• Building a monitoring station buildingThe area should not be less than 3m×3.5m=10.5m²The specific size will be adjusted based on the number of devices. The monitoring station shouldapproachSampling point（Within 20 meters is preferred）. The height of the room floor is 20cm higher than the ground level, and the distance from the pollution source isThe gap is4mwithinThe monitoring station building is not directly constructed above the pollution source (otherwise it will result in severe humidity exceeding the standard). On the side close to the pollution source, leave a diameter close to the ground10 centimetersThe through-hole facilitates the entry and exit of water pipes (each device has 3 water pipes in and out). The monitoring station building is now in a dedicated room, with dedicated personnel for safekeeping and maintenance.
• This product is easy to measure,The sample to be tested does not require any pre-treatment. Simply insert the water sample lifting tube into the system water sample to measure the total nitrogen concentration. The device has a large measurement range of 0-500mg/L TN, and this method is mainly used for online automatic monitoring of total nitrogen concentration in waste (sewage) discharge point sources, surface water, etc.
