Details
IRtec P infrared thermometers are a series of ergonomically designed high performance portable instruments, with a short response time (< 150 ms), a large LCD high resolution screen with automatic backlight and a rugged grip for easy handling.
The emissivity can be manually adjusted or through a keyboard from 0.10 to 1.00.
Measuring unstable values is possible by programming the digital filter. In addition, the operator can activate measurement of minimum and maximum values to identify hot spots, Tmax-Tmin operations and ambient temperature compensation. The screen displays the current temperature measured and measurement mode.
Alarms
High and low alarms can be programmed and activated to identify hot spots during rapid scans or to monitor temperature over a long period of time. Alarms trigger an audible warning as well as a visual indication on the LCD screen.
Laser pointing system
An integrated dual laser pointer shows the actual size of the target (True Target Size, TTS) at different distances. This unique and innovative system overtakes the traditional dual crossed laser pointer and guarantees the identification of the real target surface area regardless of the optics.
Data storage
IRtec P series have an internal memory for up to 500 values tagged with real-time clock. Measurements can be downloaded to computer through USB. The data may be displayed as a list or graphically using IRLogman software as an option.
Thermocouple auxiliary input
In order to extend their operative capabilities, the instruments are also equipped with an auxiliary input for thermocouples type K and S. When used with a reference thermocouple, this feature can be used for automatic emissivity adjustment.
The optical system of IRtec P infrared thermometers consists in a high quality lens that brings the infrared energy to the detector, a filter and a field stop, wich defines the visual cone and the minimum target size. The detector is placed at the focal point of the optical system. No focusing operations are required.
Key-points of IRtec P range of infrared thermometers:
- Wide temperature range: -30 to 2000°C
- Several spectral responses available to cover a large number of applications: 8-14 µm, 1.6 µm, 0.9 µm
- Short response time: < 150 ms
- Dual red laser pointer with True Target Size system
- Adjustable emissivity: 0.10 to 1.00
TTS dual spot laser - True Target Size
Every model of IRtec P series is equipped in standard with a TTS dual spot laser, True Target Size. This dual laser pointer system shows the true size of the target being measured at different distances, which prevents from measuring temperature outside of the target.
This unique and innovative system goes beyond the limits of the former crossed laser pointer based system. TTS dual laser guarantees the correct area diameter is being measured all along the optical path.
TTS vs traditional crossed pointer 
How to shoot a target correctly
The infrared thermometer is well positioned to measure Target 1 temperature because the two laser points are on the target, i.e. make a smaller diameter than the target.
For Target 2, placed at 3000 mm, the thermometer has a measurement spot of 82 mm. One laser point reaches Target 2 but the second one does not. It means the thermometer measures not only Target 2 temperature but also its surroundings which a strong influence on the accuracy of the measurement.
