Teledyne Gas Calibrators & ZAG- T753U

Published on : Tuesday 30-11--0001

The Model T753U is a portable, microprocessor based precision Calibrator for Ozone gas instruments and sensors. Using a sophisticated Ozone generation system, combined with a sensitive photometer and pneumatic design, the T753U produces stable and reliable concentrations of Ozone in a convenient and rugged package based on our popular T750/U Portable Multigas Calibrator platform. The T753U is housed in a high-density, molded travel case which includes an integral handle and wheels for durability and ease of use in the field for virtually any application. An internal zero air option extends the T753U's capabilities to also provide a clean and dry source of zero air, eliminating the need for a separate source of zero air. The internal zero air source module contains a software driven electronic inlet valve manifold allowing the calibrator to automatically switch between internal and external zero air sources depending on the application needs.?

 

The T753U Portable Ozone Calibrator's performance is characterized by our own Model T265 Chemiluminescence O3 Analyzer; a US EPA Federal Reference Method (FRM) for Ozone. With an interference-free Ozone measurement and best available lower detection limit (LDL) of < 0.3 ppb, the T753U performance is proven by the most sensitive Ozone gas analyzer technology available.

 

All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, and flexible I/0.  All instrument set up, control and diagnostic information is available through the front panel, or via RS232, Ethernet, or the optional USB com port, either locally or by remote connection

 

The Model T753U comes with NumaView ™ Software.  NumaView™ Remote PC software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView ™ software.?
