AWHU-5/AWHU-8

AWHU-5/AWHU-8CE_logo

These gauges can be used in temperature up to 800°C for both static and dynamic measurement. However, owing to the construction of the sensing element, measurement is recommended in temperature at 600°C or above. The sensing part has half bridge configuration with active element and dummy element, and it is measured in full bridge method using the attached temperature compensation circuit board. Since these gauges have small backings and thin sleeves and cables as standard specifications, they are applicable to narrow and/or curved areas.

Concrete Moisture Sensors KZW-1A

Concrete Moisture Sensors KZW-1A

Directly monitoring changes in moisture content in concrete is a rational and very effective method for quality control of concrete. 
Concrete Moisture Sensor can estimate the free water content (evaporable water at 105°C) of concrete from fresh concrete to hardened concrete by electrically and nondestructively monitoring changes in moisture content inside the concrete continuously from immediately after placement. 
This can be applied to determine the state of curing, the timing of formwork removal, and the timing of surface finishing. 
It can also be used for versatile purposes in fields such as research on hydration of concrete, which is closely related to the water content in concrete, durability, and maintenance management. 

Protection ratings: IP67 equivalent

Concrete Moisture Sensors KZW-1A
