S8830 Digital Differential Pressure Manometer

Fast, Precise Pressure Testing for HVAC Field Work

Measure static and differential pressure quickly with the compact S8830 digital manometer. Built for HVAC technicians, gas-line installers, and system-balancing professionals, its dual input ports make it easy to troubleshoot ductwork airflow, check appliance pressure, and evaluate filter pressure drops.

A backlit LCD and dedicated function controls keep readings clear and useful in mechanical rooms, attics, and other demanding service environments.

Key Features

Dual-Port Differential Measurement: Uses P1 and P2 hose ports to measure individual pressure points or calculate the difference between them.

12 Selectable Pressure Units: Switch between inH2O, psi, mbar, kPa, mmHg, bar, Pa, ftH2O, cmH2O, inHg, oz/in², and kg/cm².

DIF Function: Toggles differential pressure mode for quick comparative analysis.

MAX / MIN / REC: Captures peak, low, and recorded pressure values.

HOLD / Backlight: Freezes the current reading and illuminates the display in low-light work areas.

UNITS / REL: Changes measurement units and zeros the meter for relative pressure readings.

Auto Power-Off: Helps preserve battery life during field service.

Ergonomic Design: Molded side grips provide a secure, comfortable hold on the jobsite.
