Yfyiqi Sand Mould Surface Durometer Sclerometer Wet Sand Mould Surface Hardness Tester Meter Gauge Sand Mould Hardness Measurement B Type with Maximum Load 980G Compression Stroke 2.50mm

YFYIQI Sand Mould Surface Durometer Sclerometer Wet Sand Mould Surface Hardness Tester Meter Gauge Sand Mould Hardness Measurement B Type with Maximum Load 980G Compression Stroke 2.50mm Usage method: ★Adjust the 0 bit, when the pointer is not in the 0 bit, turn the adjustment ring, so that the pointer to 0. ★When used, the hardness is pressed in the sand on the test plane (axis hardness of the surface to be perpendicular to the plane of the sand), sand hardness meter gauge plane and the close contact, the pointer is stopped at a certain value, press the locking pin to lock, reading test a fixed value, and then releasing the locking pin so that the pointer reply 0. ★The determination was made at 3~5 times per assay, and then the average number was calculated, as well as the hardness of the part. Technical parameter: ★Model: B type ★Compression stroke: 2.50mm ★Maximum load: 980G ★Load under pressure: 50g ★Head shape and size: Ball R12.70 ★Accuracy: When the pointer is at any value, the relative force of the pressure head is equal to + 5% When the pointer goes back to the 0 bit, the tolerance is 1 degrees ★Outline size:90 x 55 x 28mm Load under pressure: 50g Head shape and size: Ball R12.70 Adjust the 0 bit, when the pointer is not in the 0 bit, turn the adjustment ring, so that the pointer to 0.
