Product Description
Accurate water analysis begins with a good calibration, and these solutions give you known reference points to calibrate against. The range includes pH buffers from 1.68 to 12.45, conductivity standards from 84 µS/cm to 12.88 mS/cm, and solutions for electrode storage, refilling and zero-oxygen checks.
This listing is for OHAUS item number 30100427: pH 7.00 Buffer Solution, 250 mL. Buffers and conductivity standards are supplied in 250 mL bottles for routine calibration of pH and conductivity meters. Electrode care solutions include a 3M KCl protection solution for storage, KCl electrolyte saturated with AgCl for refilling, and zero-oxygen chemicals for setting the zero point on Starter dissolved oxygen meters. LIGHT LABS ships genuine OHAUS products and can help you match accessories and parts to your instrument.
