High and Low Velocity Leakage Testers

THE FAST WAY TO TEST FOR AIR LEAKAGE

These two units provide a comprehensive choice of equipment to test and quantify air leakage. Virtually anywhere low pressurisation is necessary, laboratory clean rooms, test cells or sealed enclosures, Airflow Leakage Testers provide a fast accurate measurement solution. The method of measuring the air flow rate is a primary standard using conical inlets directly related to BS848 Part 1. Electronic speed control (HVLT) and manual damper control (LVLT) is provided to adjust the flow rate/pressure delivered by the unit. Both units are portable in the average estate car and will allow periods of testing even in arduous site conditions. The new, state of the art, LM1 Electronic Leakage Manager offers instant measurement, display and control of system performance.
