However, compliance with the EMC requirements is not possible without the use of proper cables and connector/gland assemblies. Bronkhorst recommends the use of their standard cables. These cables have the right connectors and if loose ends are used, these are marked to help prevent wrong connection. When using other cables, cable wire diameters should be sufficient to carry the supply current, and voltage loss must be kept as low as possible. -

2.10 Calibration EL-FLOW® Classic instruments are Air or N calibrated. Bronkhorst High-Tech B.V. certifies that all instruments meet the rated accuracy. They have been calibrated using measurement standards traceable to the standards of the Dutch Metrology Institute (VSL). The calibration is converted to the customer’s gas and conditions using a detailed conversion model. This conversion adds a level of calibration uncertainty. -
