DigiGas-OX Oxygen Concentration & Partial Pressure Sensor, SDI12, RS485 Interface

Time:2024/07/09 View:256 Category:Gas Concentration Category:Measurements Category:Products Category:SDI-12 Products Category:SDI-12 Sensors

　　DigiGas-OX oxygen sensor measure ambient oxygen partial pressure (ppO2) levels using the principle of luminescence quenching by oxygen, to offer high accuracy at an unmatched price and smallest form factor. The sensor is applicable for science research, routine weather monitoring, air conditioning, environment monitoring etc. The SDI-12 output provides universal compatibility with any SDI-12-enabled data logger and low power applications, or use a RS485 physical interface for applications that require long cable runs or many sensors.
