== Datasheet ==

=== 1. Introduction ===
The SENSBLUE RS-485 Dissolved CO2 Sensor Probe AT-SB-PROBE-CO2-P-5000-C1 is a gas detection module based on NDIR infrared absorption principle, which is suitable for detecting the concentration of carbon dioxide in aqueous solution. KWS-5000 adopts a patented optical cavity, adopts convection diffusion ventilation method and protective cover, which not only accelerates the gas convection diffusion speed, but also waterproof and breathable. Unique waterproof structure, detachable, easy to clean the outer casing of the sensor.

=== 2. Features ===

* Unique waterproof structure, can be disassembled;
* Lightweight housing for easy field installation;
* Rich interface, convenient for customers to choose;
* Provides zero calibration, sensitivity calibration and clean air calibration
