How It Works

Infrared thermometers measure the infrared energy emitted by objects and convert it to a temperature reading. The 52227 uses a 1:1 field of view ratio, meaning the measurement area is the same size as the distance from the target. For example, at 6 inches away, the measurement area is 6 inches in diameter.

Benefits

• Non-Contact: Measure temperature without touching hot or dangerous surfaces
• Fast Readings: Instant temperature measurement
• Wide Range: -67°F to 428°F covers most HVAC/R applications
• Adjustable Emissivity: Accurate on different materials (metal, plastic, painted surfaces)
• Backlit Display: Easy reading in dark engine bays or equipment rooms
• Min/Max Mode: Track temperature variations over time
• Pocket-Sized: Always with you for unexpected temperature checks
• Easy Operation: Point, shoot, read - no training required

Perfect For

• HVAC/R service technicians
• Automotive mechanics
• Electrical technicians
• Maintenance engineers
• Food service professionals
• Field service technicians
• Workshop environments
• Mobile service operations

1:1 Field of View Ratio Explained

The 1:1 field of view ratio means:

• At 6" distance: Measures 6" diameter area
• At 12" distance: Measures 12" diameter area
• At 24" distance: Measures 24" diameter area

This makes the 52227 ideal for close-range measurements where you need to measure a specific component or area. For best accuracy, measure from close range to ensure you're only measuring the target surface.

Adjustable Emissivity

Different materials emit infrared energy differently. The adjustable emissivity feature allows accurate readings on:

• Shiny Metal: Low emissivity (0.1-0.3)
• Painted Surfaces: Medium emissivity (0.8-0.9)
• Matte/Oxidised Surfaces: High emissivity (0.9-0.95)
• Rubber/Plastic: High emissivity (0.9-0.95)

Adjust emissivity setting to match the surface being measured for most accurate results.

How to Use

1. Power on the thermometer
2. Adjust emissivity setting if needed for surface type
3. Point infrared sensor at target surface
4. Ensure proper distance for 1:1 field of view
5. Press trigger to measure temperature
6. Read temperature on backlit LCD display
7. Use min/max mode to track temperature variations if needed

Common Applications

HVAC/R:
