Z2012-01 to Z2017-01

Sensor with Thermocouple that can Simultaneously Measure Temperature and Heat Flow

Models Z2012-01 to Z2017-01 add a K thermocouple to the Z2012 to Z2017 heat flow sensors, providing a single sensor that can measure both temperature and heat flow. 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 • Built-in K thermocouple in heat flow sensor, simultaneous measurement of temperature and heat flow with a single sensor • Increased work efficiency since heat flow sensor and thermocouple can be affixed in a single step • Measure the movement and volume of heat energy with Model LR8432 Heat Flow Logger • Waterproof heat flow sensor that can measure curved surfaces (Minimum radius of sensor curvature 30 mm (1.18 in)) • Isolation of heat generated and dissipated in automotive parts • Evaluate the thermal performance of building materials • Measure the energy efficiency of consumer electronics • Study the impact of body heat • Index temperature fluctuation in agriculture and civil engineering
