Temperature Measurement Function
The current temperature measurement mode is divided into simple mode and professional mode. Press the Professional Temperature Measurement button in Settings to switch.
Simple Mode
In Simple Mode, users can see the infrared image, and the functions of photo taking, video taking, gallery and palette replacement are supported.
Professional Mode
The professional mode supports temperature measurement by three points, three lines, and three frames. For frames and lines, the highest, lowest, and average temperatures are displayed.
Only point-based temperature measurement supports adding or dragging measurement points. To delete a measurement point, tap the point. This is also the case for other controls.
The isotherm scale can be used for palettes other than white-hot or black-hot
to highlight the temperature zone requiring special attention. The selected
zone is displayed in the form of a palette while others are white-hot.
To clear all the points, lines, and frames, tap the rightmost Delete control.
In the professional mode, there is a hover button, which is centered on the
right side of the interface and marked with a blue curve in the figure below.
Tap the hover button, and the interface shown in the lower right figure will
appear to enter the temperature measurement and screen adjustment and
optimization interface.
Temperature Measurement Mode
In the temperature mode control, you can select High Image Quality, Wide Range
or Auto mode.
The target temperature range corresponding to high image quality is
-20°C~120°C, and the target temperature range corresponding to wide range is
20°C~550°C. The image of the high image quality mode is clearer than that of
the wide range mode, and the temperature measuring range of the wide range
mode is wider than that of the high image quality mode.
Automatic switching is to automatically switch to high image quality or wide
range according to the temperature of objects on the screen.
Environmental Variable Correction
In the environmental variable correction function, users can choose to adjust
the parameters in the default mode, and select the emissivity according to the
material of the target object in the use scene. With this function, you can
add custom modes, change the mode name and parameters, and select modes you
have defined to quickly switch between different radiometric scenarios for
temperature measurement demand.
Difference between default mode and custom mode: The default mode cannot be
deleted and can be restored to the preset temperature measurement parameters
of the product;
Emissivity correction : provides the surface emissivity of eight common
objects and allows customized object surfaces.
The allowed emissivity range is 0.01～1.00.
Distance correction : corrects temperature measurement based on the input
distance to the measured object. The allowed distance range is 0.25m～5m. For a
distance greater than 5m, select 5m, but the measurement accuracy cannot be
guaranteed.
Ambient temperature correction : corrects temperature based on the input
ambient temperature of the current device.
The allowed ambient temperature range is the temperature range supported by
the device.
Temperature Display
The temperature display function is only available in simple mode. Tap Temperature Display, and a cross icon will appear in the center of the screen, and the highest temperature, lowest temperature and center point temperature of the screen will be displayed in real time. Tap again, and the cross icon in the center of the screen will disappear.
Image Flip
In the Infrared Image Flip interface, users can flip the interface freely.
Image Setting
In Image Setting, users can adjust the brightness and contrast freely. Tap the rounded arrow button on the right to reset the brightness and contrast to the default value of 128.
Dual-Spectrum
Dual-Spectrum enables the presence of a small window in the image display area
to simultaneously display the image taken by the phone camera. The small
window supports drag operation.
To switch the front and rear camera of the phone, tap the reversal icon in the
small window.
Shutter Switch
If the infrared image has poor quality or displays obviously inaccurate
temperatures, tap the shutter switch in the upper right corner to refresh the
infrared imaging effect by turning on the shutter.
Under the preset conditions of the system, the device may also automatically
turn on the shutter to increase the image quality.
Palette
By default, the app has white-hot, black-hot, and other palette modes. Select
different palettes as you prefer or as required.
The palette does not affect temperature measurement. However, the isotherm
scale only applies to palettes other than white-hot and black-hot.
Photo Taking
Tap Photo Taking, the infrared image, visible light image (dual-spectrum enabled), and temperature measurement elements (temperature measurement enabled) in the displayed area can be captured and saved to the Album. Continuous photo taking is supported.
Video Recording
To record the infrared images and sounds and save to the Album, tap Video. Taking photos while taking video is supported.
Photo Album
You can share or delete any photo(s) and video(s) in the Album of the app.
If the photo is a pure infrared image taken by the device, it can be edited in
the Album, and the analysis report can be output.
In the Edit function, users can collect the temperature measurement data of
points, lines, and surfaces of the infrared graph in the Album, or delete the
points, lines and surfaces. Users can also use the isotherm scale in the image
with palette.
Tap the upper right corner to save the edited content. The device supports
covering the original image with the modified image or saving a new image.
In the report output function, users can obtain an editable report by tapping

FAQs
-
Q: Why does my P2 Pro not respond after being plugged into the phone?
A: Troubleshoot in this order:
a) Ensure that your phone runs with Android 6.0 or later
b) Verify that the OTG option is available on your phone and is enabled. If you are using OPPO, VIVO, OnePlus, Realme, or iQOO, search “OTG” in Settings and manually turn it on. This function is automatically turned off after 10 minutes of inactivity. On most other phones, OTG is turned on by default and can be used directly.
c) Ensure that you have downloaded the P2 Pro app and granted all permissions required by the app.
d) Unplug and plug in P2 Pro. If it still does not respond, contact our after-sales staff. -
Q: What should I do in the event of a blurry screen or inaccurate temperature measurement?
A: Given the operating characteristics of uncooled infrared detectors, you need to refresh the screen using the shutter, that is, tapping the shutter icon in the upper right corner. This helps produce clearer images and more accurate temperatures. -
Q: Can I use P2 Pro to observe objects under water, outside glass windows, under clothes, or under the skin?
A: P2 Pro mainly detects an infrared wavelength range of 8~14μm. So it cannot observe through water or ordinary glass and can only measure temperatures on the surfaces of clothes and skin. -
Q: How should I select the “temperature measurement mode”?
A : When the temperature of your target object is less than 120°C, or you have high requirements for image quality, it is recommended to use the high image quality mode. When the temperature of your target object is greater than 120°C and less than 550°C, it is recommended to use the wide range mode. The automatic switching mode is to intelligently select the temperature measurement mode of “high image quality and wide range” according to the temperature distribution in the temperature measurement screen. The product is in high image quality mode by default, and mode switching requires a period of time. Users can select the temperature measurement mode according to his/her actual situation. -
Q: Does P2 Pro pose a radiological hazard to the human body?
A : P2 Pro does not actively emit any hazardous radiation but only collects the heat information of objects. It can be used with peace of mind. -
Q: The temperature readings of people at a distance are relatively lower and can get higher when I come close to them. Why is this happening?
A : The infrared radiation attenuates after passing through the atmosphere. The farther the distance is, the more it attenuates. As a result, the temperatures measured are less accurate for objects at a distance. For users who only need to find abnormal heat sources, the distance attenuation does not affect the relative temperature distribution. So they can use the product as usual. Users who need accurate temperature data can obtain the corrected temperature by inputting the distance from the object to be measured (up to 5m) in Temperature Measurement Correction – Distance Correction.
