These high-purity regulators designed for analytical, non-corrosive gas applications incorporate a Gas Watcher^TM Bluetooth Pressure Gauge that displays the source gas pressure on a digital readout and also remotely via a Bluetooth connection to a web based portal. A Receiver/Router and an Annual Monitoring/Reporting Service (first year included with Receiver/Router) is required to view the source gas pressure remotely on a computer, tablet or smart phone and has the ability to have pressure status alerts sent either by text and/or email.

Applications

• Supply of carrier gas/detector support gas for a variety of gas chromatography applications.
• Supply of calibration standards to on-line process analyzers, emission monitoring systems, etc.
• High purity applications with non-corrosive gases requiring a constant delivery pressure.

Design Features

• High-purity nickel plated brass barstock body
• High-purity 316 stainless steel diaphragm
• Metal to metal seals minimize diffusion of contaminants
• 2-1/2 delivery pressure gauge
• Equipped with outlet diaphragm valve
• Bonnet ported and threaded to pipe gases away from work area
• 1/4” compression tube outlet connection
• 10 micron metal filter protects seat from contamination
• Panel mountable, front bonnet and back bonnet threaded
• Optional interstage relief valve available
• Bonnet vent holes size: 1/8” FNPT

• Gas Watcher - Bluetooth Pressure Gauge
The Gas Watcher^TM Bluetooth Pressure Gauge displays the source gas pressure on a digital readout and also remotely via a Bluetooth connection to a web based portal. The operation and control settings for the Gas Watcher^TM are conveniently accessed through a set of two push buttons located on the face of the Gas Watcher^TM .

A Receiver/Router and an Annual Monitoring/Reporting Service (first year included with Receiver/Router) is required to view the source gas pressure remotely on a computer, tablet or smart phone and has the ability to have pressure status alerts sent either by text and/or email.
