offset and six months warranty and an expected lifetime of more than three years. 0-1 ppm range is possible too.
•No reference gas required
•Versatile analysis over a wide range of applications.
•Microprocessor based electronics: 8-bit CMOS microprocessor with 32 kB RAM and 128 kB ROM.
•Three user definable output ranges (from 0-1 ppm through 0-250 ppm) allow best match to users process and equipment.
•Auto ranging allows analyzer to automatically select the proper preset range for a given measurement. Manual override allows the user to lock onto a specific range of interest.
•Two adjustable concentration alarms and a system failure alarm.
•Extensive self-diagnostic testing, at startup and on demand, with continuous power-supply monitoring.
•CE compliance
•RS-232 serial digital port for use with a computer or other digital communication device.
•Four analog outputs: two for measurement (0–1 VDC and Isolated 4–20 mA DC) and two for range identification.
•Convenient and versatile, steel, flush-panel or rack- mountable case with slide-out electronics drawer.
1.4Model Designations
3000ZA: Standard model for sample under pressure
3000ZA-C: In addition to all the standard features, this model also has separate ports for zero and span gases, and built-in control valves. The internal valves are entirely under the control of the 3000ZA electronics to automatically switch between gases in synchronization with the analyxer’s operation.
