HQ40d Dual Input Multi Parameter Digital Analyzer

Instrument Introduction:
The HQ40d dual input multi parameter digital analyzer is a plug and play, dual interface display analyzer that can be used with any two IntelliCAL electrodes. An analyzer can measure pH, conductivity, and LDO, and can use two different electrodes to measure simultaneously. The measurement information of both electrodes can be seen on the same display screen, and GLP/ISO data can be transmitted to a USB flash drive or computer - all data records can be transmitted, or individual readings can be transmitted. In addition, HQ40d also has advantages such as saving time and measuring economy.

Technical Indicators:
Please refer to the technical parameters of the electrode for the measurement range
Power supply: 4AA battery; Battery life:>200 hours, including AC/DC power connection
Display: can display readings from 1 or 2 electrodes, and can display readings from both electrodes simultaneously
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: Calibration data is stored in logs. It can be automatically stored in the "press to read" mode and interval measurement mode. Manual storage is required in the 'continuous reading' mode.
Data transfer: Data can be downloaded to a computer or flash memory using a USB interface. It can automatically transmit data records and also transmit measured readings.
Temperature correction/compensation: three modes, namely off, automatic, and manual (correction should be based on parameters)
Lock display function: Continuous measurement mode or press to read measurement mode has the function of averaging LDO measurement readings.
Automatic recognition of pH buffer: There are three options to choose from:
PH automatic recognition function: can recognize standard solutions with pH values of 4, 7, and 10
IUPAC: 1,679, 4,005, 7,000, 10,012,
DIN： 1.09，4.65，9.23
Waterproof: The measuring instrument casing can be soaked in water up to 1 meter deep for 30 minutes (IP67)
