1. INTRODUCTION
1.1. M703E CALIBRATOR OVERVIEW
The Model 703E is a microprocessor-based ozone calibrator for calibration of ambient ozone analyzers, such as
the T-API M400E. The M703E features an internal ozone photometer that provides very accurate closed loop
feedback control of the ozone concentration.
As many as 50 independent calibration sequences may be programmed into the M703E, covering time periods
of up to one year. The setup of sequences is simple and intuitive. These sequences may be actuated manually,
automatically, or by a remote signal. The sequences may be uploaded remotely, including remote editing. All
programs are maintained in non-volatile memory.
The M703E design emphasizes fast response, repeatability, overall accuracy and ease of operation. It may be
combined with the Model 701 Zero Air Generator to provide the ultimate in easy to use, precise calibration for
your ozone analyzers.
Some of the exceptional features of your M703E Photometric O3 Calibrator are:
Advanced E Series electronics
Lightweight for transportability
Optional Ethernet connectivity
12 independent timers for sequences
Nested sequences (up to 5 levels)
Internal ozone generator and photometer allows use as primary or transfer standard
