The Martek Mark 25 Ultrapure Water Conductivity Analyzer, also known as the "Martek Miracle Worker", is a highly accurate, simple-to-use monitoring system that provides continuous monitoring of up to four ultrapure water sample points at an affordable price.

Designed to provide maximum performance and value, the Mark 25’s ability to monitor up to four sample points along with a full complement of output capabilities allows the operator to customize the system to any application. A large, bright 4 digit LED display presents data and setup options quickly while DB-9 connectors and removable terminal strips allow for quick sensor, recorder, and alarm hookups. There’s even an ON/OFF switch located on the rear panel. 

Installation and calibration are easy and require a minimum of experience. Housed in a standard ¼ DIN enclosure, the Mark 25 easily replaces inoperative or obsolete equipment without modification to existing sample panels. And, with a five year warranty for the analyzer and a life-time warranty for the conductivity sensor, the Mark 25 is designed for years of worry-free service.
