I'd steer clear of either of these. They are one stage up from toys....

Alright M_C

I have both them testers and when seeing your post did a google search on top ten ph ec meters and they came up top.
How come you don’t rate them mate?

Thanks in advance

The PH testers are China's cheapest - replacement battery's cost more than the meter. Calibration is a regular thing with these

(I only need to recalibrate mine every grow as the drift every three/four months is around 0.1)

The TDS meters are, again, chinas cheapest! A TDS meter is NOT an EC meter - as you have found, you need to convert the number it gives you - and, as for PPM, does it tell you which PPM scale it is using? If not, the PPM function is next to useless...

Buy cheap, buy twice...

I would imagine, if google has them in the top 10 then it is by manipulation as there are much better PH & EC meters out there to populate a top 10 list

If you want top quality then buy BluLab (I don't have bluelab)

Agree about buy cheep buy twice totally.

I’ll have to calibrate both as not used them in a year or so. Ha
Will take a look at the blulab stuf and others.
Someone said in me diary what make it was from there found the scale and working with that.
At the mo

the grows going ok

Thanks in advance

If you don't use them on a regular basis then it matters less but coco growers use these daily & most hydro guys use them at least weekly. Tools of the trade & all that

If you want to knock a nail in occasionally, you buy a cheap hammer... if you do it all the time, you buy a hammer that will last

Haha yes m_c.
Been using them every day so far and will be till harvest if I get there ha. Checked my tap water with them and seems ok.
Will get some buffer solution todo a calibration.
Them bluelab testers are a little out me price range at the mo.

Thanks in advance
