Bante903
Benchtop pH/ORP/DO Meter
pH Mode:
• High accuracy benchtop multiparameter water quality meter is equipped with a large backlit LCD display.
• 1 to 5 points push-button calibration with auto-buffer recognition.
• Selectable pH buffer standards (USA/NIST/DIN) or using the custom calibration solutions.
• Automatic electrode slope display helps user decide whether to replace sensor.
ORP Mode:
• Single point offset calibration allows adjusting the displayed value to a known standard.
• Relative and absolute millivolt measurement modes provide accurate ORP readings.
Dissolved Oxygen Mode:
• 1 or 2 points calibration using air-saturated water and zero oxygen solution.
• Manual salinity and barometric pressure compensation improve the measurement accuracy.
Other Features:
• Automatic Temperature Compensation provides accurate reading over the entire range.
• Calibration Due Reminder prompts user to calibrate the meter regularly.
• Stability indicator automatically shows current measurement status.
• Auto-Hold function freezes stable measured value for easy viewing and recording.
• Manual temperature calibration corrects temperature deviation.
• Selectable temperature unit (°C or °F) meets different application requirements.
• Automatic electrode diagnosis shows zero point offset and slope of the electrode.
• Help message as a operational guide that helps you quickly begin using the meter.
• System menu allows setting the 11 parameters, including the calibration points, resolutions, stability conditions, measurement units, etc.
• Reset feature automatically resumes all parameters back to factory default options.
• Expanded memory stores and recalls up to 500 readings.
• Built-in real-time clock stamps stored data to meet GLP standard.
• Stored data can be transferred into computer by USB communication interface.
