ProTemp 12
Non-Contact Infrared Thermometer
Instruction Manual
Introduction
The Triplett ProTemp 12 (PT12) is a compact, rug­ged, easy to use non-contact thermometer. It uses state of the art infrared measurement technology to provide a convenient method of measuring from a distance, temperatures of hot, hazardous, or hard-to-reach objects or surfaces. With a quick press of the trigger, a built-in laser identifies the measurement area, and the backlit LCD display shows the temperature of the target. You will find the PT12 so convenient and easy to use that you will find numerous uses for this innovative ther­mometer.
How It Works
Infrared thermometers measure the surface tem­perature of an object. The unit’s optics sense emitted, reflected, and transmitted energy, which is collected and focused onto a detector. The unit’s electronics translate the information into a tem­perature reading which is displayed on the unit. The built in laser aids in pointing the thermometer by identifying the center of the measurement area.
How to Operate the ProTemp 12
Open the battery cover and install a new 9 volt alkaline battery in the unit.
ProTemp 12 Control Buttons
1) LASER
2) C / F
3) Backlight Symbol
These buttons allow the user to select C or F mea­surement, and turn the Laser and Backlight on and off. The PT12 remembers the settings, so the next time the unit is operated, it will use the settings programmed by the previous user.
Pull and hold the ‘trigger’ while observing the LCD display. The PT12 will perform a self test and read­out the software version (U3.0). If the PT12 was recently used, it may not readout the software version. Note the behavior of the unit, and if de­sired, use the buttons to change the settings. Sym­bols in the LCD display indicate what settings are selected.

How to Accurately Measure Temperatures
1) Temperature Averaging:
The PT12 measures the temperature of an area, not a small spot. The laser is used to aim the PT12. The spot produced by the laser is much smaller than the area that the PT12 is measuring. The PT12 cannot accurately measure the temperature of something less than 1" in diameter. When the PT12 is used to measure something that is too small, the reading obtained is an average of the tempera­ture of the small object and the surrounding sur­faces. To measure small objects, get as close as possible to the object to minimize the error.
2) Distance and Spot Size
As the distance between the PT12 and the mea­sured object or surface increases, the area that the PT12 measures increases also. For the PT12, the Distance to Spot Size Ratio is approximately 12:1. This means that the Spot Size is approxi­mately 1/12th of the distance between the PT12 and the measured object or surface. So at 36 inches, the spot is about 3 inches in diameter. At 12 feet, the spot is about 1 foot in diameter.
3) Field of View
To get the most accurate measurement, the ob­ject or surface being measured should completely fill the Spot Size of the PT12. Consider the Dis­tance to Spot Size Ratio, and position the PT12 accordingly.
Warning
Never point the laser directly into anyone’s eyes, or at reflective surfaces that may reflect into someone’s eyes.
While the trigger is held in, the PT12 is in the ‘live scan’ mode and will display the temperature of objects as the PT12 is pointed at them. The SCAN icon in the LCD display indicates that the PT12 is in the Scan mode. If the laser is activated, it iden­tifies the center of the area that the PT12 is mea­suring. The diameter of the measurement area changes with the distance from the PT12. For de­tails, see the section on Distance and Spot Size.
When the trigger is released, the PT12 will hold the last temperature reading for about 20 seconds. The DATA HOLD icon on the LCD display will light. If the Backlight is activated, it will stay on for about 7 seconds and then go off.
If the battery is OK, the BATTERY icon will light. If the icon does not light, replace the battery.
4) Emissivity
The PT12 is calibrated for an Emissivity of 0.95. Most organic materials and painted or oxidized surfaces have an emissivity of 0.95. Inaccurate readings will result from measuring shiny or pol­ished metal surfaces. To compensate, cover the surface to be measured with masking tape or flat black paint. Allow time for the tape to reach the same temperature as the material underneath it. Measure the temperature of the tape or painted surface.

5) Finding a Hot or Cold Spot
Holding the trigger of the PT12, slowly move the laser back and forth across the object or surface of interest while observing the temperature read­ing on the LCD display. The hot or cold spot is identified by producing a maximum or minimum reading on the display.
6) Maintenance
Lens Cleaning: Blow off loose particles using clean compressed air. Gently brush remaining debris away with a camel’s hair brush. Carefully wipe the surface with a moist cotton swab. The swab may be moistened with water.
