the product introduction:
The rock wool plate thickness gauge is a professional testing instrument suitable for the measurement of the thickness and thickness of the plate made of mineral wool.Designed and manufactured according to GB/T5480—2008“Test methods for mineral wool and its products”.The utility model has the advantages of simple structure,convenient operation and large measuring range.
★Pressure on the platen:98Pa.
★Dial indicator range:0~10mm.
★Steel ruler measurement range:0-150mm.
Third,the method of use:
First measure the general thickness of the test sample with a steel ruler.For example,the test sample is about 56 mm thick.Use a steel ruler to measure the distance between the bottom plate of the gage and the platen to 50 mm.This value is the initial distance and then The moving beam of the gage is tightened,gently lift the platen of the gage,place the test sample between the bottom plate and the platen,gently lower the platen to make contact with the sample,and wait for the dial gauge reading The reading after stabilization is accurate to 0.1mm.If the reading is 6.1mm,the true thickness of the sample is the initial distance of 50mm and the measured thickness is 6.1mm=56.1mm.
Note:When using the steel ruler and thickness gauge to determine the initial thickness of the test sample,take the integer value closest to the sample.The measured value should not exceed 10mm.For example,the sample to be tested is about 20~30mm,the initial distance is set to 20mm,and the initial distance is 50mm when it is 50~60mm.For the same reason,the initial distance is up to 150mm.
Fourth,the operation steps:
★smoothly lift the waterproof coil gauge to measure the pressure plate,place a prepared sample to be placed between the measuring platen and the support,and gently lower the measuring plate to make contact with the sample.After the thickness gauge pointer is stable,record the reading of the dial gauge at this time,and then calculate the actual thickness of the sample.
★Repeat step 5 to measure the thickness of the remaining three samples and calculate the arithmetic mean of the thickness of the four samples as the thickness of the sample.For thickness measurements that require a sample of the overlay,the overlay should be placed down.However,if the metal mesh is veneered,the metal mesh should be removed before measurement.
First adjust the waterproof membrane thickness gauge to measure the bottom plane of the pressure plate parallel to the upper plane of the support.
★Prepare a sample to be tested.
According to the thickness of the sample to be tested,the corresponding reference block is selected and used as the measurement reference(Note:the reference block can be arbitrarily combined according to the height of the sample to be tested).
★Place the assembled reference block on the support,loosen the column locking handle,adjust the bracket up and down,press the measuring plate at the lower end of the dial gauge on the reference block,and make the dial indicator 0.2mm pre-Tightly,then lock the column lock handle and record the dial gauge reading,lift the measurement platen,and remove the reference block.
