Gypsum board thickness tester is a testing instrument for measuring the thickness of gypsum board. It can also be used to measure the thickness of other materials. However, it is necessary to replace the upper and lower probes according to the different requirements of the measured material and size (this instrument does not have accessories) ). Such as measuring the depth of the spiral groove on the drill (using a pointed probe); measuring the thickness of wood, plywood, composite board and other plates (using a spherical probe).
Main technical parameters of gypsum board thickness tester:
Measuring range: 0-30mm
Reading accuracy: 0.01mm
Handshake frame depth: 116mm
Net weight: 1.5kg
Structure and working principle of gypsum board thickness tester:
A dial indicator was pushed over the open end of the handshake. Tightened by screws: The original spherical measuring head of the dial indicator was replaced with a disc-shaped measuring head. When the upper end of the dial indicator is depressed during work, the measuring rod on the dial indicator can also be lowered at the same time. Spring return on the sub-meter. A dial indicator was pressed on the open end of the handshake frame and locked by screws. The original spherical measuring rod of the dial indicator was also lowered at the same time. After letting go, rely on the spring on the dial indicator to reset. A measuring head is pressed under the open end of the handshake frame. The lower measuring head is supported by the M3 pusher set screw and a M3 cylindrical head screw is tightened, so that the lower measuring head can be adjusted parallel to the upper measuring head.
Gypsum board thickness tester operation and adjustment Before use, check whether the size pointer on the dial indicator points to zero, so that you can screw in to adjust the upper and lower positions of the dial indicator, and then tighten, if the large pointer is not in the zero position, you can turn the 100 Adjust the case.
When the upper and lower measuring heads are in contact, the sides should be in full contact and should not be tilted. If it is tilted, loosen the M3 valve head head screw, then adjust the pusher set screw to make full contact, and then tighten the cylinder head screw. When measuring the thickness of the plate, you can insert half of it between the measuring heads at both ends, and then move the measuring rod up and down so that the two measuring heads are in close contact with the plate. At this time, the thickness of the measured plate can be read directly on the dial indicator. Refers to integers in millimeters and large pointers to decimals.
Gypsum board thickness tester maintenance
This instrument is a precision measuring tool. After use, wipe it with a soft cloth and store it properly. The instrument should not be disassembled in order to avoid damage.
