Carbon monoxide CO/ sulfur dioxide SO2/ hydrogen sulfide H2S signal processing plate (voltage type) +9~24V



  1. Power supply: +9V~25V;
  2. Signal output: linear analog signal (the output can be adjusted, suggestion: 0~4.5V, and due to the difference of the probe, a single device needs to use calibration gas and acquisition application software to correct the linear slope);
  3. Power-off control: low-level effective (<0.5V), mainly used for range overload protection, and interval collection applications that need to save energy (such as battery power supply). After the power is turned on again, a stable time is required (5~ 10 minutes) before collecting data!
  4. Sensor probe: suitable for 3 series and 4 series three-electrode sensors, read the introduction of each probe in the shop in detail, and when the probe is connected for the first time, it takes 5-10 minutes to stabilize!


  1. we also provide supporting probe service;
  2. Support customized services; (analog output, digital output, wireless acquisition, touch screen acquisition, host computer monitoring, etc.)
  3. Schematic diagrams, PCB, source code services are not provided for direct-sale products in stores;
