Review on Testo 0560 1510 Digital Differential Pressure Gauge by Ryan Bennett

So it's about vacuum and gauge pressure and you have the option to choose different measurement options and all you have to do is use your mobile phone to get all the information very happy with the purchase. I work in HVAC so use it mostly for gas valves and pressure switches as well as ductwork and also static pressure. I am very happy with this innovation. I will buy more similar products from testo, overall very happy with the purchase.
