Multigas Calibrator, Model 146i

• Mass flow controllers dilute standard gases for the calibration of gas monitoring instrumentation
• Multiple calibration routines can be stored in calibrator memory
• Microprocessor-based calculation increases operator availability
• Unit can be operated remotely by a data logger or to perform multipoint calibrations
• Gas Phase Titration for Generation of O₃ and NO₂

• Maximum output: 1ppm at 6 SLPM
• Minimum output: 10ppb at 6 SLPM

Photometer System

• Full scale range: 100ppb to 5ppm user selectable
• Linearity: 1% of full scale
• Precision: 1ppb
• Response time: 180 seconds to 95% of target
• Minimum detectable limit: 3 ppb

iSeries Advantage:

• Ethernet connectivity for efficient remote access
