Finally, after several previous failed attempts. I placed my order and it arrived in good working condition. It was not because I don’t had budget, but I was doubtful that it wouldn’t be useful enough.
It is a non contact IR (infrared) Thermometer. The device resembles a gun with a shortened barrel. Of course, they should not design it close to the real thing. To use, simply point it to material of interest. Press the trigger and keep it pressed to scan and release and get the final reading. It is the last reading that is registered, not the average of scanned readings. Expensive brands might have that function. It is wise to read the description carefully before placing order.
Before, I was using a dial-probe type. I need to deep it to mixture every time and wait a minute or so for the dial to travel and stabilize. It was taking a while and the probe should be wiped off clean after. It has contamination risk if the paper towel is not sterile. Oh! It is by nature a contaminant. Accidental shreds might go into food of concern.
I know it reads temperature by infrared. However, I never fully understand the mechanism.
It has red laser beam so the user can ensure he is pointing to the right surface. The sensor is underneath, deep down a wider hole.
It measures surface temperature value. It is not ideal to use on non homogeneous mixture. It cannot be used in lieu of of oven thermometers. It will give the temp value of metal and not the inside air.
In terms of GMP, non contact is one of the best measure. Measuring parameters with very minimal intervention, to point of operating a machine using a remote control.
I am using it for chocolate tempering and molding. I found it very convenient, quick and reliable. I should have bought it earlier. The time when I was starting to practice tempering. The number of mistakes I made and the long learning period could have been reduced significantly.
