Martek Instruments
Introduces a Technological Breakthrough
in Water Quality Analysis:
VALUE.
Today, water quality has never been more important. Whether it's extended boiler life, higher chip yields, or drug uniformty, pure water makes economic good sense. And so does Martek.

Compare these features of the Mark 20 with other systems and see what we mean:

•Eight channel capacity for measuring conductivity/resistivity, pH, dissolved oxygen, ORP, and % acid & caustic measurements in any combination
•User-selectable temperature compensation formulas and slope coefficients for conductivity and pH
•Dual alarms, user-selectable analog outputs, RS232 digital output
•Differential analysis between sampling points
And for maintaining on-line accuracy, there's nothing like the Mark 22 In Situ Calibrator:

•Completely portable - operates off of internal batteries or AC power
•Calibrations traceable to NIST and ASTM standards
•Measures both conductivity and pH without grab samples
•Internal data logger with RS232 digital and 0-1 volt analog outputs


As for satisfaction, Martek provides that too with a thirty day, money-back guarantee, one year comprehensive warranty, and the best service support in the business.
