TAPI - Model T700U - Trace-Level Dilution Calibrator
From Gas Calibrators & Zero Air Generators
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.
Products Details:
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. To overcome this limitation, the Model T700U ozone generator operates in two modes; a high range with similar performance to the Model T700 ozone generator, and a low range, or “fractional” mode, for producing accurate ozone levels down to 3 ppb. To ensure the highest accuracy of NO2 output, the calibrator measures the ozone concentration prior to performing a GPT, and the range is selected automatically by the Model T700U based on ozone concentration and flow specified by the user.
All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports either locally or by remote connection.
The Model T700U 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.
