Ultrameter II model delivers the performance of ±1% of reading (not merely full scale). This high level of accuracy has been achieved through advanced four-electrode conductivity cell technology, a unique pH/ ORP sensor, and powerful
microprocessor-based circuitry. With displayed values of up to 9999, the full four-digit LCD ensures resolution levels
never before possible in such affordable instruments. Factory calibrated with NIST traceable solutions, each
Ultrameter II may be supplied with both certification of traceability and NIST traceable solutions for definitive calibration
The Myron L® Company FCE function reports FAC quickly and accurately by measuring ORP, the chemical characteristic of chlorine that directly reflects its effectivity, cross-referenced with pH. Both DPD kits and colorimeters may tell the user the FAC value of the sample in the test tube, but since the chemistry of that sample is quite different from the source water being analyzed, the results are imprecisely related to actual disinfection power. The Myron L® Company FCE function measures the real, unaltered chemistry of source water, including moment-to-moment changes in that chemistry.
