3 in 1 Portable pH/ORP/Temp Meter

PH-013 is a portable pH meter designed to be rugged   and easy-to-use, yet be reliable and practical.    
It is ideal for education and for measurements in the field.    
Simple pH calibration is performed manually through 2 trimmers.    
Measurements are automatically compensated for variations  in temperature.    
It shows the reading together with the current mode  (pH, mV or °C).
