  AAQMS Air Quality Monitoring systems It will monitor the air quality of a city on a real-time basis. It will continuously measure air pollutants throughout the year in a continuous manner. The air pollutants measured are as follows: SO2, NO, NO2, NH3, CO, O3, CO3, VOC, PM10, and PM2.5. the instrument can also measure other types of pollutants The AAQMS measures PM10 and PM2.5 in real-time and displays the results on a monitor in the form of a graph. The monitor also shows various alarms in case of excessive pollution The AAQMS can be used in two different ways: as a standalone device, or as an interface connected to the computer The Air Quality Analyser (AAQMS) can be easily installed at any place where you want to monitor the concentration of particles in the air, such as in homes, offices, schools, hospitals, etc. You can use the Air Quality Analyser as a standalone device or connect it via USB to your computer to monitor the air quality on your computer screen in real-time...

  A piezometer is basically a tube that is inserted into an aquifer. The top of that tube has an element that changes in response to groundwater pressure. When there’s less pressure, such as when water levels are higher, there’s more space inside the tube. When groundwater levels drop and there’s more pressure on top of that element, it gets pushed down further into (or above) the tube. GWL VE300 Series  Piezometers  liquid level transmitter is put into the liquid. The water pressure eats the position of the transmitter acts on the diffused silicon sensor through the pilot hole. The liquid level signal can be obtained by measuring the pressure. After the sensor samples the liquid level signal, it is transported first. FEATURES : Anti-reverse connection,electrostatic protection,wide voltage power supply:DC730V Communication method: RS-485 Communication protocol: standard MODBUS-RTU protocol Communication distance: up to 2000 meters Stable and reliable:industrial-grade sin...
