Liquid Manometers & Meters

A range of general purpose laboratory manometers using liquid displace-ment to measure differential pressure.

A range of manometers measuring differential water pressures up to ap-proximately 12.6m H2O. Scales are graduated in 1mm divisions.

H12-1: 1 metre scale differential open water manometer

H12-2: 1 metre scale differential pressurised water manometer (the air space above the tubes can be pressurised with the pump sup-plied)

H12-5: 500mm scale differential kerosene over water manometer – Range 0.213m H2O

Portable Pressure Meter

A versatile, hand held, battery operated portable pressure meter capable of measuring pressures of water or air from 0 – 2000 mBar (0 – 1500mmHg).

This unit is particularly suitable for use in applications where Mercury manometers have traditionally been used. The use of Mercury is not desirable in a laboratory environment due to its hazardous nature.

A battery operated portable pressure meter suitable for measuring gauge (single input) or differential (dual inputs) pressures of air or water.

Measurement capacity is up to 2 Bar differentially and the unit is capable of withstanding 6 Bar on either port without damage.

Housed in a robust, waterproof case and designed to be hand held. Supplied with connections to suit 6mm flexible hose.

An adjustable zero value eliminates offset and an averaging filter function provides steady readings in situations where the pressure is fluctuating. Readings can be displayed in alternative pressure units.

A calibration certificate referred to National Physical Laboratory (NPL: 5 point calibration) or United Kingdom Accreditation Service (UKAS: 10 point calibration) standards can be supplied if ordered with the meter.
