Question: Can i do a hydrostatic test with this gauge using H2O, reading the water pressure
Document: Overall I highly recommend this over an analog gauge. For twice the price of an analog gauge you get far more functionality.I'd like to see Pyle add a configurable power down timer to allow for 2 hour recording to cover a typical pressurized gas system test.
I have been using this instrument on my work bench for several months and it works well. There is a "warm up" shift of +2 to 3 counts (right hand digit) for the first minute or two, then the reading is very stable over tens of minutes.
Its easy to use. Very accurate readings and priced right. I use it for checking gas pressure on Water heaters, and did not want a lot of extras I didn't need.
My service department calibrates all kinds of hospital equipment. We had been carrying around a large box filled with many different gauges some costing over $100 each. This device is small, easy to read, and allows us to check every pressure or vacuumn measurement needed in our serive calls', except some high PSI  procedures for which we carry an external gauge.HIGHLY RECOMMENDED.
Most gas system pressure tests require a minimum of a two hour test, so it would be nice to have it record min/max/avg for that period. Instead, whether you are recording or not, the unit powers down by itself after a shorter period of time (I don't exactly but it was more than 10 minutes and less than 1 hour).It does include a small carrying case to protect the instrument. Unfortunately the case has no space for the vinyl tubes that come with it.
Works great i used for tuning boilers to hot water heaters!! Works greatWorks greatWorks greatWorks greatWorks greatWorks greatWorks greatWorks great
If you have a wood furnace like me I would highly recommend this. I use it for testing my chimney exhaust water column when installing my chimney pipe to make sure that I am getting a good burn and the gases are flowing at the right rate.
I wanted to have a method to measure pressure differential through an air filter and this will serve that  purpose well. The price was right too.
Have not got a chance to use yet because hoses are smaller than pressure switch ports. Have to go buy additional connector and bigger hoses.
Purchased Manometer to monitor crank case pressure on marine diesel engines. Have not actually used unit but seems intuitive and easy to operate.
Answer: no
