The Model T750U is a portable, 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 calibrations. The T750U 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.
