Pen-type conductivity tester

Pen-type conductivity tester NPT-CD506 TDS pen tester in drinking water
Features:
★  Measuring range: conductivity:0~200uS/cm(k=0.1),0~2000uS/cm(k=1),0~20mS/cm（k=10）,TDS:0～100ppm（k=0.1）,0～1000ppm（k=1）  .
★  Temperature:0～60℃,LED segment code LCD display(TDS/conductivity value and temperature value).
★  Numerical calibration and temperature calibration function.
★  Using 32-bit high-performance processor, high stability and low power consumption.
★  Automatically identify the standard solution, the standard solution does not match and the calibration cannot be completed.
★  The TDS/conductivity mode can be switched freely, when the electrode constant is the same, there is no need to replace the electrode after switching the mode.
★  Automatic shutdown after five minutes without key operation.
★  Low battery reminder function.
★  Long standby technology, theoretical standby time is more than one year.
★  Protection grade: IP65.
