Product Description
KJ903P Portable pH/Dissolved Oxygen Meter
·Product description
Multiparameter portable pH/Dissolved Oxygen meter contains 3 measurement modes. The meter is used for measuring the pH, ORP and DO of the liquids.
·Features
pH Mode:
• Multiparameter portable pH/Dissolved Oxygen meter is equipped with a large backlit LCD.
• 1 to 5 points push-button calibration with auto-buffer recognition.
• Selectable pH buffer standard (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 millivolts measurement modes provide accurate ORP readings.
Dissolved Oxygen Mode:
• 1 or 2 points calibration using the 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 number of calibration points,
resolution, stability condition, measurement unit, etc.
• Reset feature automatically resumes all parameters back to factory default settings.
• 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.
• Multi-mode power scheme (battery, power adapter, computer's USB port) ensures that use
the meter smoothly.
