HQ30d single input digital multi-parameter analyzer is a plug and play and can be applied to any one IntelliCAL electrode analyzer. An analyzer can measure pH, conductivity and LDO; electrode serial number can be automatically registered in the analyzer; operator ID and the sample ID can be linked to the measured and stored in the recorder can be used to ultimately traceable; Replace measuring parameters / electrode fast, easy, without recalibration; IntelliCAL electrode factory calibration can be used directly; password protection feature ensures accurate data, no reports of tampering; 500 data logging function can store the measurement results, calibration and inspection standards. Technical parameters: Power: 4AA batteries Battery life:> 200 hours, including AC / DC power connector single parameter display: can display readings from an electrode. pH electrode: pH, mV, temperature conductivity cell: The selected parameters, temperature correction and temperature LDO electrode: dissolved oxygen, pressure, temperature data memory: 500 groups of data storage: calibration data are stored in the log. In the "push-to-read" mode and interval measurement mode can be automatically stored. In the "continuous reading" mode manually store. Data record: the user selects the interval temperature correction / compensation: automatic locking display: continuous measurement mode or press the measurement mode that reads an average LDO readings function. Automatic pH buffer recognition: There are three options available: pH automatic recognition: recognizes the pH standard solution of IUPAC 4,7,10: 1.679,4.005,7.000,10.012 DIN: 1.09,4.65,9.23 Waterproof: Determination instrument housing can soak for 30 minutes in one meter of water (IP67) Ordering Information: Ordering Information: HQ30d53000000 HQ30d single input digital multi-parameter analyzer host HQ30d5330100 HQ30d host, standard LDO dissolved oxygen probe, 1m cable HQ30d5330300 HQ30d host, standard Type LDO dissolved oxygen probe, 3m cable 8505100 HQ30d host, the impact resistance of LDO dissolved oxygen probe, 5m cable HQ30d53101000 HQ30d host, pHC10101 standard pH electrode, 1m cable HQ30d53103000 HQ30d host, pHC10103 standard pH electrode, 3m cable HQ30d53115000 HQ30d host, pHC10105 impact type pH electrode, 5m cable HQ30d53201000 HQ30d host, CDC40101 standard type conductivity electrode, 1m cable HQ30d53203000 HQ30d host, CDC40103 standard conductivity probe, 3m cable HQ30d53215000 HQ30d host, CDC40105 impact type conductivity electrode, 5m cable HQ30d53101201 HQ30d host, PHC10103 standard pH electrode (1 m cable), CDC40103 standard conductivity probe (1 m cable) HQ30d53103203 HQ30d host, PHC10103 standard pH electrode (3 m cable), CDC40103 standard type conductivity electrode (3 m cable ) HQ30d53101301 HQ30d host, PHC10103 standard pH electrode (1 m cable), LDO10101 standard oxygen electrode (1 m cable) HQ30d53103303 HQ30d host, PHC10103 standard pH electrode (3 m cable), LDO10103 standard type conductivity electrode (3 m cable) HQ30d53201301 HQ30d host, CDC40101 standard conductivity probe (1 m cable), LDO10101 standard oxygen electrode (1 m cable) HQ30d53203303 HQ30d host, CDC40103 standard type conductivity electrode (3 m cable), LDO10103 standard conductivity of the electrode (3 m cable) 8506300 HQ30d base type oxygen kits, including HQ30d host, LDO10101 dissolved oxygen sensor, pedestal 5,825,800 carrying case: can accommodate two impact sensors, a HQ30d or HQ40d Lord, 5 120 beaker 5189900 low ion concentration hash intelliCAL 8,506,600 flow cell probe holder (LBOD electrode except)
