TCGB-26 Geomembrane Rough Thickness Gauge is designed ａnd manufactured according to CJ/T234 standard. It is mainly suitable for the thickness measurement of the rough geomembrane ａnd its related products. It has the advantages of convenient use ａnd accurate measurement accuracy.

1, measuring range: 0-12mm

2, measuring accuracy: 0.01mm

3. Coaxial pressure: 0.56N+0.05

4. Overall dimension: 140x120x200mm

5. Weight: 1.5kg

1. Test the sample with good state adjustment under the specified standard laboratory environment conditions.

2 The gauge is zeroed or an initial non-zero reading is recorded by applying a specific force to the pressure point at the base point (no sample is placed).

3. Raise the pressure point ａnd ｉnsert the sample. When the pressure point is slowly in contact with the sample, the position of the sample is adjusted so that the measuring point is at the "low point" or "low point" in the depression between the protrusions of the rough surface to obtain a local minimum thickness reading. Repeat the above steps to obtain a total of 3 measured readings for each sample. Take the minimum of the three readings as the thickness of the sample ａnd the results are required to be accurate to 0.025mm.

4. When measuring, the measuring device shall stand for 5s under the condition of full static load pressure, ａnd then record the thickness value according to the accuracy of the measuring device.

5. Calculate the average thickness of the sample with the results of all samples, ａnd record it accurately to 0.025mm.

6, measuring specimen thickness below 10mm does not need to add the standard block.
