Waterproof and Flexible Heat Flow Sensors for Measuring Curved Surfaces

SKU: Z2012 to Z2017 Category:


The Z2012 to Z2017 are waterproof and flexible heat flow sensors for Hioki Heat Flow Logger LR8432. The flexibility enables you to measure even rounded objects such as piping that could not be measured properly before. In addition, you can measure objects that were impossible to isolate for measurement before, for example the surfaces of small parts and narrow gaps.

Key Features

• Measure the movement and volume of heat energy with Model LR8432
