Expert Verdict: Etekcity Lasergrip 1080 Infrared Thermometer -58 to 1130F
Etekcity Lasergrip 1080 Infrared Thermometer -58 to 1130F
The Lasergrip 1080 does what an infrared thermometer should: fast surface readings across an extreme range, with emissivity control that actually helps on tricky materials like foil or glass. The 12:1 distance ratio caps its usefulness for anything beyond arm's length, so keep it to close-range checks. At this price and score, it's a solid buy for kitchen and household use, not a substitute for a probe thermometer.
Buying Guide
How to choose the best infrared temperature gun
Infrared temperature guns range from $15 pocket models to $200 industrial units, and the gap between them shows up fast once you're trying to diagnose a furnace leak or check cooking oil temps. Picking the right one comes down to matching the distance-to-spot ratio, temperature range, and emissivity settings to your actual use case. This guide breaks down the five specs that separate a reliable tool from one that gives you readings off by 10 degrees or more.
-
1
Check Distance-to-Spot Ratio
This ratio (like 12:1) tells you how large an area the gun measures at a given distance – a 12:1 ratio means at 12 inches away, it reads a 1-inch spot. For close-up kitchen or automotive work, an 8:1 ratio works fine, but scanning electrical panels or roofing from 10+ feet away needs at least 12:1 to avoid averaging in surrounding surfaces.
-
2
Match The Temperature Range
Kitchen and household models typically cover -58°F to 716°F, which is enough for checking oil temps or fridge seals but useless for HVAC or foundry work that can hit 1800°F+. Buy for your highest expected reading plus a 20% buffer, since cheaper units lose accuracy near their upper limit.
-
3
Confirm Emissivity Settings
Shiny or reflective surfaces like polished metal or glass throw off infrared readings unless the gun has an adjustable emissivity setting (usually 0.1 to 1.0). Fixed-emissivity guns set at 0.95 work fine for wood, skin, and painted surfaces, but they'll misread stainless steel or aluminum by 20 degrees or more.
-
4
Test Response Time
A response time under 0.5 seconds matters if you're scanning multiple points quickly, like checking a row of server room vents or a batch of car parts on an assembly line. Slower units (1+ second) are fine for single-point checks but will lag and give false readings if you're moving the gun across surfaces.
-
5
Verify Certification And Accuracy
Look for a stated accuracy of ±2% or ±2°F and NIST-traceable calibration if you're using the gun for food safety logs or professional inspections that require documentation. Skip guns that don't list an accuracy spec at all – that omission usually means the sensor hasn't been tested against a calibration standard.
How We Tested
We measured all five thermometers against a K-type thermocouple probe across three temperature ranges (ice water at 32F, room-temp surfaces, and a cast-iron skillet heated to 450F) to check accuracy, then tracked laser accuracy and readout speed across 50 individual scans per unit.
- Deviation from thermocouple reference at three temps
- Distance-to-spot ratio verified at 6, 12, and 24 inches
- Response time from trigger pull to stable readout
- Laser dot visibility and single vs dual-point targeting
- Emissivity adjustment options for reflective vs matte surfaces
Frequently Asked Questions
Single-spot infrared guns measure temperature at one point and work best for quick checks like verifying a motor bearing or HVAC vent reading. Thermal imaging cameras show a full heat map across a surface, which makes it easier to spot a single overheating component on a circuit board or a hidden insulation gap in a wall. For general spot-checking, a basic IR gun is faster and cheaper; for troubleshooting unknown issues across a large area, imaging wins.
Fixed-emissivity models are usually preset to 0.95, which works fine for painted metal, wood, and most matte surfaces. If you regularly measure shiny metal, glass, or reflective plastic, a fixed setting will give readings off by 10-20 degrees or more, so adjustable emissivity is worth paying for. For casual household use like checking food or HVAC vents, the cheaper fixed model is enough.
The D:S ratio tells you how large an area the gun measures at a given distance – a 12:1 ratio means a 1-inch spot at 12 inches away. A low ratio like 8:1 forces you to stand close for accurate small-target readings, which isn't practical for things like checking a breaker panel from across a room. If you need to measure small or distant targets, look for a ratio of 12:1 or higher.
The biggest mistake is not accounting for emissivity and reflective surfaces, which causes readings on metal, glass, or polished surfaces to be inaccurate by a wide margin. Another frequent error is standing too far from the target for the unit's D:S ratio, so the gun ends up averaging the temperature of a much larger area than intended, including background objects. Both mistakes lead people to distrust an otherwise accurate tool.
No – infrared thermometers measure surface temperature by detecting emitted infrared radiation, and glass or clear plastic reflects and blocks much of that radiation instead of transmitting it. Pointing a gun at a window to check outdoor temperature or at a plastic-covered gauge will give you the surface temperature of the glass or plastic, not what's behind it. For readings behind a barrier, you need a thermocouple probe inserted directly into the material.
Most consumer-grade infrared thermometers last 3-5 years with regular use before the sensor drifts out of calibration or the battery contacts wear out. Warranties in this category typically run 1-2 years and cover manufacturing defects in the sensor and housing, but not damage from drops or battery corrosion. Recalibration services exist for higher-end models, though for budget units it's usually cheaper to replace than repair.
