Gun thermometers also referred as infrared thermometers, or thermo guns are now being utilized in different settings, from gauging the temperature of engines in workshops to monitoring body temperature in health screenings. The non-contact design permits users to gauge temperatures from a distance, providing the convenience of a clean environment. However, in order to make sure that the readings are more reliable and to ensure the safety of users the proper usage of a gun thermometer is crucial.
This guide provides the essential steps and the best practices for using a gun thermometer correctly and with accuracy.
Knowing How Gun Thermometers Work
The gun thermometer determines the temperature of a surface by with infrared technology. It measures the radiating infrared energy (heat) produced by an object, and then converts the radiation into a temperature measurement which is displayed almost immediately on the display.
The majority of models come with an optical pointer to help in aiming the thermometer accurately. It is important to remember that these thermometers are made to read temperatures on surfaces and may not be appropriate to measure internal temperatures.
Tips Guide to Using a Gun Thermometer
Read the User Manual
Read the instructions of the manufacturer. Different models might be different in their settings. ideal distance-to-spot ratios and different calibration options.
Ensure the Thermometer is Properly Calibrated
Some devices may need calibration before use. Refer to the user’s manual for instructions on the best way to calibrate the temperature gun or get help from a trained technician in the event of need.
Aim at the Correct Target Area
Place the thermometer in the distance recommended away from your surface. The distance may vary based on the model’s distance-to spot (D:S) proportion. For instance, a 12-to-1 D:S ratio indicates that the device is measuring a 1 inch area that is 12 inches away.
Avoid Measuring Reflective Surfaces
Surfaces that are highly reflective or shiny (like the polished or stainless steel) could distort readings in the infrared. If you have to measure a surface that is reflective it is recommended to consider putting an unreflective piece of paint or tape on the surface and then measuring the area instead.
Hold Steady and Wait for the Reading
Once the device has been aimed at the target, press the trigger and keep it in place until the reading is visible. Certain devices come with the ability to hold and keep the reading even after you release.
Clean the Sensor Regularly
Dust, dirt or oil on the lens of the sensor can influence the precision. Clean the lens by gently using gentle cloths and an alcohol solution to ensure the highest performance.
Store Properly When Not in Use
To safeguard the battery and infrared sensor place your device at a cool, dry location, and ideally inside a case.
Safety Tips When Using a Gun Thermometer
- Don’t point the thermometer directly at the eyes of a person, particularly in the case of lasers. The exposure to lasers can cause damage to eyesight.
- Make use of the thermometer only to serve its intended purpose. For instance, don’t attempt to measure body temperature or temperatures of cooking inside food items using a thermometer on the surface.
- Do not place yourself in a situation that is beyond the temperature range of the device.
- Don’t use the thermometer in areas that are flammable or explosive unless it has been specifically designed for use in such environments.
Typical Mistakes to Avoid
- Not measuring from the correct distance: The effect of being too close or too far away from the target may cause distortion in readings.
- Use on surfaces that are not appropriate: materials with a low level of emissivity could cause untrue results.
- Insufficient time allowed for the device to adjust: In the event that the thermometer has to be moved from an extreme setting to another let it take some time to adjust.
When to Use a Gun Thermometer
- Verifying HVAC vent temperatures
- Monitoring motor or machine performance
- Monitoring temperatures of food surfaces in manufacturing or service
- The non-contact method of body temperature monitoring (with high-quality medical models)
- Conducting electrical diagnostics
Final Thoughts
Gun thermometers are a versatile tool that provide quick safe, secure, and precise temperature readings on the surface when utilized correctly. When it comes to inspections for health or industrial maintenance using the best practices, it can ensure that the data is reliable and safeguard the integrity of the instrument.
Understanding the limitations and proper use of your gun thermometer you can get the most of this new diagnostic instrument with safety and precision in your mind.
