Product information "HI4522 RESEARCH GRADE ISE/pH/ORP/°C - EC/TDS/Salinity - 2 Channel USP"
HI 4522 is a research grade, benchtop instrument that feature 8 measurement ranges: pH, ORP (Oxidation Reduction Potential), ISE, conductivity, resistivity, TDS, salinity and temperature. This instrument incorporates dual channels with a separate temperature input and support the external reference electrodes required by half cell pH and ISE sensors.
The user interface is customizable and capable of displaying two channels at the same time, showing the measurements in various modes: basic measurement with or without GLP information, graph or logging data.
This instrument offers multi-language support and contextual help is available through a dedicated Help key. Clear tutorial messages and directions are available on-screen to quickly and easily guide users through all measurement and calibration procedures to ensure measurements and calibrations are performed properly.
HANNA’s pH Calibration Check™ diagnostics system ensures accurate readings every time by alerting users of potential problems during the calibration process. The Calibration Check™ system eliminates erroneous readings due to dirty or faulty pH electrodes or contaminated pH buffer solutions. After the guided calibration process, electrode condition is evaluated and an indicator is displayed informing the user of the overall pH?electrode status.
Automatic, semiautomatic and manual pH calibration is available in up to five points, with eight standard (1.68, 3.00, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45) and up to five custom buffers. The Out of Calibration Range and Cal Due features alert the user in the event the measurement is far from the calibration point or when the meter is due for recalibration. Proper, scheduled calibrations are crucial for accurate and repeatable measurements.
HI 4522 features up to five point Manual Selection and Custom Standard ISE calibration with up to five standard solutions and up to five custom solutions with or without temperature compensation. From the on-screen list, users can select their ISE electrode parameter along with it’s standard configuration profile or create their own.
Up to a four point automatic or custom standard conductivity calibration can be performed in up to four points as well as probe cell constant. One fixed point salinity calibration can be performed on the Percent Scale only. Three salinity ranges are available: practical scale, natural sea water scale and percentage scale.
Up to ten profiles can be saved and recalled eliminating the need to reconfigure each time when a different probe is used. User definable configurations can include: temperature compensation in accordance with each parameter, isopotential points for pH and ISE, measurement units of ISE concentrations and ISE electrode type, temperature units, EC temperature reference, EC temperature coefficient, EC probe type, and cell constant.
Three selectable logging modes are available: Automatic, Manual and AutoHold logging. Up to 100 logging lots with up to 10,000 recods each can be stored for automatic or manual modes along with up to 200 USP reports, and up to 100 ISE methods reports. Automatic logging features a selectable area and sampling period while GLP information includes complete data about user calibration of each parameter and identification information for the instrument, user, and company. Data can be transferred to a PC via the opto-isolated RS232 or USB ports and HI 92000 software (optional).
