Product Introduction

Hash HQ11D pH/ORP water quality detector from the United States

-Product Overview:

The HQ11D digital pH analyzer can be used with any standard pH IntelliCAL electrode. HQ11D uses a lot of software and technology, which is a very economical measurement method. Calibration data and calibration history can be carried along with each IntelliCAL electrode, allowing operators to switch calibrated electrodes between analyzers. The electrodes should be calibrated in a controllable environment and can be used on-site. Automatic detection of standard procedures and calibration reminders can ensure the accuracy of data. It can store a total of 500 data records by linking each measured sample ID, user ID, and electrode serial number.

-Instrument features:

●multi-purpose machine

A HQd multifunctional water quality detector can be connected to different electrodes. Used for measuring parameters such as pH, ORP, sodium, ammonium, ammonia, fluorine, nitrate, chlorine, conductivity, dissolved oxygen, etc.

●Multiple measurement methods

HQd portable water quality analyzer provides three reading modes, which can achieve measurement of instant reading, indirect reading, and continuous reading.

●Large screen, multi parameter, multi item display

The large dual channel display screen can not only show measurement parameters, but also display auxiliary information such as electrode model, instrument power, measurement date and temperature, sample and user ID.

●Humanized correction guide

The operation interface of HQd portable water quality 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 you can obtain the correct calibration results.

●Complete data traceability

The HQd series multifunctional water quality detector 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

HQd portable water quality analyzer provides USB interface, which can easily transfer data results to USB flash 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 just at a fixed temperature. For dissolved oxygen, when equipped with conductivity electrodes, the HQd portable water quality 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

The connection between the HQd portable water quality analyzer and the electrode is safe and waterproof. It can be used for both laboratory analysis and on-site analysis. When the light is dim, the instrument screen can emit background light and enlarge the font displayed on the screen. In addition, users can also choose a sturdy and durable on-site toolbox, which makes on-site measurements extremely convenient.
