and features a high accuracy, multiple functions
and easy operation through use of a microprocessor. It is
housed in an easy-to-use horizontal case (can be flush
mounted on panel, mounted on 19 inch rack, placed on table
top), or vertical case (can be flush mounted on panel,
mounted on wall).
The analyzer provides a performance superior to the con-
ventional double-beam system, is easy to maintain, and offers
an excellent long-term stability. It is thus optimum for con-
tinuous measurement in the combustion control of various
industrial furnaces, in research on garden-plants, and so on.

FEATURES
1. The use of a microprocessor provides high accuracy,
multiple functions and easy operation.
• Zero and span calibration is accurate and easy just by
pressing the calibrating keys.
• A self-diagnosis function is included.
• An automatic calibrating function can be provided as
an option.
• Range can be changed over by a external signal as an
option.
2. An improved optical system provides long term stabil-
ity, and there is a minimum of drift caused by contami-
nation of the measuring cell, so the long-term stability
is excellent.
3. Adopting a serial dual-layer type of transmission detec-
tor minimizes remarkable the interface from other gas
components.
4. Easy maintenance.
The single-beam photometric system uses a sample cell
only and eliminates the necessity of delicate adjustment
for optical balance. The instrument is designed as a
unit of simple construction featuring easy maintenance
and checks.
