About This Product
Through the clear back, students watch the curved tube straighten slightly under pressure and turn the pointer through the rack and pinion, which explains how most dial gauges work. The gauge can be connected to gas-law apparatus to log pressure, and the twin scales give practice converting between kg/cm² and psi.
