Mark 22 Portable Water Quality Analyzer
The Mark 22 is the easiest way to measure conductivity and pH for ultrapure water processes in one portable package. Also known as the Mark 22 Calibrator, it is a completely portable analyzer capable of verifying the performance of on-line conductivity and pH monitors. Designed to eliminate grab sample analysis and the inherent errors due to carbon dioxide contamination, the Mark 22 can be calibrated in the laboratory to traceable NIST and ASTM standards, then carried to the sample panel for direct measurement of the sample stream. This light weight analyzer contains its own rechargeable battery power supply, internal clock, memory, and both analog and digital communications port. The Mark 22's large back-lit display provides both raw and temperature-compensated data in direct engineering units while its menu-driven software makes calibration and data logging easy and straightforward.
