Review on 🚗 Advanced Car Smoke Machine: EVAP Smoke Leak Tester and Fuel Leakage Diagnostic Tester with FlowMeter - Perfect for 12V Vehicles and Boats! by Devin Henry

I sent this email to the company over a week ago and have not received a reply. (I just bought an SDT 206 and it has two gauges, actually 3 (one is barometric pressure). One has an alarm above the gauge and my manual doesn't say anything about it. Why does the website glass say LOW 50 75 Max. What about the handle? I'm pretty sure the other sight glass controls the air pressure and the other sight glass controls the smoke? The tool with the red handle is for removing the purge valve? Sorry but there is no proper manual, the manual for that comes with this unit came no sight glass of the alarm, and what happens when the alarm goes off, what can cause it to go off?. Thanks) I still haven't heard from you, but I have a new question, I'd like to close one here Fuse on and I'm curious to see how many amperes are required for this. I think I'll come here to ask questions
