SN253 external CO2 sensor, 0 … 50.000 ppm, ELKA connector, without cable COMET

Description

The SN253 external sensor with CO2 concentration sensor and measuring range 0 … 50,000 ppm is designed for use with the U2422 datalogger or the M1440 multilogger.

Includes ELKA connector. The multi-point CO2 and temperature adjustment process leads to excellent carbon dioxide measurement accuracy over the entire operating temperature range, which is essential for process control and external applications. The dual-wavelength NDIR CO2 detection process automatically compensates for the effects of ageing. The CO2 module is highly resistant to contamination and can operate without maintenance and has an extremely long stability.

The high-precision capacitive polymer sensor provides excellent long-term calibration stability and outstanding accuracy.

The probe for connection to a 1, 2 or 4 metre extension cable must be ordered separately. The CO2 probes use a “large” ELKA connector and cannot be connected directly – the M1440 multilogger uses a MiniDIN connector, U2422 and a small ELKA connector.
