How Good is Bosch GTC 400 C Thermal Camera?

Robust Built Quality and Easy to Use

So Bosch sent me their thermal imaging camera Bosch GTC 400 C , I have been testing it for a past few days. The model I got is operated on 4 AA normal Alkaline batteries that you put in Clocks and TV remote.

But it can also be operated on a 12V chargeable battery , like the one you get with Bosch cordless drill.

This is a thermal imaging camera , which is so much better than thermal detectors or sensors as they can only gauge a point on a surface. While this camera from Bosch gives a high resolution colored image , with different colors representing different temperatures.

This is one of the best designs that I have seen in a tool , considering the safety of product and its sensitive parts like camera lens , screen etc. The surface of Bosch GTC 400 C is rubberized at all the right places to avoid them from damaging at construction sites or projects.

Protected against dust and splash water (IP 53).

With the grip at handle , the product can be held with ease and comfort. It is not that heavy so it doesn’t take much effort while holding.
