The HQD measuring instrument is connected to the IntelliCAL probe to automatically identify the measured parameters, calibrate historical data, and set methods, reducing errors and setup time.
The laboratory measuring instrument has a large backlit display screen, which can measure important water quality parameters and improve labor productivity.
All HQd measuring instruments provide an intuitive user interface for simple operation and accurate measurement.
The calibration data saved in the IntelliCAL intelligent probe ensures reliable measurement data.
● Standard configuration: Host, 4 AA batteries, power adapter, quick operation guide, user manual.

Product Introduction
◆.multi-purpose machine
An analyzer can be connected to different electrodes. Used for measuring pH, ORP, conductivity, dissolved oxygen, sodium, ammonium, ammonia, fluoride, nitrate, and chlorine.
◆.Multiple measurement methods
The analyzer provides three reading modes, which can achieve measurement of instant reading, indirect reading, and continuous reading.
◆.Humanized correction guide
The operation interface of HQd digital analyzer is simple and intuitive. It has calibration guidelines and standard procedures for inspection, greatly reducing calibration errors and simplifying the operation process. The calibration status indicator light and calibration reminder ensure that the correct calibration results can be obtained.
◆.Complete data traceability
The HQd series digital analyzer can automatically record the electrode serial number, current calibration data, user ID, sample ID, time, and date, and save them in the system's data log. Each measurement data can be associated with sample ID, user ID, electrode serial number, and other data, ensuring complete data traceability and report supervision.
◆.USB data transfer method
The analyzer provides a USB data interface, which can easily transfer data results to a USB drive and computer.
◆.Intelligent software system
The upgraded software allows users to customize pH standard solutions, that is, supports users to calibrate pH based on any pH standard solution they have, not just limited to a few fixed pH standard solutions. For conductivity, users can freely choose the reference temperature for temperature compensation, not limited to a fixed temperature. For dissolved oxygen, when equipped with conductivity electrodes, the analyzer can automatically calibrate the salinity of dissolved oxygen based on the measured salinity, without the need for manual input.
◆.Shared laboratory and on-site use
It can be used for both laboratory analysis and on-site analysis. All connections between the analyzer and electrodes are safe and waterproof. When the light is dim, the instrument screen can emit background light and enlarge the font displayed on the screen. In addition, a sturdy and durable on-site toolbox is optional. This makes on-site measurement convenient.
