• Portable conductivity and TDS meter
• Automatic range selection for optimum resolution
• Automatic or manual calibration
• Storage of up to 32 readings
• 500 hours battery life
The 470 hand held conductivity/TDS meter allows calibration by direct cell constant entry or through the use of standard solutions. The display simultaneously shows temperature compensated conductivity or TDS and temperature. For optimum resolution the best conductivity/TDS range is automatically selected, whilst temperature compensation is achieved using an adjustable temperature coefficient.
