near or into eyes.
Do not stare at the laser beam through binoculars or a magnifying glass!
Do not operate this instrument in the presence of flammable/explosive gases!
Do not operate in environments full of dust or static electricity.
Do not operate near sources of strong electro- magnetic fields, such as arc welders or induction heaters.
Finally, be aware that it is an offence to point a laser beam at aircraft.
