I bought the cheapo $20 amazon ph and tds meters and found they were often giving inconsistent readings. Then I bought the bluelab combo kit with the ph and tds meter. The ph meter still works great but I didn't want to spend another $150 on a tds meter to have it only last a year and a half. This one only cost a little more than the combo kit.I want one...I'm tired of using cheapos....I always use 2 of them for a double reading to make sure I'm on....and I need to splurge and buy a better monitor unit for the aero tank.
OK, I just looked at the price, and I don't want one near so much any more
I'm going to keep it in the case with the lid on. You can buy replacement tips for $70Mine is similar to that..... be careful with the tip. I’ve broke two so for. It works great except when the tip is broke.....so I am very careful when putting the tip in now
It came with a little bottle of that stuff.Spare that tip with the right lube
