Name: KL-139C TDS Tester
Product description::
It is a budget priced pocket size total dissolved solids (TDS),  
tester .   
Automatic temperature compensation ensures correct 
readings.  
The  digital display allows the operator to see the 
readings from every angle.    
Calibration is very simple to perform: immerse the tester 
in the calibration  solution and adjust the trimmer on the 
rear of the meter until the correct  value is displayed.   
For a number of applications, it is crucial to determine 
the quantity of dissolved salts in a body of water. High 
concentrations can cause corrosion and deposits in 
heating systems and can be detrimental to aquatic 
plants and animals.
