Designed for rigorous industrial and quality control environments, the CETATEST 815 supports diverse pressure ranges (from negative to high positive), displays results in many units (Pa, ml/min, l/min, etc.), and offers programmable phases such as prefilling, stabilizing, measuring, and venting. Password protection and program memory ensure consistent repeatability.

CETATEST 815 Flow Tester

With support for gauge and differential sensors, versatile valve types, and many optional interfaces (RS-232, Profibus, Ethernet, etc.), the 815 adapts to many test setups. It comes calibrated (DAkkS), includes automatic checks (Still-Alive etc.), and offers reliability and precision through automatic test cycle oversight.

Features

Differential & Gauge Pressure Measurement

Simultaneous use of differential pressure sensors plus gauge pressure allows accurate leak detection across varying parts.

Multiple Test Modes & Phases

Supports modes like pressure decay, pressure rise, sealed component, dynamic pressure; phases include prefilling, stabilizing, measuring, venting.

Wide Pressure Ranges

Ranges from negative gauge (e.g. -1 bar) through small positive mbar ranges up to tens of bar, configurable depending on test requirements.

User Programmability & Security

64 user-programmable test programs with alphanumeric naming, password-protected levels, ability to save/import configurations.

Interfaces & Data Handling

Standard digital I/O and RS-232; optional Ethernet, Profibus, etc.; supports test curves, result statistics, memory export; includes software (CETA Soft).
