Click-It™ Flowmeter

Allied’s new Click-It flowmeters are designed for use with hospital and EMS oxygen and air delivery systems where a precisely metered supply of gas is required. Click-It flowmeters offer a wide range of highly accurate flow rates regardless of orientation or visibility.

Unlike traditional Thorpe tube flowmeters, Click-It flowmeters allow the user to simply dial in the desired flow rate. The precision-machined knob clicks securely into place with each selected liter per minute flow setting while allowing for easy adjustment even with gloved hands. Laser-etched flow indications are clearly marked, making them easy to read even in low light situations.

Key Features
  • Positive-click dial with 11 flow selections
  • All-brass flow cartridge and metal adjustment knob for extended product life
  • Color-coded anodized aluminum housing for maximum durability
