Z230

A large multi-digit auto-ranging LCD is used to display measured concentrations and also user adjustable parameters during alarm configuration procedures. A fully bi-directional RS232 port is provided to allow the analyser to communicate with most proprietary micro controllers and, when used with the supplied software, gives full remote control capability. Two alarm channels, user configurable for high, low or off states and hysteresis, each provide one set of volt-free changeover contacts. They can be set to any concentration within the span of the instrument. A choice of two analogue outputs is provided, 0 to 5V or 4 to 20mA, each with several preset ranges. The standard sampling system is a simple needle valve and flowmeter. Options include: sample pump, fast flow loop system, syringe injection port. We also supply a range of sample conditioning accessories to cater for most sample sources.
