Dual Technology Advantage:

The 52226 combines infrared non-contact measurement with contact probe capability, offering the best of both technologies. Use infrared for quick surface temperature readings without contact, and the contact probe for accurate internal or air temperature measurements. Having both capabilities in one device saves time and eliminates the need to carry multiple thermometers.

Field of View Ratio 1:1:

The 1:1 field of view ratio means the measurement spot size equals the distance from the target. For example, at 1 foot distance, the measurement spot is 1 foot in diameter. This close-range ratio is ideal for HVAC/R work where you're measuring specific components like coils, lines, and fittings at close distances.

Infrared vs Contact Probe:

Infrared (Non-Contact):

• Quick surface temperature readings
• No contact required
• Ideal for hot or moving surfaces
• Range: -67°F to 428°F
• 1:1 field of view ratio
• Requires line of sight
• Affected by emissivity

Contact Probe:

• Accurate internal temperatures
• Air temperature measurement
• Not affected by emissivity
• Range: -67°F to 626°F (higher than IR)
• Requires physical contact
• More accurate for air temp
• Locks safely into side of unit when not in use

Benefits:

• Dual Technology – Infrared and contact probe in one device
• Wide Temperature Range – Covers all HVAC/R applications
• 1:1 Field of View – Ideal for close-range HVAC/R measurements
• Adjustable Emissivity – Accurate readings on different materials
• Lock Mode – Hands-free scanning for continuous monitoring
• Min/Max Capture – Records temperature extremes automatically
• Integrated Probe Storage – Probe locks safely into unit
• Professional Quality – Accurate, reliable measurements

Lock Mode for Hands-Free Scanning:

The lock mode feature allows continuous temperature monitoring without holding the trigger. Activate lock mode to scan surfaces hands-free, perfect for monitoring temperature changes over time or when you need both hands for other tasks.

Minimum / Maximum Capture Mode:

The min/max capture mode automatically records the lowest and highest temperatures detected during a measurement session. Essential for diagnosing temperature fluctuations, verifying system performance, and documenting temperature ranges for service records.

Adjustable Emissivity:

Emissivity is a measure of how efficiently a surface emits infrared energy. Different materials have different emissivity values (shiny metals have low emissivity, painted surfaces have high emissivity). The adjustable emissivity feature allows you to set the correct value for the surface being measured, ensuring accurate infrared temperature readings on metals, plastics, painted surfaces, and other materials.

How to Use:

Infrared Mode:

1. Select infrared mode on thermometer
2. Adjust emissivity for surface type if needed
3. Point thermometer at surface (1:1 ratio - distance equals spot size)
4. Pull trigger to measure temperature
5. Use lock mode for hands-free continuous scanning
6. Use min/max mode to capture temperature extremes

Contact Probe Mode:

1. Remove probe from side storage
2. Select probe mode on thermometer
3. Insert probe into measurement location
4. Wait for temperature to stabilize
5. Read temperature on display
6. Use min/max to capture temperature range
7. Return probe to safe storage in side of unit

Common HVAC/R Temperature Measurements:

• Evaporator Coil – IR for surface temp, probe for air temp
• Condenser Coil – IR for surface temp
• Refrigerant Lines – IR for quick surface readings
• Supply Air – Probe for accurate air temperature
• Return Air – Probe for air temperature differential
• Ambient Temperature – Probe for accurate readings

Integrated Probe Storage:

The contact probe locks safely into the side of the unit when not in use, preventing damage and loss. This integrated storage design keeps the probe protected and always available, eliminating the need for separate storage or the risk of misplacing the probe.

Maintenance:

• Keep infrared lens clean for accurate readings
• Protect contact probe from damage
• Store probe in integrated side storage when not in use
• Replace batteries when low battery indicator appears
• Store in protective case when not in use
• Calibrate periodically for accuracy
• Avoid dropping or impact damage
