Energy-Saving and Smart Shutdown
Protect battery life and data integrity with built-in safeguards. An auto-off function powers the meter down when idle. A blinking indicator warns when battery power drops below 10%. The unit will shut off entirely if battery voltage could compromise reading accuracy.
50-Reading Data Log
Track your testing history automatically. The HI97733 stores the last 50 measurements, which can be instantly recalled via the Log Recall Menu for trend analysis and record-keeping.
CAL Check™ Accuracy Validation
Keep your photometer in spec with CAL Check™ technology. Insert certified calibration standards and follow the onscreen prompts to verify instrument performance. If needed, simply recalibrate to restore accuracy.
