OMS DIN Flow Meter

Want to check your mix, but don’t want to drag out your regulator just so you can? Just screw this into your Din valve and turn on the tank. No adjustments to make just read the analyzer.

What? Tanks aren’t DIN you say? Well now, we have an inexpensive adapter that will let it work on Yoke valves.

OMS BC Flow Meter

Plug this flow meter into your LPI hose, adjust flow to desired level and read the analyzer.

Dive Rite BC Flow Meter

Plug this flow meter into your LPI hose, no adjustment necessary, just read the analyzer.

Bc Adapters

So you want to use that OMS BC flow meter that came with your new analyzer but now you realize that your Inflator / Octo fitting isn’t going to fit on the flow meter! Well you could go thru the hassle and switch out hoses every time you want to check your mix OR you could get one of these little gizmos. Designed to adapt from an Inflator / Octo fitting to a standard Bc fitting all you do is hook it to the flow meter and leave it attached. Now just plug the Reg’s hose into the adapter and wala your reading the O2 %.

O2 Sensors

Replacement sensor for OMS Analyzer. We keep these on hand, not because they go bad often, but because at our super low price, we have sold so many of the OMS analyzers over the years we’re bound to need one from time to time. Hey, we have three on our wall, running 10 hrs a day and we still get over a year out of the sensors!

Other sensors are available. Call for pricing.

LP tubing

Use this tubing to extend the reach of your analyzer. Now you can leave it in it’s protective box and read O2% from as far away as you want. Heck, we have enough tubing on our shop analyzer to read tanks in the other room! Makes things easier when a lot of people need fills.

Sensor Not included

Oxygen sensors are designed to work best in very low constant flowing gas at steady temperatures. The ideal condition is therefore a still gas at 1Bar. Flowing gases above 2 litres per minute can cause back pressures and give elevated readings. The sensor will still have a fast 7 second response with flow rates down to 100 millitres per minute. A very gentle hiss or light pressure on the finger.

When measuring from a Scuba cylinder the gas released is very cold and if left flowing can cool the sensor membrane. This can cause the output to drift. The ideal solution has proved to be a small restricter (as in the Vandagraph DIN Kit) where the gas is sampled and then measured at 1Bar (1 atmosphere). The limitation of this method is that the assembly of the system takes time.

Hey, one of the worst things you can do to a piece of electronic equipment is to get it full of salt water. If you check your mix on the boat, you’re bound to get your analyzer wet if you don’t take some precautions! Yeah you can use a ziplock bag, but Murphy’s going to put a hole in it , fill the bag with water, and then drop your buddies weight belt on it for good measure, just to prove who is boss. NESS stocks a full line of ridged dry boxes to help protect the investment you made in a good analyzer.

This is a higher end version of the old flow meters.  The new ones use an actual first stage with a flow restrictor on it.  This way you can use the regulator for other options.
