Professional 0.6" LCD Pen-type EC Conductivity Meter - Yellow + Black

Pros: - Pretty cheap - Works for measuring nutrient levels in hydroponics - Can't be much simpler to use .. turn the switch, dip in water, look at the number on screen

Cons: - Not very accurate, seems to report results in µS/cm with a multiplier of 100, e.g. when screen says "08" it means 800µS/cm - Hard to calibrate if you need that, since the accuracy is so poor

Other: - Cheap and working EC meter, measurements reported in µS/cm with a stepping of 100 µS/cm

Pros: The most important pro of this product is the price, easy for manipulation and more easy is the calibration. It comes calibrated from factory, and gives a lecture quick and with precission. Works for measuring nutrient levels in hydroponics

Cons: The LCD is very small, it have a poor design, the color Yellow and the size is too big

Other: Cheap price, light weight and a good inversion to control water EC, measurements reported in µS/cm with a stepping of 100 µS/cm Technical Specification: Model KL-1371 Measuring range 0~19.9EC 0~19.99EC Resolution 0.1 EC 0.01 EC Accuracy 2?F?
