Mark 20 Water Quality Analyzer

- Easily calibrate and monitor up to eight channels
- Quick-disconnect terminal strips for adding or changing sensors to analyzer
- Slide-out chassis for calibrating analog outputs or for trouble-shooting

- Capable of remotely monitoring up to eight channels of conductivity and pH
- Automatic sensor detection at each of its eight channels and whether or not that channel has been correctly calibrated for that type of sensor
- Dual alarm set points at each configurable channel. Channels are continually scanned for alarm conditions. An alarm light on the front panel activates whenever any of the monitored channels recognize an alarm state.
- Well-lighted display presenting temperature, raw parameter data, and temperature-corrected parameter data simultaneously. This important feature allows the operator to immediately determine whether changes in parameter values are due to constituents in the process stream or simply temperature fluctuations.
- User-selectable temperature compensation formulas plus slope compensation for conductivity and pH measurements eliminate the need for additional modified circuitry or computer-generated correction factors.The Mark 20 resident processor easily applies these scientific formulas mathematically to the final readout measurement.
- Autoranging is performed on each of the three sets of dual conductivity ranges as well as through the set of four dissolved oxygen ranges.
- Differential analysis between any two channels of the same parameter provides instant performance evaluation of system efficiency for components such as dearators or condensate polishers.
- Standard RS232 digital serial port can be augmented with user-selectable analog outputs of 0 -1, 0 - 5 volt, or 4 - 20 mA for each separate channel. Up to ten Mark 20's (80 channels) can be multiplexed to one personal computer. The Mark 20 can even accept analog signals from other parameter analyzers and convert them to a digital output as well as indicate the data on its display.

The Martek Mark 20 includes the following items:
- Mark 20 Eight Channel Analyzer
