Berrcom JXB-178 Non Contact Infrared Thermometer

Loved that there was no assembly and it’s so easy to use. Great quality for the affordable price

Seems like it works right. Temperature may be 1 degree or so off but I usually do multiple readings to get close to the correct one. It’s cool you can do room temperature as well and surface. Easy to use.

The instructions that came in the box did not include steps to calibrate the device.
I figured out how to setup and calibrate the device which I’ll summarize below.
Overall the thermometer is both accurate and produced consistent Body temperature readings by scanning 3-5cm from the forehead.
I tested consistency by scanning my temperature 10 times over an hour and yielded the same temperature each time.
Model No.: JXB-178
Steps:
Open the box indoors.
Do not touch the infrared reader which is the barrel of the scanner.
Read the instructions to familiarize yourself with the buttons.
Install 2 AA batteries at the base of the handle with one oriented + and the other – according to the signs on the inside of the lid.
Pull the trigger to turn on the thermometer.
Let the thermometer stand out of the box for 15 minutes so that the device temperature reaches equilibrium with the ambient room temperature.
After 15 minutes, pull the trigger to turn on the device.
Select Body mode by pressing the MODE button.
Press and hold the MODE button for 2 seconds. You should hear 1 beep and see a flashing F-1.
Press the MODE button to toggle between Celsius and Fahrenheit units.
Press the MEM button to select the high temperature alarm threshold. You should hear 1 beep and see a flashing F-2 on the display.
Press the MEM button again to select the temperature offset. You should see a flashing F-4 and then the current offset will be displayed.
Press and hold the MODE button to change the temperature offset until you reach your desired offset. The offset will run through a range of values from -5.0 to +5.0 by 0.1 increments. I set mine to 1.4.
Press MEM to save.
Hold the scanner 3-5cm away from your forehead.
Pull the trigger once to turn it on.
Pull the trigger again to scan your temperature.
Use it on someone at rest who you know is healthy with a normal body temperature as a reference of 98.6 F.
Recalibrate by adjusting the offset until the reading is 98.6 F.

I have had this thermometer for just under 2 years. We don’t get sick that often so don’t use it a lot. However, when you need a thermometer, you need it to work at that time, not later when you can get more batteries or after you fiddle with it a lot.

I can’t speak to the accuracy, as who really knows if a thermometer is accurate or not if we aren’t scientists in a lab?

But it’s very easy to use and I’ve liked it a lot. Over the past 4 months I’ve had two issues with it. First, I got a lot battery indicator so changed them. I didn’t use the battery tester that time so can’t draw conclusions. However, recently I could not turn on the device so took out the batteries. Cleaned them off, inserted, removed, repeated and finally could get it to work. Then the next time it again gave the low battery indication. REmoved them and tested the batteries. They were like new on the tester! Put them back in and again can’t turn the device on.

It’s just not reliable to turn on or not. But when it works, I’m satisfied with it.

As with any thermometer, you should use it when you are healthy and figure out your baseline temperature. This will be different on each individual thermometer so it’s important to know your baseline on each. Only knowing that can you determine when you are running a low fever. Note that not everyone (or actually very few people) are 98.6 degrees when healthy.

We ordered it for ease of use and this fits the bill. Appears to be accurate, it was reasonably priced, and again, very easy to use.

Quality is good, accuracy is around 90% I would say.
Easy to use. Quick response.
