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.

While Martek Instruments offers its own certified, unbreakable conductivity reference cells and pH sensor, the Mark 22 can also be used with any conductivity reference cell or pH electrode regardless of manufacturer. 

All Mark 22 accessories are sold separately. To purchase a bundle and save, view the Mark 22 Starter Kit here.

NEW:  Introducing the Mark 22 Calibrator Trade-in Program

We are now offering a trade-in program to help our customers turn in their old, tired Mark 22s for new ones.

Based on the age and condition of your Mark 22, you can receive credit towards the purchase of a new one. Below is the schedule:

                                    0-5 years old receive a $750-$1,000 credit

                                    6-10 years old receive a $500 credit

Simply return your Mark 22 to Martek with a note requesting a credit. We will evaluate each one to determine its age and condition and then inform you of your credit. It’s that simple. 

SPECIFICATIONS

*NOTE: The accuracy of conductivity measurements is dependent on appropriate cell constant in the scale of measurement and on the quality of the electrode.
