Got this to help our eldest learn about pressure as he's fascinated by all things mechanical and loves tools too. Love the fact that this has a little carrying case so he can keep it nicely. They even provided him with a little screwdriver to change the batteries. Yes, it's a professional tool and has functions far beyond either of our capabilities, but he's been using it like a detective uses a magnifying glass. He's been using it with balloons, under doors in different rooms of the house, the tyres in his bike... it's got him looking everywhere for places where we can detect invisible forces of air pressure at work. Simple to use and comes with everything you need.

Das kompakte Messgerät im Taschenrechnerformat kommt mit 9V Batterie, Etui, 2 Messchläuchen und Schlauchtülle zum Einschrauben in ein Messrohr. Die beiden Anleitungen sind in Englisch und Chinesisch.Eine erste Messung erbrachte ein plausibles Ergebnis, sodass die Messgenauigkeit von 0,3% vermutlich zutrifft. Wichtig ist, dass man das Gerät vor dem Messen nullt indem man die HOLD Taste gedrückt hält.Der Messbereich ist mit einer 0,3%igen Ungenauigkeit zwischen - 0,206 und + 0,206 bar, und damit leider nicht besonders groß. . Der Preis scheint im Vergleich mit anderen Anbietern dennoch angemessen.Ich kann daher nichts Schlechtes berichten und vergebe 5 Sterne.
