Product Description
HI-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
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
- HI-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
