Page 14: Ph Calibration Related Information
For tough contaminants, soak the electrode in Apera cleaning solution (AI1166) for 30 minutes. Then use a soft brush to remove the contaminants. Afterwards, soak the electrode in 3M KCL solution (SKU: AI1107) for at least 1 hour. Rinse it off, then re-calibrate it before using again. The connector of the electrode should be kept clean and dry. - Page 15 Chart -3 Three-point calibration mode USA standard NIST standard CH standard Applicable range One-point Accuracy pH 7.00 pH 6.86 pH 6.86 calibration ≤± 0.1pH pH 7.00 and pH 6.86 and pH 6.86 and < pH 7.00 pH 4.00/1.68 pH 4.01/1.68 pH 4.00/1.68 Two-point calibration...

7.6.2 Relationship among TDS, salinity and conductivity The conversion coefficient between TDS and conductivity is 0.40~1.00 which can be adjusted in parameter setting clause 2.6. Factory default setting is 0.71. The conversion coefficient between salinity and conductivity is 0.5. So the meter only needs to be calibrated in conductivity mode, then switch to TDS and salinity mode. -
