You explained it perfectly thankyou so much
Glad it was helpful!
I like it! The explanation is clear.
So the true reading is only when it’s in the water for 5 seconds if it keeps dropping the longer you hold it in the water is the wrong reading ?
The meter will stabilize within a few points usually after about 5-10 seconds. The rate of stabilization really depends on how far the pH swing is when the meter is submerged. It takes longer for the meter to “hone-in” on the reading when the pH is either unusually high or unusually low. Hopefully that makes sense. If not, just give me a call: 610.657.8800
TDS is measured based on ppm500 or ppm700 scale?
This meter is for measuring on the 500 ppm scale – which is meant for salts and solids in water. The 700 ppm scale is specifically for measuring Potassium Chloride.
