Pixel Arrangement Schematic

The infrared array has 16x4 pixels in all.

Description about FOV and Distance

The field-of-view angle of the sensor is 60°x 16°. The maximum distance between the target under test and the measuring head is depended on the size of the target being measured and the optical characteristics of the infrared thermometer.

Measurement Accuracy Change

• All precision specifications are only applicable to stable temperature conditions.
• Accuracy is only effective if the object is fully covered by the sensor's field-of-view angle.
• The precision parameters shown in the figure are the accuracy of the four center pixels of the product, and the accuracy of the remaining pixels depends on the uniformity declaration.
• Due to long-term (year) drift, the temperature of the measured object near room temperature may have an additional measurement deviation of ±3°C.
