Delivery time
In stock and ready to ship
The most focused and accurate water quality analysis tool on the market. For accurate, continuous, in-situ monitoring of ultrapure water quality parameters
The Martek Mark 18 Ultrapure Water Quality Analyzer provides laboratory accuracy in a single channel on-line instrument for continuous monitoring of high purity water quality. Designed to provide maximum value and flexibility, the Mark 18 can be adapted to monitor any water quality parameter simply by selecting the appropriate sensor and program. Data is displayed in precise engineering units on a large back-lit display while both digital and analog output signals are available for external recording equipment and control devices.
Designed to withstand harsh environments, the Mark 18 utilizes protected circuitry and a unique power supply to minimize electrical noise and interference commonly found in industrial climates.
