Environmental Compliance Huanqitong HQT-W series online water quality monitoring system for COD, ammonia nitrogen, TP, TN, pH, DO and turbidity

Overview

Water quality online monitoring systems are deployed at surface water sections, drinking water sources, wastewater treatment plant discharge outlets and industrial park pipelines that require continuous automatic monitoring. The cabinet-type analyzers automatically sample, digest, measure and report COD, ammonia nitrogen, total phosphorus, total nitrogen, pH, dissolved oxygen and turbidity, uploading data via 4G / 5G or Ethernet to environmental platforms for real-time alarm and total-volume control.

The HQT-W series supports single and multi-parameter configurations with sampling pre-treatment, auto-cleaning, quality control, temperature control and surge protection built into the cabinet β€” suitable for riverside, pump station and park outdoor conditions, with OEM / ODM customization.

FAQ

Which parameters can be monitored?
COD, ammonia nitrogen, total phosphorus, total nitrogen, pH, dissolved oxygen, turbidity and conductivity, in single or multi-parameter combinations with customizable ranges.
Can data upload directly to environmental platforms?
Yes. HJ212-2017 protocol support with 4G / 5G / Ethernet upload to provincial, municipal and park environmental platforms for compliance monitoring.
How often is maintenance required?
Reagents typically replenished monthly; pipelines auto-clean; routine inspection every quarter. Remote diagnostics & QC reduce on-site visits.
Can it be customized for the site?
Yes. Huanqitong supports OEM / ODM by parameter, range, cabinet size, power (mains/solar) and installation environment.
