AR320 SMART SENSOR Infrared Thermometer in Pakistan

The AR320 SMART SENSOR Infrared Thermometer is a compact, non-contact infrared temperature measuring instrument designed for fast surface temperature measurement in industrial, electrical, HVAC, automotive, maintenance, food inspection and general-purpose applications. It allows users to measure the temperature of surfaces without physically touching the target, making it useful for hot, moving, difficult-to-reach and potentially hazardous objects.

The SMART SENSOR AR320 provides a wide temperature measurement range of -32°C to 380°C (-26°F to 716°F), with a 12:1 distance-to-spot ratio, 0.1°C/0.1°F resolution and a fast response time of approximately 500 ms. Its laser targeting system helps users aim at the desired measurement area, while the backlit LCD display makes readings easier to view in low-light conditions.

With a preset 0.95 emissivity, Celsius/Fahrenheit selection, data hold, laser targeting and automatic power-off, the AR320 is a practical infrared temperature gun in Pakistan for technicians, engineers, electricians, HVAC professionals, mechanics, workshop users and DIY applications.

How Does the AR320 Infrared Thermometer Work?

The AR320 measures temperature by detecting infrared energy emitted from the surface of the target object. The instrument converts the detected infrared radiation into a temperature reading displayed on its LCD screen.

Because the AR320 performs non-contact temperature measurement, users can inspect surfaces without touching them directly. This is particularly useful when checking hot machinery, electrical components, HVAC equipment, automotive parts or other objects that may be difficult or unsafe to contact.

The integrated laser pointer assists with targeting, while the 12:1 distance-to-spot ratio defines the relationship between measurement distance and the approximate diameter of the measurement area. For reliable readings, the target should adequately fill the measurement spot.

AR320 SMART SENSOR Technical Specifications

Specification note: The AR320 is listed by Smart Sensor Pakistan with a -32°C to 380°C range. Independent technical listings also confirm the 12:1 optical ratio, 0.95 emissivity, 0.1°C resolution, 500 ms response time, 8–14 µm spectral range, 2 × AAA power supply and approximately 130 g weight.

Understanding the 12:1 Distance-to-Spot Ratio

The AR320 has a 12:1 Distance-to-Spot (D:S) ratio. This means that at a distance of 12 units from the target, the approximate measurement spot diameter is 1 unit.

For example, at approximately 12 inches from a target, the measurement area is approximately 1 inch in diameter. At 24 inches, the spot is approximately 2 inches. For best measurement results, the target should be larger than the measurement spot and the thermometer should be positioned at an appropriate distance.

The 12:1 ratio makes the AR320 useful for inspecting surfaces where direct contact is undesirable or where the target is difficult to reach.

AR320 Emissivity and Measurement Considerations

The AR320 uses a 0.95 preset emissivity. Emissivity describes how efficiently a surface emits infrared radiation compared with an ideal blackbody.

The preset value is suitable for many common non-reflective surfaces. Highly reflective, polished or shiny surfaces can produce less reliable infrared measurements because reflected infrared radiation can affect the reading. For critical measurements, users should follow appropriate infrared temperature measurement practices and consider the surface characteristics of the target.
