SL321-NH4 Handheld Ammonium Ion Meter,NH4 Ion Meter,Datalogger,USB function

SL321-NH4 Handheld Ammonium Ion Meter,NH4 Ion Meter,Datalogger,USB function   Description: Portable ammonium ion meter, 5 points calibration, selectable concentration units. The meter is suitable for measuring the ammonium ion concentration of samples. Accuracy: 0.5% full scale.   Features:
• High accuracy portable 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, including the ppm, mg/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 concentration units, stability
conditions, resolutions, hold function, 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.
• Multi-mode power scheme (battery, power adapter, computer's USB port) ensures that use
the meter smoothly.   Specification:
