Introduction
Teledyne Analytical Instruments Series 4040, Methane/ Non-
methane Analyzer, is designed to measure the quantity of variety of
hydrocarbons present in the sample gas. The Analyzer is a
microprocessor controlled digital instrument based on Teledyne’s highly
successful Model 402R series analog Total Hydrocarbon Analyzer,
coupled with a gas separation Column and a switching valve. The
Analyzer allows for the separation and measurement of methane
hydrocarbon from the rest of the hydrocarbons in the low ppm range.
1.1 Main Features of the Analyzer
The Analyzer is sophisticated yet simple to use. A dual display on
the front panel prompts and informs the operator during all phases of
operation. The main features of the analyzer include:
1. Easy-to-use front panel interface that includes a red 5-digit LED
display and a vacuum fluorescent display (VFD), driven by
microprocessor electronics.
2. High resolution, accurate readings of concentration.
3. Versatile analysis with three user-definable analysis ranges.
4. Microprocessor based electronics: 8-bit CMOS microprocessor
with 32 kB RAM and 128 kB ROM.
5. 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.
6. Two adjustable concentration alarms and a system failure alarm.
7. Extensive self-diagnostic testing at startup and on demand.
8. RS-232 serial digital port for use with a computer or other digital
communication device.
9. Analog outputs for concentration and range identification (0-1
VDC standard and isolated 4-20 mA dc).
10. Superior Accuracy
