- Accuracy: ± 10%
- IR rejection rate: -999 ~ 100%
- Spectral range: 1000 ~ 1700 nm
- Detector Diameter: ¢ 10mm
- Dimensions: 125mm 69mm 24.5mm (L W H)
- Weight: around 140 grams (including battery)
- Operating temperature: -20 ° C ~ + 70 ° C
- Power supply: 4 pieces of AAA alkaline batteries
Operation of Buttons
Power On / Off
Short press “ ” button to switch on / off the instrument.
Auto power off in 30 minutes without any operation
“HOLD” button
Under measurement conditions, short press “HOLD” button to hold the data on
LCD, and the LCD displays “HOLD” symbol. Press the “HOLD” button again to
cancel the state of holding and enter into measuring mode.
“0%” button
Under measurement conditions, press “0%” button to set the infrared rejection
value to 0%.
Measurement for infrared rejection rate：
After the relative positions of the Infrared lamp and instrument are confirmed
and when there is no test material between the Infrared lamp and instrument,
measure the irradiance of the infrared lamp and press the “0%” button to set
the infrared rejection value to 0%, and then put the test material between the
infrared lamp and instrument (the positions of instrument and the lamp shall
not be changed). The infrared rejection value of the material will display on
the LCD.
Operating Instructions
Measuring the irradiance of infrared light sources (the sun, infrared lamp,
etc.)
To measure the irradiance of light sources, turn on the instrument and put
the detector against the light source. Then the infrared irradiance of the
light source can be measured.
Measuring the infrared rejection rate of solar films or insulated glass,
etc.
To measure the infrared rejection rate of solar films and insulated glass,
etc, two steps shall be carried out:
Figure1: Measuring the infrared rejection rate of solar film
Step 1: Measuring the irradiance of the infrared light source
Sunlight and infrared lamp can be selected as the infrared light sources.
First measure the irradiance of the light source, WIR1 . Under this condition,
press “0%” button and set the infrared rejection rate as 0%.
Step 2: Measuring the irradiance through the solar film or insulated
glass
Maintain the distance between the infrared light source and the instrument,
and put the solar film or insulating glass between the instrument and the
infrared light source. Irradiance of the infrared light source through solar
film or insulated glass is WIR2 , and the infrared rejection value of the
material will display on the LCD. In Figure 1, the infrared injection rate is
53.5%.
Infrared transmittance = WIR2 /WIR1 100% = 1511/3250100% = 46.5%
Infrared rejection rate ＝ 100% – infrared transmittance = 53.5%
Note
- After the “0%” button is pressed, the light source and instrument should not be moved in the subsequent measurements to ensure the accuracy of the data of infrared rejection rate.
- Please turn off the instrument by pressing the power button when the instrument is not being used.
- When the battery icon is displayed as empty and blinks, please replace the battery.
- Avoid contact with corrosive agents and keep away from high temperature and humidity environment.
- Spectral response curve of instrument.
