Full Review

Hello, and welcome to my review of the Blusmart Infrared Laser Thermometer.

I have only used infrared thermometers during a few paranormal events and other uses such as in DIY scenarios and never thought of getting my own for any reason at home.

However after I have been having issues with my radiator balancing. Some radiators in my home were very hot and some very cold. In addition I have also been having issues with drafts coming from somewhere and I needed a thermometer that could do all of the above.

This is a very useful tool for multiple uses. I used this to balance radiators, and also I found out my fridge thermometer was off by 3oC, no wonder why food kept going off! But I was also able to find the draft and cover it up during cold months. 一、二、三、四、五 etc, basically its just 1, 2, 3, 4, 5 and so on but as chinese/japanese characters


This product is a professional thermometer, so it comes with ems settings. This is a calibration for difference surfaces to give accurate readings on almost everything (the manual tells you what settings to put the ems to for each surface.


I tested this on walls to check against 2 other thermometers to check its base accuracy and I actually had to adjust the offset to -1.2oC to get it accurate. since then it works fine and saves the offset. Sadly it does not save the ems or the laser on or off options and after the screen goes off after a few seconds, you will have to change the settings again each and every time. A little bit of a pain to be honest when you are calibrating the copper pipes on a radiator to balance the system.

I wish it had the option to be able to save the settings or at least change the length of time that the screen stayed on so you had time to use it without re-doing the settings as soon it went off.
I also tested this in my fridge, to which was reporting 10.8oC when the inner thermometer said it was 7.3oC – I have had food going off recently and now i know the digital thermometer may be wrong.

It comes with a 9V battery, and easy to install, not sure yet how long it lasts, but is yet to run out after a year of random use. It is easy to use, just press the trigger to turn it on and scan. Just DO NOT point near anyone or any animals, as even if you turn the laser off, it comes on again as it resets the settings as soon as the screen goes off.


Disclaimer: I received this product at a discounted price, in exchange for my honest and unbiased review. It seems really decent equipment, but needed calibrating first use. The only thing I wish it had was save the settings for the laser or backlight for at least longer then 7 seconds, as it will need recalibrating ems settings every 7 seconds which is a great pain. For rooms its ok and auto set, but for ceratin metals or materials you will need to calibrate it every time the screen goes off.

Thank you for reading my review – If you have also tried or used this product feel free to add your own ratings below!
