can you just check the psi of one tank, so you can find a tank on a dive boat that has more air than others????
GARY M Yes, as long as you have the yolk valve on the tank-to-be-filled closed and both equializer bleed-offs closed, the gauge will read the pressure in the hose which is the tank you are filling from. If the pressure is less than that of the tank-to-be-filled, just close the valve on the fill-from-tank and open one of the bleed-off hose valves to depressure the equalizer hose, swithch to another fill-from-tank, be sure to close the bleed-off valve before opening the yolk valve on the fill-from-tank..........read press. on gauge, if greater than the to fill tank, then open the yolk valve on that tank....filling slow is probably safer than a rapid gush of air. My hose has worked great to fill a pony tank that I travel with on dive trips; the metal on the hose end crimps has rusted, minor flaw.
EARL S yes you can but you must have the the one end hooked up to a tank with the valve off.
then you can hook the other end to the tanks you want to test.
BRIAN H No, not unless you connect two tanks together. Now, it's possible to only open one valve at a time to check PSI, but the hose is open on each end.
BTW, I bought one and it's a very well made whip.
JAMES D To could by connection one end to a tank with the air turned off and then to the other end to the tank whose pressure you want to check. Turn on the tank you want to test the pressure. Once the reading is taken, turn the tank off and release the pressure. Proceed to the next tank you want to check and repeat.
WILLIAM B Yes and No.
You cannot hook it to one tank and read the pressure as the other yoke would be open.
However if you connect to 2 tanks and only open one tank valve the second tank acts as a plug and the gauge will read accurately. using this process you can check two tanks.
Connect to both, open one tank valve, read, close tank valve on tank one and open tank two. Optionally you could bleed off pressure before opening the second tank but the hose volume is so small it will not really affect the reading.
JOHN K The answer to your question is "Yes". However, both ends will need to be attached to tanks. Just open one tank valve at a time. The gauge indicates pressure in the line. It may be possible to insert some sort of block-off on one side of the equalizer, but time wise it easier to attach 2 tanks, and leave the tank with the lowest pressure attached.
STEPHEN W It's been awhile since I've used it but you would have to have the other end connected to a tank with the valve closed to keep the air from the tank your checking from bleeding out. You can hook it up between two tanks you want to check but only open one tank at a time to check the psi of each one seperatly.
ERIC B The tank equalizer has to be connect to two tanks since there are no isolation valves on the hose. So connect the hose to two tanks. Only open the tank valve of the one you need to check the pressure. Then close that tank and open the other tank to check its psi. If you only have one tank you can not use this device.
MICHAEL P Yes if the other end is hooked up to another tank and that valve is off.
BARRY S To do this you'd have to hook two tanks up and just open the one with the pressure gauge closest to the end. The other option is to install a shut-off valve on either side. Hope that helps.
STEVEN L No, you would have to purchase a valve for the other end that you could put inline, otherwise the air would flow out the end that wasn't hooked to a tank.
JENNIFER R You can use it as a tank checker, but you still have to hook it up to two tanks, close off one end & then check the air on the other tank.
ROBERT E both ends must be connected to tanks,then you can either one for pressure
EDWIN S You'd be better off checking with your personal regulator. To check a tanks pressure using this device you need to have it connected to two tanks!
NUNZIO C Funny you ask, because that was partly the reason I had bought it! But no; if you connect it to a sole tank then it just bleeds air out.
TODD B You can not easily check the pressure on a single tank. The way the whip ships, it is just two yolks with bleed valves and a gauge, there is no way to stop the air from exiting the other end. You can use it to check pressure but you need to connect the whip to two tanks. I can't help but think a dive operator would frown on this for a number or reasons. We use these whips to transfer air from tank to tank. I.E. if you dive your lp108 down to 1000psi then whip if from one at 3000psi to give you 2 tanks at 2000psi which roughly translates to the volume of 3 Aluminu 80's but only carrying 2 tanks.
JERRY K Yes, you can do it. The procedure would be to connect an equalizer to both tanks and open the valve of the tank you want to check the pressure in. Then do the oposite by closing both valves, venting air and openning the other valve.
TOM B This is not designed to check the psi on a single scuba cylinder. Once connected between two scuba cylinders, the scuba cylinders valves are opened and the air pressure is equalized between them. The pressure gauge will display what ever the pressure is at that time. To check the pressure on a single scuba cylinder you need to get a Tank Pressure Gauge.
MARCUS A No, it is not possible with this setup as both ends of the hose must be attached to tanks. Pressurizing just one end of the hose will simply drain the tank.
There are tank gauges available for this purpose available at LeisurePro, or you can make one for yourself with an old primary reg stage with all the ports plugged except for one with an old pressure gauge on it. I use this at home and it works quite well.
CONRAD P Yes you can, I have two tanks and I sometimes use them for pressure tools in the garage. This adaptor lets me measure the pressure in each tank (it records the pressure in the crossover pipe), so I can figure out when each tank is getting too low to use.
