Product Launch | ATE2000DC Reagent-Free Full-Spectrum Water Quality Monitor

2026-11-12

Facing regulatory challenges such as hidden water pollution discharge, covert inspection of sewage outfalls, and water quality early warning in pipe networks, traditional water quality monitoring stations have long construction cycles, require mains power, and are visually obvious and easily damaged. To address this, Optosky has launched the ATE2000DC integrated reagent-free full-spectrum water quality monitor based on the mature ATE2000 full-spectrum monitoring platform. It highly integrates the sensing unit, ultra-low-power control system, large-capacity lithium battery pack, and NB-IoT communication module into a fully sealed housing—truly achieving “deploy and monitor.”

01 Product Overview

The ATE2000DC is specifically developed for covert water pollution monitoring scenarios. It inherits the core advantages of reagent-free full-spectrum detection. Based on UV-Vis full-wavelength absorption spectroscopy, dual-beam compensation, and concentration inversion algorithms, it analyzes and obtains target component concentrations. The device uses covert underwater in-situ monitoring and can output multiple parameters including COD, TOC, turbidity, color, TSS, nitrate, nitrite, total phosphorus, total nitrogen, ammonia nitrogen, and temperature. It is an “underwater sentry” for ecological environmental protection.

The entire unit adopts a barrel-shaped three-section integrated structure. The housing is made of 316 stainless steel with IP68 protection rating, allowing stable long-term operation when submerged underwater. The device innovatively adopts an externally controlled power-off management strategy, completely cutting power to the sensing unit between measurements. With a standard 30-minute measurement interval, it can achieve approximately 30 days of continuous battery life. The battery supports quick hand replacement, perfectly adapting to long-term unattended scenarios.

02 Core Highlights

Lithium Battery Integration, In-Situ Monitoring

No separate power supply, no water sampling, no water sample pretreatment, and covert installation. Quick deployment with only additional fixing.

Full-Spectrum Reagent-Free, Green Monitoring

Adopts spectral principles with no reagents and no secondary pollution to the environment. Can simultaneously detect more than 10 target parameters.

Dual-Beam Compensation, Outstanding Performance

Dual-beam compensation design is less affected by external environmental interference, with high sensitivity, high signal-to-noise ratio, and good linearity. Supports real-time online calibration.

Second-Level Response, All-Weather Continuous Monitoring

Fast response time with second-level rapid response. Supports over-limit alarms and scheduled data return, enabling all-weather continuous online operation.

Ultra-Low Power, Approximately 30-Day Battery Life

Large-capacity lithium battery pack (11.1 VDC / 50 Ah / 555 Wh) combined with an external power-off strategy achieves approximately 30 days of continuous battery life at a standard 30-minute measurement interval. Battery supports quick hand replacement.

Automatic Cleaning, Low Maintenance Cost

The probe is equipped with a cleaning motor for automatic maintenance-free cleaning, eliminating concerns for long-term underwater operation.

Pulsed Xenon Lamp, Ultra-Long Life

Uses a Hamamatsu pulsed xenon lamp, supporting 10⁹ measurements with a theoretical life of more than 10 years and high stability.

NB-IoT Wireless Communication, Cloud Management

Supports over-limit and scheduled data return, including time, concentration, device ID, battery status, and recent cached records. Local storage supports 10,000 records. Supports cloud platform remote manual acquisition, device wake-up, and algorithm deployment.

Compliant with Industry Standards

Complies with T/CWEC 13-2019 Technical Guidelines for Spectral Water Quality Online Monitoring Systems.

03 Working Principle

The device is based on UV-Vis full-wavelength absorption spectroscopy (180–1000 nm continuous spectrum). Characteristic components such as organic matter and nitrate in water produce absorption at specific bands. The system uses automatic dual-beam compensation (including turbidity compensation) to eliminate light source fluctuations and turbidity interference, and combines concentration inversion algorithms to achieve simultaneous analysis of multiple parameters such as COD, TOC, ammonia nitrogen, and nitrate—completing accurate quantification without chemical reagents.
