Teledyne API T750U

Trace Level Portable Gas Calibrator

The Teledyne API T750U is a portable gas calibrator designed for precision calibration of gas analyzers using controlled dilution flow. It provides dilution air flow up to 10 SLPM and cylinder gas flow up to 200 cc per minute with ±1 percent flow measurement accuracy. The system generates ozone and nitrogen dioxide with minimum concentrations down to 3 ppb. It operates over an input pressure range of 20 to 40 psig and supports digital communication through Ethernet and serial interfaces.
