i have and do digitol and chemical testing. and digitol can through ya off. if ya purchase a cheep one over time it will not give good readings. i back up my test with the chem drops but haveing a good ballpark reading is what ya want.
between 6.0 and 7.0 it is ten times for every 0.1 so if a meters prob goes bad or out of calibration you can kill your plants. if ya have some $$$ get one that has changeable probs and calibration ability. but i do prefer the 3 drops in a vial and never had a problem . even my meters are right on acurate and calibratible[because of my former profession.] i have tested millions of gallons of water and adjusted millions of gallons. so it is easy for me.
