Calibration Solutions — Combination, pH, Conductivity, TDS & Cleaning Solutions

Our calibration solutions can be used with both of our meters – the 90 XL (used to calibrate dialysis machines) and the pHoenix XL (used to verify dialysate is at the correct pH), in addition to other applications. When you buy our solutions in bulk, you save.

  • NIST-traceable and 510(k) cleared
  • Choose from combination solution, pH buffer solution, conductivity solutions, total dissolved solids solution and cleaning solutions
