Comet SN253 – CO2 External Probe (0-50,000 ppm) with ELKA Connector, No Cable

Description

Comet SN253

• CO2 probe only no cable
• CO2 measuring range: 0 to 50,000 ppm
• Connector: ELKA
• For use with Datalogger U2422 and Multilogger M1440
• Extension cable must be ordered separately for use with U2422 and M1440

CO2 External Probe (0-50,000 ppm) with ELKA Connector, No Cable

The SN253 CO2 probe is a CO2 concentration sensor for Datalogger U2422 or Multilogger M144. A multiple-point CO2 and temperature adjustment procedure lead to excellent CO2 measurement accuracy over the entire temperature working range, this is a must for process control and outdoor applications.

The dual wavelength NDIR CO2 sensing procedure compensates automatically for aging effects. The CO2 module is highly resistant to pollution and offers maintenance-free operation and outstanding long-term stability. High precision capacitive polymer sensor ensures excellent long-term calibration stability and ultimate accuracy.

NOTE: Probe for connection to 1, 2, or 4 meter extension cable – must be ordered. The CO2 probes use a ‘big’ ELKA connector and cannot be directly connected – the Multilogger M1440 uses a MiniDIN connector and the U2422 uses a ‘small’ ELKA connector.
