In recent years, with the development of agricultural technology in China, vegetable greenhouse technology has been widely popularized and applied, and the number of greenhouses is increasing day by day For these vegetable greenhouses, the growth environment of their own crops, such as temperature and humidity, light intensity CO2、 Soil temperature and humidity need to be monitored and regulated to maintain crop growth in a suitable environment. Real time and accurate detection and regulation of these growth factors are important steps in achieving high-quality and high-yield vegetable production in greenhouses.

Hongrun's full range of instruments can be networked with the system to achieve data acquisition and monitoring management. At the same time, they can be used in conjunction with various actuators to perform PID regulation and control, alarm control, data acquisition, and other functions on electric heating equipment and electromagnetic/electric valves. The EMC design of the product complies with the relevant provisions of GB/T17626.2-11, and the product has obtained CE certification. The following is the application of Hongrun's full range of NHR instruments in the automatic monitoring system of sewage treatment plants. Through it, on-site measurement and control of liquid level, pH value, dissolved oxygen, turbidity, frequency, and pump operation status can be achieved.

The NHR-XTRM temperature remote monitoring instrument adopts advanced microprocessors for intelligent control. According to user needs, indicator instruments, recording instruments, regulators, etc. can be connected in series with the DC24V power supply in the output circuit of the XTRM instrument, outputting a current proportional to the highest temperature of the circuit for temperature indication, recording, or adjustment. Users can also check the temperature of the corresponding circuit one by one through the buttons installed on the panel. This product can perform up to four measurement signals during cyclic testing and can perform high-precision linear correction on temperature signals.

In the blood ward, there are high requirements for temperature, humidity, and lighting. In order to improve automation, a temperature and humidity monitoring system has been added to the air conditioning system of a blood ward in a hospital in Shanghai. The 15 inch Taiwan, China Willenton touch screen is used as the upper computer, and the Hongrun NHR series instruments are used for data acquisition and control output. Real time collection and display of temperature, humidity, and various switch values for air conditioning units, chiller units, auxiliary rooms, and various wards have been achieved.
