HQd Series Benchtop/Portable Multi-parameter Digital Analyzer, Hach (CAT#: STEM-AI-0677-YJL)

HQd Series Benchtop/Portable Multi-parameter Digital Analyzer, model HQd is manufactured by Hach. Hach's HQd series digital analyzers can currently detect 11 parameters, with standard, rugged and UItra electrode options. Hach's HQd digital analyzer has high measurement flexibility, very simple operations such as electrode replacement, and can automatically identify electrodes. The whole set of measuring devices includes various lnteliCALTM electrodes, which can measure pH, conductivity, dissolved oxygen (LDO), LBOD, ORP and sodium, ammonium, ammonia, fluorine, nitrate, chlorine.

One machine with multiple functions
Different electrodes can be connected to one analyzer. For the determination of pH, ORP, sodium, ammonium, ammonia, fluorine, nitrate, chlorine, conductivity, dissolved oxygen, etc.
Various measurement methods
The analyzer provides three reading modes, which can realize the measurement of push-to-read, indirect reading and continuous reading.
Humane Correction Guide
The operation interface of the HQd digital analyzer is simple and intuitive, with calibration guidelines and standard procedure checks, which greatly reduces calibration errors and simplifies the operation process. Calibration status indicators and calibration reminders ensure correct calibration results.
Complete data traceability
The HQd series digital analyzer can automatically record the serial number of the electrode, the current calibration data, user ID, sample ID, time, and date, and save them in the data log of the system. Each measurement data can be associated with the sample ID, user ID , Electrode serial number and other data are associated to ensure complete data traceability report supervision.
USB data transfer method
The analyzer provides a USB data interface, which can easily transfer the data results to the U disk and computer.
Fully intelligent software system
The upgraded software allows users to customize pH standard solutions, that is, supports users to correct pH according to any pH standard solutions they have, not just limited to a few fixed pH standard solutions. For conductivity, the user is supported to choose the reference temperature for temperature compensation arbitrarily, not limited to a certain fixed temperature. For dissolved oxygen, when equipped with a conductivity electrode at the same time, the analyzer can automatically measure dissolved oxygen according to the measured salinity. Make salinity corrections without manual entry.
Laboratory and field sharing
It can be used for both laboratory analysis and on-site analysis. All connections between the analyzer and electrodes are secure and watertight, and the instrument screen is backlit in the dark and fonts displayed on the screen can be enlarged. Plus, a rugged field tool case is optional. This makes on-site measurement extremely convenient.
