Pocket electrical conductivity tester NPT-CD501 tap water TDS pen tester
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.
