The C255 Industrial Combustion Analyzer is designed for commercial and industrial environments. The device is equipped with a high-range (10,000 ppm) H2-compensated CO sensor that has an expected five-year sensor life. The C255 can be upgraded with either a 100-ppm low-NOx sensor, or standard 1000-ppm NOx sensor for compliance requirements. In addition to the combustion analysis functionality, the C255 also features differential manometer and differential temperature functions that operate in tandem or independently from combustion tests. The C255 is also available as a kit (C255KIT) and includes an infrared thermal printer, spare paper roll, ac adapter/charger, thermocouple temperature probes, and inlet tubes.
