1 Introduction

Model 3000TA-XL-EU

 

 

 

 

 

 

 

 

 

Advanced Micro-Fuel Cell, designed for trace analysis, has a 0-1 ppm low range with less than a 0.2 ppm offset and six months warranty and an expected lifetime of one year.

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- 250,000 ppm) allow best match to users process and equipment.

Air-calibration range for spanning at 20.9 % (209,000 ppm) available.

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.

Two way RFI protection.

RS-232 serial digital port for use with a computer or other digital communication device.

Four analog outputs: two for measurement (0–1 V dc 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.
