Water quality monitor

Introduction

A water quality monitor is an instrument used for the continuous or the periodic monitoring of the water quality parameters, such as the pH, the conductivity, the dissolved oxygen, the turbidity, the temperature, and the other parameters, and it is used in the environmental monitoring, the water treatment, the wastewater treatment, the aquaculture, and many other applications. The water quality monitor consists of one or more sensors or probes that measure the parameters, a data acquisition and a control unit, a display, and, in the online models, a communication system, and it measures the parameters and provides the data for the assessment and the control of the water quality; the water quality monitor may be a portable instrument for the field measurements, a benchtop instrument for the laboratory, or an online system for the continuous monitoring, and it may be a single-parameter or a multi-parameter monitor, and it provides features such as the automatic calibration, the data logging, the alarms, and the communication with the control systems; the water quality monitor is used for the monitoring of the quality of the drinking water, for the monitoring of the rivers, the lakes, and the groundwater, for the monitoring of the influent and the effluent of the wastewater treatment plants, for the monitoring of the aquaculture water, for the monitoring of the industrial process water, for the compliance with the regulations, and for many other applications. Water quality monitors are used by the environmental agencies, by the water utilities, by the wastewater treatment plants, by the aquaculture operators, by the industry, and for many other applications. With their monitoring of the water quality, water quality monitors are essential for the water quality management.

FAQ

Q1: What scenarios is this monitor used for?

A: It continuously measures parameters such as pH, dissolved oxygen, turbidity, conductivity and temperature in wastewater, drinking water and process water, providing online readings and alarms.

Q2: What standards does it comply with?

A: It follows ISO/IEC 17025 methods, EPA and Standard Methods, related ISO and GB/T standards, with probes calibrated traceably.

Q3: What is the warranty?

A: The monitor carries a 12 to 24 month warranty covering the controller and probes. Membranes and reagents are consumables. Damage from immersion beyond rating or unauthorized repair is excluded.

Q4: Is it hard to operate?

A: Operation requires trained staff for installation, calibration and maintenance. We provide a manual and training.

Q5: What is the lead time?

A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Q6: Is calibration required?

A: We recommend verification against traceable standards at regular intervals, typically every 6 to 12 months, and keeping calibration records for audit purposes. The manual describes the procedure, and reference standards are available from us. Accredited third-party calibration can also be arranged on request.

Q7: Are consumables universal?

A: Reagents and membranes are universal or model-specific. Ongoing cost includes probe maintenance.

Q8: Can it be customized?

A: Yes, several configurations are available. Options include parameter channels, data logging, telemetry and mounting. We can discuss further custom requirements, confirm feasibility and advise any effect on the schedule before the order is confirmed.

Q9: Is installation included?

A: Standard delivery includes the monitor and manual. On-site installation and training are available.

Q10: What waters are compatible?

A: It handles waters within probe ranges, excluding incompatible chemicals or severe fouling without pretreatment. Providing the relevant details beforehand allows us to verify fit and helps avoid selecting an unsuitable configuration.
