Product Specification

CO2 Engine K30 STA
Sensor Module and OEM Platform

CO2 Engine K30 STA NDIR CO2 Sensor Module General
The K30 sensor platform CO2 Engine K30 STA can be customized for a variety of sensing and control applications. This platform is designed to be an OEM module for built-in applications in a host apparatus, and hence should be optimized for its tasks during a dialog between SenseAir and the OEM customer. K30 is a flexible product with 2 analog outputs and 2 digital outputs that can be configured with SADK or other custom software to meet your requirement.

Maintenance	Maintenance-free when using SenseAir ABC algorithm (Automatic Baseline Correction).

¹Accuracy is specified over operating temperature range at normal pressure 101.3 kPa. Specification is referenced to certified calibration mixtures. Uncertainty of calibration gas mixtures (+-2% currently) is to be added to the specified accuracy for absolute measurements.
²Notice that absolute maximum rating is 14V, so that sensor can be used with a 12V+-10% supply.
