This non-submersible industrial digital pressure gauge provides exceptional accuracy, reliability and repeatability. Pressure range of 5 to 5000 psi with the 1/4" NPT male fitting that is widely used in dive industry compressed gas handling and blending applications. Corrosion resistant compatibility with all gases commonly seen in the SCUBA industry: Air, Nitrox, Oxygen, Trimix, and Helium. The wetted surfaces and inlet fitting are oxygen compatible 316L stainless steel and Nitrox Ready.

Key Features:

  • Easy-to-read 4-digit LCD display w/backlight - Push-button controls
  • User selectable units of measure: PSI, BAR, or MPA (kg/cm2)
  • Range 5 to 5000 PSI with accuracy better than ±1% full scale (±3 @ 300 psi, ±30 at 3000 psi)
  • Auto zero and maximum peak pressure memory recall and reset
  • 2.5" Thermoplastic housing with 1/4-inch NPT fitting and rubber boot, NEMA 4X weatherproof
  • All wetted surfaces of the gauge are 316L stainless steel
  • Battery saver automatically shuts off the display after 3 minutes
  • Requires one standard 9V alkaline battery
  • Use oxygen service PTFE seal tape on threads, maximum torque is 150 in lbs +/- 1 in lb

This is NOT an SPG for use underwater with your SCUBA regulator; it is intended for gas handling and blending applications that commonly support recreational sport and technical diving. The industrial housing is rated NEMA 4x weatherproof and resists corrosion but is NOT rated as IP68 waterproof. Do NOT submerge and avoid storage open to marine or high moisture environments. Remove the 9V alkaline battery for long term storage.

Tek Tip Warning Image WARNING
According to our suppliers, this product is compatible with oxygen. Nonetheless, the 'clean state' of this equipment applies only prior to initial use. Thereafter, periodic inspection and cleaning are a necessity. You must meticulously follow the recommendations of the US Department of Transportation (DOT), Compressed Gas Association (CGA), and other federal/state/local agencies, plus your dive training agency for equipment maintenance, handling, storage, labeling, filling, transport and use of compressed gases. Oxygen-related fires and explosions can result in serious injury or death. Ultimately, you must make the final decision to assume all risks associated with the use of any compressed gases, including those in excess of 23.5% oxygen.

Using PTFE (aka Teflon) Thread Seal Tape with Oxygen, Nitrox and Trimix

Pure polytetrafluoroethylene (PTFE aka Teflon) thread seal tape may be used as appropriate for joining or sealing the threads of gas handling equipment in oxygen applications, provided it is lubricant-free and properly applied. The recommended grade is GSA A-A-58092 Type II Size 1, a US Federal commercial description for the quality of full density polytetrafluoroethylene thread seal tape. 'Type II' just means the tape is packaged on a plastic spool with a snap-on cover. A relatively uncommon 1/4-inch width (termed 'Size 1') is most appropriate for use with the smaller NPT fittings typically seen in SCUBA applications. The tape must be at least 99% pure PTFE, the remaining 1% to allow for the addition of an oxygen compatible color pigment. PTFE tape is available in a rainbow of colors, although green is commonly associated in the US with oyxgen there is no official standard for color and white is by far the most common color. The PTFE tape must be applied to clean threads with two full wraps to a maximum of three wraps (i.e. about two and half wraps), taking care to ensure it is not contaminated while being applied and loose strands are not exposed to high velocity gas streams.

However, PTFE tape is available in various other grades, some of which contain a large proportion of material other than PTFE. Avoid plumbing grades of 'pipe tape' that only meet the T27730A standard (with weak specifications for purity and density) and are often lubricated. The industry also sees a lot of generic product produced offshore that does not conform to the standards they claim to meet, substituting cheap or low quality materials. If any of these grades of tape come into contact with high pressure oxygen there is a chance that an ignition will occur with the risk of injury to the operator and damage to the equipment. While oxygen compatible materials are not readily combustible, nearly all materials can still serve as fuel in the kindling chain of an oxygen fire. The use of oxygen compatible materials does not eliminate the need to always follow best practices for oxygen handing, including avoiding contamination and opening valves slowly.
