Serrax Technologies LLP

This analyzer measures CO₂ and O₂ levels using NDIR technology for CO₂ and an electrochemical sensor for O₂, ensuring stable and accurate readings. It delivers fast results with a response time of less than 30 seconds (T90) and operates at a constant flow rate of 100 cc/min.

The unit features an in-built LCD display that updates every second for real-time monitoring. Data is stored in 4 GB internal non-volatile memory, sufficient for several months, with a user-programmable logging interval from 1 minute to 1 hour.

The analyzer supports annual multi-point calibration using an in-house gas dilution facility. Powered by a rechargeable battery, it provides up to 8 hours of continuous operation, making it suitable for both laboratory and field use.

Serrax NPM260 Nitrogen Analyzer is a portable, high-accuracy instrument used to measure nitrogen purity in industrial and laboratory applications. It is designed for fast response, reliable performance, and easy operation in field and plant environments.
