The i-Steward ensures repeatable and consistent measurement accuracy for optimal peace of mind. The large LCD display and touch keypad makes changing the parameters, executing setup, and performing calibration as simple as using a smartphone.

Features

• Multi-Parameter Measurement: Accurately measures pH, Oxidation-Reduction Potential (ORP/mV), and Temperature in benchtop laboratory settings.
• pH Measurement Range & Accuracy: Wide pH measurement range from -2.00 to 16.00 pH with an accuracy of ±0.01 pH.
• Selectable pH Resolution: Configurable resolution between 0.1 pH and 0.01 pH depending on testing requirements.
• ORP / mV Measurement: Measures redox potential from -2000.0 mV to +2000.0 mV with ±1 mV accuracy and 1 mV resolution.
• Temperature Compensation: Features Automatic Temperature Compensation (ATC) and Manual Temperature Compensation (MTC) from -5.0 °C to 110.0 °C (23.0 °F to 230.0 °F) with ±0.5 °C accuracy.
• Up to 3-Point Calibration: Supports up to 3-point pH calibration to ensure high measurement linearity across broad pH spectrums.
• Automatic Buffer Recognition: Equipped with pre-programmed buffer groups for fast and error-free calibration.
• i-Steward Electrode Diagnostics: Intelligent monitoring system that continuously tracks electrode health ("Electrode Dirty/Broken") and displays calibration slope and offset indicators.
• Calibration Due Alarm: Built-in reminder function alerting users when a scheduled recalibration is required.
• 1,000-Set Internal Memory: High datalogging capacity storing up to 1,000 measurement data sets with date and time stamps for GLP/GMP compliance.
