Calgaz, the world’s leading manufacturer of calibration gases and equipment, is proud to offer the most comprehensive range of specialist regulators globally for non-refillable and portable gas cylinders.
The 1700 series regulators are designed to provide an adjustable flow rate and are typically used with low ppm reactive gases and other high-purity gas mixtures. The 1767 and 1781 models are preset at the production facility to a user-specified flow rate between 0.1 LPM and 6.0 LPM.
The 1768 and 1782 models can be adjusted on-site by the user. The units are supplied with an easily adjustable outlet flow controller. The flow controller permits adjustment of flows to any point between 0.3 – 2.0 LPM.
The 1700 series regulators are designed for use with the Calgaz 2AL, 8AL, 10AL, and 6D cylinders.
All regulators carry a 24-month warranty, and we recommend replacing them after two years of service.
