Hanna Instruments-5521-02 Research Grade pH/ORP/EC/TDS/Resistivity/Salinity Bench Meter
Hanna Instruments-5521 is an ideal research-grade instrument with large, easy read graphic display and soft touch keypad.
Up to four conductivity calibration points can be used to increase measurement accuracy:
- One fixed-point salinity calibration on the percent scale
- Three methods for calculating seawater
- Practical scale
- Natural seawater scale
- Percent scale
Customise to your application
The display is customisable and can display two channels simultaneously. Measurements are given in various modes: basic measurement, with or without GLP information, graph or logging data. Display colours are also selectable.
Up to 10 profiles (5 for each channel) can be saved and recalled for both meters eliminating the need to reconfigure each time a different electrode is used. User definable configurations include:
- Temperature compensation modes
- Temperature units
- Isopotential points for pH
Key features
Precision analysis
- EC specific applications: USP <645> method; salinity in seawater; TDS
- Five point pH calibration
- Multiple input channels: pH/ORP and EC/TDS/Resistivity/Salinity
pH CalCheck
- CalCheck for pH alerts users of calibration status and eliminates erroneous readings due to dirty or faulty pH electrodes or contaminated buffer solutions
- After calibration, electrode condition is evaluated and overall status of pH electrode is indicated
- To avoid taking readings with old calibrations, the instrument automatically reminds the user when calibration has expired
EC USP Mode
- Hanna Instruments-5521 can use EC probes for conductivity measurements required to prepare water for injection (WFI) according to USP <645>
- On-screen instructions explain how to perform each stage and automatically check temperature, conductivity and stability are within USP limits
- Comprehensive results displayed on a single screen at end of the test
- Save up to 200 reports for future recall
User friendly
- Large log memory with different logging methods
- Multi language support and contextual help through dedicated HELP key
- Clear tutorial messaging on-screen - available from any mode
- Capacitive touch keypad
- New and improved backlit display
