5.The monitoring equipment has local and remote calibration functions, and is equipped with a pre-treatment system (dust removal, water vapor and other impurities) to silence the sound with one click.
6.The main interface of the monitoring equipment displays the real-time curve for the past 60 seconds, and the concentration values are displayed in numbers and graphics.
7.Monitoring equipment can be installed on poles or wall-mounted.
8.Life cycle management system, the system manages the life of main components and can provide alarm prompts based on the set remaining life;
9.The equipment needs to be equipped with a color touch screen to facilitate debugging operations;

4.Product installation
Fengtu Technology’s odor gas monitoring system product construction and installation plan
HJ 664-2013 Technical specifications for the layout of ambient air quality monitoring points (Trial)
1.Installation environment
The installation environment should try to comply with the operating environment requirements of the environmental monitoring system (including ambient temperature, ambient humidity, and environmental pressure).Areas with mechanical vibration, strong electromagnetic radiation, excessive air (wind speed) flow, and excessively high ambient temperature and humidity should be avoided as much as possible.Too fast air flow will affect the detection response time and detection results.Excessive ambient temperature and humidity will affect the detection results and the service life of the sensor.
2.Installation location
The overall principle should take into account factors such as the diffusion space of the gas to be monitored, wind direction, ambient temperature, ambient humidity, closedness of the monitoring area, process pressure and distribution of surrounding equipment.Priority should be given to areas where personnel are on duty or where people are frequently stranded.
Guided installation
1.Pre-embedded foundation and construction with embedded parts
1.The middle frame of the floor cage is square 21cm*21cm, 51cm high, and the distance between the outer hooks at the bottom is 31cm, as shown in Figure 1.The size of pre-embedded construction shall not be less than 50cm*50cm, and the depth shall be 40-43cm.
Figure 1
2.Find the horizontal position and place the embedded parts in the appropriate direction, with one front facing south.When pouring embedded parts, be careful not to pour concrete into the wiring pipe or on the studs of the embedded parts.The position of the embedded parts in the pit should be straight and not skewed, and the embedded parts should be fixed to prevent the position of the embedded parts from changing when pouring concrete.As shown in Figure 2.
3.Wiring, conduct reasonable wiring in advance according to order requirements, including power cords.If wiring is required, before pouring concrete, a wiring pipe needs to be placed.It is usually a plastic pipe made of PVC.The diameter is customized according to the size of the power supply cable.The wiring pipe must be 5cm higher than the reserved hole in the center of the embedded part, and the other end must be able to be connected to the corresponding equipment.
