  • Solutions made specifically for Oakton® meters and testers.
Oakton pH 4.01, pH 7.00 & 1413 TDS Solution

    For optimal performance, re-calibrate your meters periodically or if testing TDS or
    conductivity levels in wide or different ranges.

  • NaCl calibration solution.
  • Comes in lightweight HDPE plastic bottles.
  • Sealed with a coated foam liner.
HM Digital TDS Calibration Solution

    TDS solution are produced with high-quality potassium chloride in various
    concentrations. They are standardized using a conductivity meter calibrated with
    NIST potassium chloride.

    The 1413 μS/cm solution is the one best suited for general use. This solution is
    also available in combination kits with the pH 7 buffer for the easy calibration of
    multiparameter instruments
Hanna 1500PPM & 1413 uS-CM Calib. Solutions

    HANNA®' buffer solutions are prepared according to precise formulas and are
    standardized with a pH meter calibrated according to the NIST standards.

    All pH 4 solutions show batch number, expiration date and the correlation table
    between pH and temperature.

    pH 7.01 is the most widely used among all buffer solutions.
Hanna pH4 & pH7 Calibration Solutions

    HANNA® packet solutions are prepared according to precise formulas and are
    standardized with a pH meter calibrated according to the NIST standards. The 20
    mL sachets are single-dose and are ready to use.
