2. Features
2.1. Description
The Model 600 series of NDIR analyzers incorporate a single-beam photometric system and a
detector with a microflow sensor assuring high reliability, sensitivity, accuracy, and stability.
The microflow detector is a sealed unit filled with the same gas as the component of interest
(CO, CO
2
, and CH
4
). The length of the sample cell determines the most sensitive range for
each component.
2.2. Features-General
The Model 600 series of NDIR analyzers have a 3 by 5 inch liquid crystal display and a 20 key
data/operation input keyboard. The 16-bit microprocessor control board consists of the MSR-
Card with 16 digital inputs, 16 digital outputs, 16 analog inputs and 4 analog outputs. The
analyzer can be manually operated from the keypad or remotely via TCP/IP or RS-232C
communications. After turning on the analyzer, it needs at least 30 seconds for initialization.
During this time, the screen is illuminated.
IMPORTANT TIP: When the analyzer is powered up, it defaults to access level 1 (User).
To operate ALL parameters, check the access level. See Section 5.
2.3. Features-General
High stability is provided by an improved photometric system, which assures less influence
due to contamination of the measuring cell and higher long-term stability than conventional
dual-beam analyzers.
•
A dual-chamber type detector effectively minimizes influence due to concomitant gas
components.
•
A microflow sensor within the detector features high reliability, long service life, very
low noise, and excellent resistance to vibration.
•
The easily serviced single-beam photometric system does not require delicate
adjustment of the optical-balance.
•
Simple construction assures reliable performance.
•
Modular component design simplifies maintenance. Independent elements are easily
removed for maintenance.
•
Low Power Consumption - The instruments are of energy-saving design with power
consumption as low as 30 VA.
