The Airflow Type 504/500 Inclined Manometer is a highly sensitive instrument with a scale length of 250 mm, covering the range of 0-500 Pascals. The gauge is suitable for wall or panel mounting with the fixing kit supplied, or it can be fitted with an optional bench stand incorporating leveling adjustment. The steel casing carries an extruded support for the anodised aluminium scale and precision bore, sight glass. A spirit level is provided for accurate leveling. The combination of long scale length gives precise measurement of low pressures.
