Water Quality Monitoring Tools: From Portable Devices to Stationary Systems

Recommend Several Excellent Water Quality Monitors

I. Portable Multi-parameter Detector (FT-SS07)

It covers all parameters and supports the detection of 12 parameters such as water temperature, conductivity, pH, ammonia nitrogen, dissolved oxygen, COD, turbidity, etc. It adopts all-digital electrode technology, with an accuracy of ±0.1pH (for pH detection) and ±2% (for dissolved oxygen detection).

It is equipped with a high-capacity lithium battery inside, which supports continuous operation for 8 hours. It comes with an IP66 protective case and is suitable for scenarios without a power source such as rivers and lakes.

It can be equipped with the self-developed ftiot operating system, supports multi-protocol communication such as RS485, TCP, and HTTP, and can achieve remote debugging through a 4G module.

II. Pole-mounted Online Monitoring System (FT-LSZ05)

This is a water quality monitoring station that does not require personnel on duty. It integrates a solar power supply system and MPPT power tracking technology, with a static power consumption of less than 1mA.

It is standardly equipped with ammonia nitrogen, dissolved oxygen, and turbidity sensors, and supports the expansion of parameters such as residual chlorine and total nitrogen through the Modbus protocol. It is mostly used in scenarios such as aquaculture ponds and urban sewage outlets.

The cloud is equipped with a B/S architecture cloud platform, which supports real-time viewing of historical data curves on the mobile phone side and triggers SMS alarms.

III. Miniature Automatic Water Quality Monitoring Station (FT-QSZ05)

This is for the monitoring of water supply pipelines and is specially designed for waterworks. It can detect 9 key indicators such as PH, turbidity, COD, and total nitrogen. It uses a COD sensor based on the UV254 absorption method with an anti-biological pollution design.

It has a built-in self-priming pump (flow rate of 1.8m³/h), a flow cell, and a 7-inch capacitive touch screen. It supports data export via a USB flash drive and is suitable for secondary water supply pipelines and direct drinking water terminals.

It has industrial-grade protection, with a 216 stainless steel box and an IP54 protection level, and can withstand an ambient temperature of 50℃.

IV. High-precision COD Special Analyzer (FT-ZS1S)

It adopts the UV254 absorption method, with a measurement range of 0-500mg/L and an accuracy of ±5%. It is equipped with an automatic cleaning brush to prevent the contamination of the optical window.

The basic model supports the detection of COD, ORP, and temperature, and can be expanded with modules such as dissolved oxygen and conductivity. It is suitable for the process control of sewage treatment plants.

It supports the MODBUS-RTU protocol and can be directly connected to a PLC or DCS system to achieve linkage control with aeration pumps and dosing equipment.

Purchase Suggestions

For scientific research and emergency detection, it is advisable to give priority to the FT-SS07, which stands out for its portability and the ability to cover all parameters.

For aquaculture and the supervision of rivers and lakes, the pole-mounted design and cloud management of the FT-LSZ05 are more suitable for long-term outdoor monitoring.

For the safety control of tap water, the miniature workstation mode of the FT-QSZ05 can seamlessly connect to the water supply pipeline network.

For industrial sewage treatment, the protocol compatibility and COD special analysis ability of the FT-ZS1S are more in line with the process requirements.
