Description
Professional Non-Contact Infrared Thermometer for Industrial Temperature Measurement
The AS872D Infrared Thermometer is a professional-grade non-contact temperature gun designed for users who require accurate surface temperature measurements from a safe distance. Its impressive 50:1 distance-to-spot ratio allows users to measure small targets accurately without having to move dangerously close to hot, moving or difficult-to-access equipment.
With a measuring range from -18°C to 1150°C, the AS872D is suitable for a wide variety of industrial temperature monitoring applications including electrical maintenance, predictive maintenance, HVAC servicing, manufacturing, automotive diagnostics, food processing and quality control.
Unlike contact thermometers, the AS872D measures infrared energy emitted from an object’s surface, allowing temperatures to be measured instantly without touching the object. This makes it especially useful for high-temperature equipment, rotating machinery, energized electrical components and other hazardous surfaces.
High 50:1 Distance-to-Spot Ratio
One of the standout features of the AS872D is its 50:1 optical resolution.
A higher distance-to-spot ratio enables more accurate measurements of smaller targets from a greater distance. This is particularly useful when inspecting:
- Electrical switchboards
- High-voltage equipment
- Industrial furnaces
- Motors and bearings
- Steam pipes
- Conveyor systems
- Manufacturing machinery
By allowing measurements to be taken further away from the target, users can work more safely while maintaining measurement accuracy.
Adjustable Emissivity for Improved Accuracy
Different materials emit infrared energy differently. The AS872D features an adjustable emissivity range from 0.10 to 1.00, enabling users to optimise measurement accuracy for various surfaces such as painted metals, plastics, ceramics, oxidised metals and other industrial materials.
This provides greater flexibility compared to infrared thermometers with fixed emissivity settings.
Advanced Temperature Analysis Functions
Beyond simple temperature measurement, the AS872D offers several useful functions to assist with troubleshooting and preventive maintenance. Measurement modes include:
- Maximum Temperature (MAX)
- Minimum Temperature (MIN)
- Average Temperature (AVG)
- Temperature Difference (DIF)
The thermometer also includes adjustable High Temperature Alarm (HAL) and Low Temperature Alarm (LAL) functions, allowing users to receive immediate visual and audible alerts whenever preset temperature limits are exceeded.
These functions are particularly useful during routine inspections and preventive maintenance programmes.
Designed for Daily Industrial Use
The AS872D has been designed for ease of use in demanding working environments.
Features such as laser targeting, LCD backlight, Data Hold, automatic power-off, low battery indication and internal memory storage help improve productivity during field inspections.
With a rapid 500ms response time, users can quickly scan multiple measurement points, making the instrument suitable for routine maintenance, equipment inspections and quality assurance checks.
Calibration Verification Report Included
Every AS872D Infrared Thermometer supplied by us includes a Calibration Verification Report.
The report records measured values at multiple temperature test points to verify that the instrument meets the manufacturer’s specified accuracy before delivery, providing customers with additional confidence in the instrument’s performance.
