LC-615A Air Content Tester
Product summary
This instrument (as shown in the figure) uses the air pressure method to determine the air content of concrete. There are two ways to measure the gas content by injecting water, and the operation is simple and accurate. The gas content value can be directly read from the dial. The black scale is read for water injection type measurement, and the red scale is read for non water injection type measurement.
Product feature
1. The machine is made of special lightweight aluminum alloy, with precision machining on the inner wall. It is lightweight and corrosion-resistant, with a capacity of 7000ml.
2. Dial, air chamber, exhaust (water) port, fine adjustment valve, pressure balance valve, hand pump, water injection valve, clamp.
3. Accessories include scraper, tamper, water injector, copper tube, U-shaped tube, and measuring cylinder for testing.
4.Weight: Approximately 10Kg
