Cement hardness tester AL-150N meets with the requirement of JGJ/T23-2001 and is used to detect the concrete compressive strength within the scope of 20-60 Mpa, and the system power is 2.207J.it is medium analogue display.
This cement hardness tester execute GB9138-88 and JJG817-1993 national metro-logical verification code standards and under the supervise of China construction institute. Cement hardness tester is applied at detection the strength of general construction, Bridges, and various propose artifacts (plate, beam, column, bridge).
Feature:
1, Center guide adopts imported materials, high accuracy, resistance to wear and tear.
2, Shell is made of super hard aluminum, avoid on-site damage equipment, prolong service life.
3, Pointer block the external type spring coil structure, convenient for friction adjustment, and can guarantee pointer shaft and pointer slider friction force uniform, to ensure the accuracy of the instrument.
