Digital Pen-type Conductivity Meter LH-C502
• Economic type
• Electrode upgraded with temperature sensor
• Automatic Temperature Compensation
• Easy one point calibration
1. Introduction
When the original economic pen type conductivity meter was first introduced, conductivity and total dissolved solids measurements became easy and affordable. The LH-C502 is easy to use, in combination with its affordability made it the standard in EC and TDS measurement.
The electrode of LH-C502 is a combination of conductivity electrode and temperature sensor, make it possible to auto compensate the error caused by temperature changes during the measuring.
Without other dispensable functions, LH-C502 which known as an economic type but precise conductivity meter, used widely in our home market.

What is EC?
Electrical Conductivity (EC) is defined by the ability of a solution to conduct an electrical current.
What is TDS?
Total Dissolved Solids (TDS) is defined as the amount of solids dissolved in a solution.
How does an EC/TDS meter work?
Two electrodes with an applied AC voltage are placed in the solution. This creates a current dependent upon the conductive nature of the solution. The meter reads this current and displays in either conductivity (EC) or ppm (TDS).
How is TDS measured?
By means of a conductivity meter. The conductivity is measured and the TDS is calculated by a fixed mathematical formula in the meter.
What is the difference between microSiemens and milliSiemens?
Both are units of conductivity. 1000 microSiemens (µS) = 1 milliSiemen (mS).
If I have a TDS meter with a 0.5 conversion factor how do I convert to the correct 0.7 value?
Multiply by 1.4; ex: 500 x 1.4 = 700.
