Temperature Meter with pH Electrode Diagnostic
*4 Meters in 1
*Fast response probe
The 9813-6 has all popular features of the 9813, plus C and the New Cal-Check Calibration feature! Now you can verify a clean, calibrated electrode anywhere in seconds. Accuracy is ensured with Automatic Temperature Compensation (ATC) and an advanced sensor which completely eliminates polarization and oxidation problems. HANNA also developed F.S.T. technology for HI9813-6, with this special security system, a system failure will force a fixed value close to pH 4, rather than pH 7, and render the problem clearer to the user. Cal solutions: 74-2520, 74-2525, 74-2530, 74-2535, 74-2540.
