Dual-Port Differential Pressure Test
Simultaneously measure IN1, IN2, and differential pressure for faster comparison during pressure and vacuum diagnosis.
Wide Measurement Range
Supports -100~300kPa / -1000~3000hPa pressure range for both low-pressure and higher-pressure diagnostic environments.
High Accuracy Sensor
±0.25%FS accuracy with temperature compensation helps provide more stable results, even in cold regions.
10 Pressure Units
Switch between kPa, hPa, Torr, mbar, inHg, mmHg, inH₂O, mmH₂O, psi, and kg/cm². Pa display is no longer supported.
Data Locking And Storage
Lock current readings, perform zeroing, store records, and review up to 29 data sets for on-site checks and later recording.
Magnetic Back Plate
The magnetic backing easily attaches to metallic vehicle components, supporting hands-free measurement during workshop work.
Backlight And Flashlight
Backlit screen, illuminated buttons, and built-in flashlight help users read and operate the meter in dark environments.
Drop-Resistant Casing
Lead elements are added to the casing to improve impact resistance and help protect the machine if accidentally dropped.
