Apera TDS20 Pocket TDS MeterThe Apera Instruments TDS20 tester is a reliable pocket TDS tester with the best value for all kinds of regular TDS testing, including tap water testing, agriculture, aquaculture, pools and spas, education, etc. (Range: 0-100.0 ppm, 0-1000 ppm, 0-10.0, Accuracy: ±1% F.S).
1-2 points auto calibration with auto buffer recognition, 0 to 50C auto temp. compensation.
The BPB (Brush-Resistant Platinum Black) sensor adopts our special processing technology, which minimizes electrode polarization, expands measuring range and increases firmness of the electrode, hence ensuring a much higher accuracy and consistency in a wide-range EC measurement than traditional stainless steel electrodes and is easy to clean.
The unique platinum black conductivity probe technology ensures wide range measurement with accuracy and consistency.
Features
