You may have to get EC pen or TDS pen as well

The Apera pH60 is an excellent pH pen, I’ve been using them for many years, but it’s not a combo unit. You need a separate device for reading EC/TDS. The comparable one from Apera is the EC60, also an excellent pen.

Wish the apera wasn’t so top heavy. Can’t sit in a shot glass without tipping over

PC 60. This is the multipurpose one I have and does both but it’s over $100 but a very good tool to have

@Bluntsmoke, they stand up perfectly in the little test caps that they come with for calibration purposes. I mix several 5 gallon jugs a night, and they fit perfectly in the neck of the jugs and just reach down into the solution.

@Bluntsmoke they register so fast I just swish it in my 5 gallon bucket. Or I have 1 liter pitchers that I put the solution in to take a reading.
@Lnnicholas you don’t need to go crazy with EC/TDS meters. All they have to do is measure electric current. I think the basic meters do just fine. I used a Honeforest TDS meter for quite a while. Good value for $20
