Concrete carbonation test chamber is a special equipment in the carbonation test. This machine uses imported carbon dioxide sensor.The sensor adopts infrared detection principle and combined with the national advanced digital instrument, which has the high precision and long life characters; temperature and humidity sensor is composed of national highly advanced induction module and more channels intelligent instruments. This product has high control accuracy, simple operation, inside temperature, humidity, concentration and timing printing directly record digital features.

The FBG Anchor (Bolt) Dynamometer is made of constant elastic, high-strength, and corrosion-resistant materials. Two FBG strain gauges are installed on the annular elastic base to accurately measure the total amount of various load from bearing cables, anchors and bolts. The product has a built-in temperature compensation FBG, and the temperature compensation can realize temperature measurement at the same time. It is generally used in coal mines, tunnels, foundation pits and other civil environments that require protection and support. As a bolt force measuring gasket, it can be used for monitoring the fixing of wind turbine blades, real-time monitoring of the locking status of shield segments, and other environments for monitoring the fastening status of bolts.
