Liquid column manometers are reliable and inexpensive traditional pressure gauges.
The manometers are good for measuring and indicating small overpressure, underpressure and differential pressure of air and non-aggressive gases in low pressure ranges.
U-Tube manometers are ideal for monitoring of air filters for contamination and monitoring airflow and air velocity in all HVAC applications, air-conditioning and ventilation.
The package includes:
- 20 ml of red Manometer fluid with density of 0.78
- 2 m hose ø 4/7 mm
