Apera Instruments Value Series EC20 Conductivity (EC) Pocket Tester Kit, ±1% F.S Accuracy in 0 to 20 mS/cm, BPB Sensor

Apera Instruments EC20 Pocket Conductivity Tester Kit is built for professional conductivity measurement of general water solutions, including tap water, drinking water, hydroponics, horticulture, aquaculture, pools& spas, education, environmental monitoring, etc.
Range: 0-20,000 µS/cm (20 mS/cm); Accuracy: 1% F. S; 1-2 points auto. calibration; 0 to 50˚C auto. temp. compensation.
The platinum black sensor adopts Apera's special processing technology, which minimizes electrode polarization, expands measuring range, and increases the firmness of the electrode, hence ensuring a significantly higher accuracy in a wide-range conductivity measurement than traditional stainless steel electrodes, and is easy to maintain.
The large LCD screen has Conductivity/temp. dual display and indications of completed calibrations and stable readings.
Practical functions to make your EC testing easier and more reliable: 2-point auto. calibration, 0 to 50˚C auto. temp. compensation. Self-diagnosis with out-of-range and low battery warning.
Complete kit: EC20 meter, 2 bottles of calibration solutions and a lanyard all in a portable carrying case. IP67 water-resistant. Up to 1000 hours of use powered by 4 AAA batteries. The product is CE and RoHS certified.
