• Conductivity Value (µS): 1413
• +/- 1% accuracy at 25°C
• TDS Values: 744.7 ppm KCI, 702.1 ppm NaCI, 1000 ppm 442
• Oakton conductivity/TDS calibration solutions are cross checked by using different test methods, premixed and ready to use

The Oakton Conductivity/TDS calibration solutions are cross-checked using different test methods, premixed, and ready to use. Each bottle is labeled with the name and CAS number for all ingredients to conform with “Right-to-Know” requirements and includes an MSDS. Solutions come in one-pint bottles.

TDS standards in ppm KCl, NaCl, and 442 conversions are also printed on the bottle for ease of use. Temperature corrections are printed on the bottle, with the certified values listed in the tables, accurate to within ±1%, and are referenced to 25°C.
