The water pressure can be visually observed by the indentation of the membrane.
The change in water pressure is measured by the expansion of a thin rubber sheet attached to both sides of a transparent cylinder.
When the cylinder is placed in water, the rubber sheet bulges inward due to water pressure. By reading the size of this bulge on the scale, the strength of the water pressure can be determined. Water pressure detector: Made of acrylic resin, cylinder, φ56×D50mm, with mm scale
Support and air vent: Acrylic resin, φ10×D300mm, with mm scale
Product code: 125-210
