SMR78 Series
Transparency Analyzer
Our Transparency Analyzer monitoring system utilizes the high penetration capability of infrared light and its advantage in reducing scattering interference. Based on the principle of absorbance measurement, the analyzer detects changes in light absorption in water. By applying the correlation between turbidity and transparency, it accurately calculates the water transparency level.
The Transparency Meter transmits monitoring data directly through an RS485 communication interface, providing a simple, reliable, and cost-effective solution. It also supports remote status display, calibration, configuration, and fault diagnostics, enabling convenient integration into automated monitoring systems.
Featuring a robust IP68-rated dustproof and waterproof enclosure and a 1000 N high-strength Kevlar-reinforced cable, the system ensures durable and stable operation even in harsh environments. With a digital communication distance of up to 1.2 km, the analyzer can be directly deployed in reservoirs, rivers, drinking water facilities, and wastewater monitoring applications.

Technical Comparison
Technical Comparison
| Comparison Item | SMR78 Transparency Analyzer | Traditional Secchi Disk / Manual Visual Observation | General Turbidity Meter for Transparency Estimation | RTU / PLC Integrated Sensor Solution |
|---|---|---|---|---|
| Product Positioning | Online transparency analyzer for long-term in-situ transparency monitoring and digital data transmission | Manual on-site measurement tool suitable for temporary inspection | Indirect estimation of water transparency based on turbidity or scattering signals | Engineering integration solution requiring sensors, communication modules, and a control cabinet |
| Measurement Principle | Uses an LED 880 nm light source to calculate transparency based on light absorption intensity | Determines transparency based on the visible depth of a Secchi disk observed by the human eye | Uses turbidity scattering values as a reference for water clarity | Depends on the selected sensor and requires additional configuration for data acquisition and control logic |
| Online Monitoring Capability | Supports continuous monitoring with a response time of 3 seconds, suitable for long-term tracking of water transparency trends | Cannot provide continuous monitoring and requires personnel to visit the site regularly | Can monitor turbidity online, but transparency requires additional conversion or interpretation | Online monitoring is possible, but system installation and maintenance are more complex |
| Communication and Integration | RS485 digital interface with standard Modbus RTU, connectable to PLC/HMI or AQUAS data loggers | No digital communication; manual recording is required | Depends on the product; some models support RS485 or analog output | Custom integration is possible, but wiring, programming, and a control cabinet are required |
| Installation Method | Immersion installation, compatible with HMI, ECO, FLO, and other controllers/data loggers | Requires personnel to operate on site and does not support fixed automatic installation | Usually pipe-insertion, flow-through, or immersion installation, depending on the product | Requires planning for the control panel, power supply, signal cables, and on-site construction |
| Outdoor Protection | IP68 rugged submersible anti-corrosion enclosure for direct on-site installation | Not suitable for long-term fixed underwater monitoring | Depends on the product protection rating | Usually requires an additional outdoor control cabinet or waterproof enclosure |
| Maintenance Design | Sapphire glass optical window, nano-coating, and automatic cleaning brush reduce sludge and biofouling adhesion | Requires manual cleaning and operation and is easily affected by environmental conditions | Depends on the sensor design; if no cleaning mechanism is provided, maintenance frequency may increase | Requires simultaneous maintenance of the sensor, control cabinet, power supply, and communication equipment |
| Suitable Applications | Transparency monitoring in reservoirs, rivers, water supply, wastewater, surface water, and other applications | Short-term inspection and simple transparency verification | Turbidity monitoring or water quality trend reference | Large fixed water treatment or automated control systems |
Using an LED 880 nm light source, the analyzer measures the light absorption intensity of the water sample and converts it into transparency. The measurement range is 0–2 m, with a resolution of up to 1 mm. The device features an IP68 submersible anti-corrosion enclosure, RS485 Modbus RTU communication, an automatic cleaning brush, a sapphire glass optical window, and nano-coating, helping reduce manual inspection and on-site maintenance requirements. It is suitable for long-term online transparency monitoring.
