1 Introduction

Model 3020T

 

 

 

 

 

 

 

 

 

Advanced Micro-Fuel Cell, redesigned for trace analysis, has an expected life 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 0-10 ppm through 0- 250,000 ppm) allow best match to users process and equipment.

Air-calibration range for convenient spanning at 20.9 %.

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.

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.

1.4Model Designations

3020T: Standard model.

3020T-C:In addition to all 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 3020T electronics, to automatically switch between gases in synchronization with the analyzer’s operations

3020T-F:Flame arrestors for Groups C and D installed.

3020T-G:Flame arrestors for Groups C and D, & -C option, installed.

3020T-H:Flame arrestors for Group B (hydrogen) installed.

3020T-I:Flame arrestors for Group B, & -C option, installed.

All of the above options are available in combination.
