🗣️You may want to know.
- The digital manifold pressure tester measures gauge pressure, with a range of -101 kPa to 6 MPa (-0.1 bar to 60 bar) and a limit of 10 MPa (100 bar). The standard hose’s max operating pressure is 600 PSI (about 4.13 MPa, 41.3 bar), with a limit of 3000 PSI (about 20.68 MPa, 206.8 bar).
- Please confirm the rated pressure of the tested equipment before testing. Do not use if it exceeds the instrument’s range. Also, for DY517A, if the packed…
hoses does not match the pressure requirement, you can use suitable replacements for testing. - Do not use and store the instrument in high temperature, high humidity, flammable, explosive and strong electromagnetic fields.
- Please do not change the instrument internal circuit, to avoid any damage of the instrument or danger occurring.
- Please wear qualified protective equipment to protect user during testing.
- Please use the instrument in a well-ventilated environment to prevent inhalation of toxic gases.

It's decent . You can recalibrate and zero out the pressure but you could have pressure in your lines still. Temperature sensors are good but would work better if the clamps had a copper insert for the sensor that covered the surface area of the hoses toy clamp to. I'm gonna make some new clamps with my 3d printer and add space for thermal conducting material in the clamp so the sensor gets a more accurate reading. But still it's decent for the cost.
These gauges work great they are pretty accurate and will recommend to others great value thank you
Give your freedom of thermostats and tapes around the pipes to check for super heat and sub cooling, it’s just great .recommend 100%
