Supplier: Thomson Environmental Systems playlist_addCompare

The Model 400E Ozone Gas Analyzer is a microprocessor-controlled analyzer that uses a system based on the Beer-Lambert law for measuring low concentrations of ozone in ambient air.

Price Guide (Inc GST): POA

All instruments of the TAPI E Series include an extensive built-in data acquisition capability using the analyser's internal memory. This allows the logging of multiple parameters including averaged and instantaneous concentration values, calibration data and operating parameters such as flow, pressure and lamp intensity.

Stored data are easily retrieved through the serial port or optional Ethernet port via our APIcom software or from the front panel, allowing operators to perform predictive diagnostics and enhanced data analysis by tracking parameter trends.

The Model 400E UV Absorption O3 gas analyser combines lighter weight, rugged construction, ease of use, powerful diagnostics, modular design and outstanding performance to yield the ideal tool for today's air monitoring requirements.
