實驗室水質分析主機與電極 HQ440d系列 pH電極與氟離子選擇電極 Drinking Water Lab Package with PHC281 pH Ultra and ISEF121 Fluoride ISE Electrodes
Hach HQd 系列便攜式水質分析儀目前可檢測多種參數。Hach HQd便攜式水質分析儀具有絕佳測量靈活性,電極更換等操作簡單,可自動識別電極。

HQd系列多參數水質檢測儀包含各種IntelliCALTM 電極,可測量pH、導電度、溶氧(LDO),LBOD,ORP 以及鈉、銨、氨、氟、硝酸鹽、氯等多項水質參數。

HQd meters connect with smart probes that automatically recognize the testing parameter, calibration history, and method settings to minimize errors and setup time. The advanced benchtop meter is designed to withstand years of continuous lab use. HQd meters feature a simple user interface that does not require manuals or training to operate.

The high-flowing reference and open junction of the pH Ultra electrode included in this package delivers fast stablilzation time even in the most difficult sample types and low ionic strength waters.

Designed for water quality experts, the Hach HQ440d benchtop meter is an advanced laboratory meter that takes the guesswork out of measurements. 
  • Flexible benchtop meter makes your lab testing of critical water quality parameters more efficient
    Two input channels for simultaneous measurement of pH, Conductivity, Dissolved Oxygen, BOD, ORP, Ammonia, Ammonium, Fluoride, Chloride, Sodium, and temperature - any IntelliCAL™ smart probe.
  • Intuitive user interface for simple operation and accurate results
    Guided calibration and check standard routines reduce calibration errors while stabilization alerts and visual measurement lock ensure that you can trust the accuracy of the results.
  • Trust your measurements - IntelliCAL™ smart probes store all calibrations in the probe
    Calibration history allows quick and easy change out of probes without re-calibrating. The HQd smart system records serial numbers, current calibration data, user ID, sample ID, time, and date automatically in the data log for complete GLP traceability.
  • Enhance productivity with an ultra-bright screen and large font size for easy to read results
    Internal USB ports simplify data transfer, peripherals, and software updates and connection to PCs, printer and keyboards.
  • Convenient kit includes everything you need to start testing
    Meter package includes HQ440d Benchtop Meter, PHC281 pH Ultra electrode with 1 m cable, ISEF121 fluoride electrode with 1 m cable, pH Buffer Kit (500 mL), pH storage solution (500 mL), fluoride standards, ionic strength adjustor powder pillows (qty 100), probe stand, 4 AA batteries, power adapter, USB cable for data transfer, quick-start guide, user manual, and documentation CD
