## Description

Product description More Recommendations pH and TDS Meter Combo Digital pH Meter Kit pH Meter TDS Meter

Review: Meter Accuracte down to One tenth - Although it may be a little delicate to calibrate upon first time using. Insure solution temperature is ~75 degrees F. Measure out 250 ml distilled water. Insert the meter into a cup pour into another cup until you reach the line on the meter. Turn meter on holding down the calibrate button for 5 seconds then release. Press Cal button one more time. I did not get a display showing "cal" like some of the YT videos. This generates confidence in the meter concerns. However, I had a lab tech at the university check the calibration in a buffer solution of 7.0 and the meter showed 6.97. First pH meter that works and provides accurate results.
Review: Simple to use and well made - Works as advertised. Comes with buffer packs to calibrate. Would 100 percent buy another when this ones life is up. Thanks yall! Vivosun is my go to grow store online. Always what i expect! Love yall!

Defective. Will not calibrate. I followed all the calibration instructions and the meter just keeps flashing "Err". This was a waste of money that's going straight in the trash.
