Understanding the functional characteristics of each component of the environmental water quality detector is essential for better use
Date: 2025-12-23Read: 7
Environmental water quality detector is used for real-time or rapid determination of key physical and chemical parameters in water bodies, such as pH, dissolved oxygen, conductivity, turbidity, etc COD、 The integrated analysis equipment for ammonia nitrogen, total phosphorus, etc. is widely used in surface water monitoring, sewage treatment, drinking water safety and other fields. The multi parameter, highly sensitive, portable/online compatible characteristics of the environmental water quality detector stem from the precise collaboration and intelligent integration of multiple functional modules.
1、 Multi parameter sensor array
PH/ORP electrode: using low impedance glass film and Ag/AgCl reference system, fast response, anti pollution, measurement range 0-14pH, accuracy ± 0.01;
Optical dissolved oxygen (DO) probe: based on the principle of fluorescence quenching, no membrane replacement required, maintenance free, range 0-20mg/L, accuracy ± 0.1mg/L;
Turbidity sensor: 90 ° scattered light method combined with infrared LED effectively eliminates chromatic interference, with a range of 0-1000NTU;
Conductivity/temperature composite probe: Four ring graphite electrode automatic temperature compensation, range 0-200mS/cm, suitable for high salt wastewater;
Optical modules for COD/ammonia nitrogen (some models): equipped with a built-in UV visible spectrometer, which quantifies characteristic absorption peaks without the need for chemical reagents (test free dosage form) or pre made reagents (colorimetric type).
2、 Intelligent data processing unit
The embedded microcontroller collects real-time signals from various sensors, performs automatic calibration, cross interference compensation (such as the effect of temperature on pH), data filtering, and unit conversion; Support multi-point calibration storage to ensure long-term stability.
3、 Human computer interaction and communication module
Display screen: high-definition LCD or touch screen, real-time display of multi parameter curves and alarm status;
Data output: Standard RS485 (Modbus), 4-20mA analog, optional Bluetooth/WiFi/GPRS, enabling remote monitoring and cloud platform integration;
Storage function: The built-in memory can record thousands of sets of historical data and supports USB export.
4、 Protection and power supply system
The shell is made of IP67 grade engineering plastic or stainless steel, which is dustproof, waterproof, and corrosion-resistant;
Power supply compatible with DC12V/24V, lithium battery (portable) or solar energy (field station), with a range of over 72 hours;
Self cleaning device (online type): Regularly activate ultrasonic waves or air brushes to prevent biological attachment from affecting the optical window.
5、 Calibration and maintenance design
Quick plug-in sensor design, easy to replace on site;
Automatic reminder of calibration cycle (such as pH every 30 days, DO every 60 days);
Modular structure reduces maintenance costs and downtime.
