2 ph testers and 2 ppm testers. I have the solution for the ppm/tds testers but I lost the manuals for everything and I’m in a tough spot. Just need one pair of working testers. Can anyone point me towards the manual or give me instructions? I’m trying to get back into hydro and I’d really appreciate your help. Thank you!

U can take the names from the pens and search via google. The high end companys have video Tutorials on YT
Or just hold the cal button and look what the display wants ^^
