Description

This DSZH gauge pair consists of a blue-bezel low-side gauge and a red-bezel high-side gauge, each with a brass NPT threaded stem for mounting on a manifold. The dials are printed with dual PSI and kg/cm² scales alongside reference markings for common refrigerants including R-22, R-12, R134a, and R-502. They are used to read suction and discharge pressures during refrigerant charging, recovery, and system diagnostics.
