HQ30d single-input multi-parameter digital analyzer is a plug-and-play analyzer suitable for any IntelliCAL electrode. An analyzer can measure pH, conductivity and LDO; The electrode serial number can be automatically registered in the analyzer. Both the sample ID and the operator ID can be linked to the measurement and stored in the recorder for final traceability. The replacement of measurement parameters/electrodes is fast and convenient without recalibration. The factory calibrated IntelliCAL electrode can be used directly. The password protection function of data can ensure accurate and tamper-free reports; A 500 data logging function stores measurement results, calibrations and inspection standards.

technical parameters:

power supply: 4AA batteries; battery life:>200 hours, with AC/DC power connection
Single parameter display: can display readings from 1 electrode.
pH electrode: pH,mV, temperature
Conductivity electrode: selected parameters, temperature correction and temperature
LDO electrode: dissolved oxygen, pressure, temperature
Data Memory: 500 sets of data
Data storage: The calibration data is stored in a log. Automatic storage in "press-and-read" mode and interval measurement mode. In the "Lian
Manual storage is required for continuous reading mode.
Temperature correction/compensation: automatic Data logging: user selection interval
Lock display function: continuous measurement mode or press-and-read measurement mode has the function of averaging LDO measurement readings.
Automatic identification of pH buffers: Three options are available:
pH automatic identification function: can identify the pH of 4,7,10 standard solution
IUPAC: 1.679,4.005,7.000,10.012
DIN: 1.09,4.65,9.23
Water resistance: the tester shell can be soaked in water at a depth of 1 meter for 30 minutes (IP67)
