- Fully programmable alarms and analogue output
The Z230 zirconia oxygen analyser measures a wide range of oxygen concentrations (from percentage levels to a few ppm) in clean gases. It is a single-unit system based on a zirconia oxygen sensor which provides a wide dynamic range with minimal interference from other gases. The unique cell and heater design gives very fast warm-up times, rapid response, and long sensor life. A wide choice of range and sampling options is provided to produce virtually ‘custom-built’ systems.
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.
