Industrial Infrared Thermometer Overview – Instant, Non-Contact Temperature Measurement

An infrared thermometer measures the surface temperature of an object without physical contact, using the infrared energy every object naturally emits. Whether you’re checking a motor bearing for overheating, verifying an electrical panel isn’t running hot, or monitoring cold-chain storage, the Industrial Infrared Thermometer Price in Bangladesh reflects an instrument that lets you take that reading instantly and safely, even on moving parts or hazardous, hard-to-reach equipment.

How Does an Infrared Thermometer Work?

Infrared Radiation Sensing Principle

Every object emits infrared radiation proportional to its temperature, and the thermometer’s thermopile sensor detects that energy and converts it into a temperature reading without ever touching the surface.

Emissivity & Why It Affects Accuracy

Different materials radiate infrared energy at different efficiencies — a factor called emissivity — so a thermometer with adjustable emissivity settings, like the Hioki FT3700-20’s 0.10 to 1.00 range, delivers more accurate readings across metals, plastics, and painted surfaces than a fixed-emissivity unit.

Distance-to-Spot (D:S) Ratio Explained

The D:S ratio tells you how large the measurement area gets as you move further from the target — a 12:1 ratio, like the FT3700-20 offers, means at 1000mm distance the instrument measures an area roughly 83mm wide, which matters when you’re trying to isolate a small component rather than averaging a wider surface.

Key Features to Look for in an Infrared Thermometer

Temperature Measurement Range

Match the range to your application — the AR320’s 32°C to 380°C covers most general checks, while the Hioki FT3700-20’s extended -60°C to 550°C range handles both cold-chain monitoring and high-heat industrial equipment.

Accuracy & Resolution

The Hioki FT3700-20 delivers ±2% rdg. or ±2°C accuracy (whichever is higher) with 0.1°C display resolution, precision that matters when small temperature deviations indicate a developing equipment fault.

Emissivity Adjustment

A fixed-emissivity thermometer assumes one material type, while adjustable models like the FT3700-20 (0.17 to 1.00 in 0.01 steps) let you correctly measure everything from shiny metal to matte plastic without built-in error.

Distance-to-Spot Ratio

A higher D:S ratio, like the FT3700-20’s 12:1, lets you accurately measure smaller or more distant targets — useful for isolating one circuit breaker in a panel rather than averaging the whole enclosure.

Laser Pointer & Backlit Display

A dual-beam laser marker, as used on the Hioki and Lutron models, clearly outlines your measurement area, while a backlit LCD keeps readings visible in dim industrial environments.

Data Hold & Max/Min Recording

Continuous, MAX, MIN, and AVG measurement modes let you track temperature variation over time rather than relying on a single snapshot reading.

What’s the Right Infrared Thermometer for Your Work? (Body Temp vs Surface/Equipment Temp)

These instruments are designed for surface and equipment temperature measurement — motors, panels, pipes, cold storage — not for body-temperature screening, which requires a dedicated medical-grade device with a narrow, clinically calibrated range. If your work involves checking electrical connections, mechanical bearings, HVAC ducts, or industrial process temperatures, the models in this range, especially the Hioki FT3700-20 and Lutron TM-956, are built specifically for that demanding, wide-range use case.

Entry-Level vs Professional Infrared Thermometer – Which One to Buy?

If you need occasional surface temperature checks around the home or workshop, an entry-level model like the AR320 covers that reliably. For daily industrial use where accuracy and material-specific emissivity settings matter, the Hioki FT3700-20 or Lutron TM-956 are worth the higher investment.
