LABMAN LMION40 ion meter is designed for high performance and easy
operation. The meter is capable of measuring up to 7 parameters,
including  ION concentration,pH, ORP Conductivity, TDS, Salinity, Resistivity, and temperature.

Features:

• Ion concentration mode directly displays readings in ppm, ppt, or any other units of your choice
• Calibrate up to 2 points for pH using USA or NIST buffer sets; Up to 5 points for ion concentration measurement
• Auto-buffer recognition eliminates calibration mistakes and ensures calibration accuracy
• Automatic temperature compensation for best accuracy under fluctuating temperatures
• Meters automatically calculate and display electrode slope
• Automatic message prompts help you easy to operate meter.
• Expanded memory stores and recalls up to 99 data sets
• USB Communication interface can be sent data to computer
• During the ion mode, 2 to 5 points push-button calibration from low to high concentrations
  Direct readout ion concentration simplifies the elaborate measurement process. 
  Automatic Temperature Compensation (ATC) ensures highly accurate measurements over the entire range.
