Check the listing for details. SCUBA Tank Pressure Checker (Yoke) - pneumatic/pneumo versions also. Condition: New. Listed at 69.48 USD. Yoke Tank Pressure Checkers Like the DIN pressure checker, these are surprisingly useful, saving having to dig around for a set of regs when you want to check tank pressures, and with less bits hanging off it. Like most yokes, they are rated to 232bar, and there are different options depending on your budget and how cool you like your gadgets. The pneumatic versions are pricey but very difficult to source and let you connect/disconnect in literally a snap - useful if you're checking a lot of tanks in the back of the shop before a big bunch of customers comes in. They are available separately for your tank filling hoses. All have rubber boots on the gauges (a different style on 40-409-1) to protect them.
