Unlike a typical dial gauge, the four columns are placed side by side for comparison and reading.
1. The calibration unit is cm Hg (range: 8-42 cm Hg).
2. Make sure the four-cylinder balance gauge is vertical.
3. The instrument does not need to be zeroed or calibrated. All parts are aligned when assembled.
4. Dirt or oil stains will get into the pressure gauge. The stainless steel column is difficult to move and can be cleaned.
5. After use, first remove the black rubber tube from the four-cylinder balance gauge, then remove it from the inlet and hang the rubber tube to drain the fuel.
Principle:
The stainless steel column is used to replace highly toxic mercury in balance gauges. The stainless steel column is sucked in by the negative pressure of the engine and floats in the transparent pipe to indicate the balance state.
More accurate than any dial or clock pressure gauge we have tested.
Better resolution than a typical dial indicator.
Unlike a typical dial indicator, the four columns are next to each other for comparison and reading.
