TDS Calibration “Singles”

Use this TDS meter calibration solution to calibrate ANY conductivity or TDS meter. This calibration solution value is ideal for calibrating instruments used to test potable (drinking) water.

OAKTON Conductivity “Singles” pouches are convenient, air-tight pouches with high-precision calibration standards. Ideal for field use-take them to your test site for on-the-spot calibration. Pouches are labeled with equivalent values for ppm in KCl, NaCl and 442 and Conductivity values at 25°C and CAS numbers for “Right-to-Know” requirements.

All OAKTON Conductivity/TDS calibration solutions are cross checked using different test methods, premixed, and ready to use.
