The Model T700U is a microprocessor based calibrator for precision, trace-level gas analyzers. Using highly accurate mass flow controllers combined with compressed sources of standard gases, calibration standards are provided for multipoint span and zero checks using up to 4 gas sources. In addition to the features of the Model T700, the Model T700U is designed for the demanding requirements of trace-level measurements. The ability to calibrate and verify linearity for NO2 at levels below 50 ppb is difficult with standard calibrators.

• Trace-level calibration capability with O₃ and NO₂ generation down to 3 ppb
• High-accuracy mass flow controllers for precise gas dilution and delivery
• Dual operating modes for standard and ultra-low concentration calibrations
• Integrated ozone generation, photometer, and gas phase titration (GPT) functionality
• NumaView™ touchscreen interface with automated calibration sequencing and data management
• Supports up to four calibration gas sources for flexible multipoint calibrations
