18 ~ 36V Chlorophyll Meter For Water Chlorophyll Measuring


Brief Introduction


1. Chlorophyll is an important photosynthetic pigment in plant photosynthesis, which is insoluble in water and itself is not harmful to the environment, but water quality chlorophyll is an important indicator for estimating phytoplankton biomass, and the primary productivity of water bodies and eutrophication level can be grasped by measuring the chlorophyll content of phytoplankton in water, and in environmental monitoring, chlorophyll content is one of the indicators for evaluating the eutrophication of water bodies.


2. The DUC chlorophyll meter is a single-parameter controller used for the measurement of chlorophyll with the CHL sensor. Each controller will be pre-installed with a set of embedded software to adapt to different chlorophyll digital sensors. By connecting various different types of DRFN chlorophyll digital sensors, the measurement needs of different scenarios can be realized.


3. This CHL analyzer is equipped with RS485 Modbus RTU, RS485 Modbus RTU provides a stable and reliable communication solution suitable for industrial environments, enabling different types of equipment to communicate and control each other, which is beneficial to the integration and management of industrial automation systems.

RS485 allows multiple devices to be connected to the same bus and perform data transmission and control through serial communication protocols, making the integration between devices simpler and more flexible.

RS485 uses differential signal transmission, which can resist electromagnetic interference in industrial environments and ensure stable data transmission.

RS485 can support relatively long communication distances, allowing devices to be distributed in distant locations while maintaining reliable communication.

Modbus RTU is a widely used communication protocol. Its standardization allows devices from different manufacturers to communicate with each other, increasing the interoperability and compatibility of the devices.


4. The DUC2-CHL-S-D chlorophyll meter has a 128*64 large-screen LCD display, Chinese and English language display, rich content, to meet the different needs of users.


5. This instrument can query the working status of the sensor, including the serial number of the sensor.


6. This CHL measuring instrument can simultaneously meet the needs of users for detection, control, and remote data transmission, with rich output settings.


7. It is equipped with a two-wire RS485 interface, the communication protocol is MODBUS RTU, and supports JSON text data format.

Advantages Of The Chlorophyll Meter

  • This DUC chlorophyll controller can stably collect the data uploaded by the sensor in a special encrypted communication method, and display the data in real-time on the display screen, which is convenient for users to read.

  • The enclosure protection grade of the CHL controller is IP66. This material can effectively isolate the pollution and corrosive gas from the external environment.

  • This digital universal controller is equipped with a list of settings for the controller and sensor, and the user can quickly and in detail master the list of configuration parameters.

  • The chlorophyll meter has a clock function and a historical data recording function, which can record 14,000 historical data, and the recording interval can be set between 1 and 999 minutes.
  • Its menu password can be set to facilitate user's data confidentiality.

  • The shell material of the CHL instrument is reinforced ABS, the shell is strong, corrosion-resistant, and wear-resistant. The overall size of the DUC CHL analyzer is 144*144*120mm, and the user can choose a variety of installation methods such as wall-mounted installation, pipe clamping installation, and panel installation.

  • The controller has a power-off protection configuration, and the parameters can be kept indefinitely.
