Product details
- Detailed Introduction
Hash Company'sHQdThe series of portable water quality analyzers can currently detect11 Various parameters, including standard type, sturdy type, andUltraChoose from multiple electrode options. hashHQdPortable water quality analyzers have great measurement flexibility, simple electrode replacement and other operations, and can automatically identify electrodes. This set of multi parameter water quality testing equipment includes variousIntelliCALTMElectrode, measurablepHConductivity, dissolved oxygen（LDO），LBOD，ORPAnd parameters such as sodium, ammonium, ammonia, fluorine, nitrate, chlorine, etc.
-Instrument features and advantages:
● One machine with multiple uses
One unitHQDThe multi parameter water quality detector can be connected to different electrodes for measurementpH. ORPParameters such as sodium, ammonium, ammonia, fluoride, nitrate, chlorine, conductivity, dissolved oxygen, etc.
● Multiple measurement methods
HQDThe portable water quality analyzer provides three reading modes, which can achieve measurement of instant reading, indirect reading, and continuous reading.
● Humanized correction guide
HQdThe operation interface of the 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 the correct calibration results can be obtained.
● Complete data traceability
HQdThe series multi parameter water quality detector can automatically record the serial number of the electrode, current calibration data, and user informationIDSampleIDThe time and date are all saved in the system's data log. Each measurement data can be compared with the sampleID, userIDThe association of electrode serial numbers and other data ensures complete data traceability and report supervision.
●USBData transmission method
HQDPortable water quality analyzer providedUSBInterface, can easily transfer data results toUIn disks and computers.
● Fully intelligent software system
The upgraded software allows users to customizepHStandard solution, which can support users to choose according to their own preferencespHStandard solution calibrationpHAnd not limited to just a few fixed onespHStandard solution. For conductivity, users can freely choose the reference temperature for temperature compensation, not limited to a fixed temperature. When both conductivity electrodes are equipped for dissolved oxygen,HQDThe portable water quality analyzer can automatically calibrate the dissolved oxygen salinity based on the measured salinity, without the need for manual input.
● Shared laboratory and on-site use
HQDAll connections between portable water quality analyzers and electrodes are safe and waterproof. It can be used for both laboratory analysis and on-site analysis.HQDAll connections between the portable water quality analyzer and the 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 extremely convenient.
● Large screen, multi parameter, multi item display.
