Gas Filter Correlation N2O Analyzer

Product catalog summary

Overview: The Model 320E is a Nitrous Oxide (N2O) analyzer that utilizes the Gas Filter Correlation principle for accurate and stable measurements. It determines sample concentration by measuring infrared light absorption in a multi-pass sample cell.

Specifications: The analyzer offers user-selectable ranges from 0-1 ppm to 0-1000 ppm. It supports dual ranges and auto-ranging in ppm and mg/m³. Key performance metrics include zero noise (<0.02 ppm RMS), span noise (<0.5% of reading RMS), and a lower detectable limit of <0.04 ppm. The device exhibits minimal zero drift (<0.1 ppm/24 hours) and span drift (<1% of reading/7 days). It has a rise and fall time of <30 seconds to 95% and maintains linearity within 1% of range.

Design and Features: The Model 320E features a gas filter wheel for N2O-specific measurement, ensuring high sensitivity and low interference. It includes multi-tasking software for real-time monitoring and automatic alarms. The device supports data logging with up to 999,999 records retrievable via RS-232, Ethernet, or front panel. It is constructed for durability and ease of maintenance with modular components.

Outputs and Connectivity: The analyzer provides analog outputs (10V, 5V, 1V, 100mV) and supports serial outputs via RS-232 and optional RS-485 or Ethernet. It includes digital status outputs and optional 4-20mA current output.

Physical and Power Specifications: The Model 320E operates within a temperature range of 5 - 40˚C, with dimensions of 7” x 17” x 23.5” and a weight of 40 lbs. It requires a power supply of 100V - 120V or 220V - 240V, 50/60 Hz, 250W.

Additional Options and Accessories: Optional features include rack mount brackets, 4-20mA outputs, multi-drop RS-232 connection, and concentration alarms. Accessories available are RS-232 cables, expendables kit, and spare parts kit.

Warranty and Support: The Model 320E comes with a standard two-year warranty and offers free customer support via telephone and email for the instrument's lifetime.
