High Accuracy Water Analysis Instrument Nitrate Ion Meter Tester
Brief introduction of ion meter
The ion meter is an electrochemical analyzer used to measure the ion concentration in a solution. Measurement of H + also belongs to the ion meter, we generally call its PH meter or acidity meter, the general people refer to the ion meter is measured in addition to H + other than the electrochemical electrochemical instruments.
Features of NANBEI ion meter:
• High performance portable nitrate ion meter is equipped with a large LCD display.
• 2 to 5 points calibration from low to high concentrations.
• Direct ion concentration readout simplifies the elaborate measurement process.
• Selectable multiple concentration units include the ppm, mg/L, mmol/L and mol/L.
• 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 reading for easy viewing and recording.
• Manual temperature calibration improves the measurement accuracy of meter.
• Selectable temperature unit (°C or °F) meets different application requirements.
• mV measurement mode allows user to check performance of the ion selective electrode.
• Automatic electrode diagnosis shows the slope of sensor.
• Help message as a operational guide that helps you quickly begin using the meter.
• System menu can be used to set 8 parameters, including the number of calibration points,
stability condition, hold function, 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.
