This modern looking meter is only 0.7 in thick and extremely ergonomic, fitting comfortably in your hand. The HI98318 has a very large easy to read LCD display that shows both EC or TDS and temperature along with calibration, stability and low battery indicators. All operations are simplified to two buttons. One is for turning the meter on\/off and the other for automatic one point calibration.\u003c\/p\u003e\n\u003cdiv class=\"break\"\u003e\n\u003cul\u003e\n\u003cli\u003eGraphite sensor for reduced polarization effect\u003c\/li\u003e\n\u003cli\u003eTwo-button operation\u003c\/li\u003e\n\u003cli\u003eQuick Calibration Mode using Hanna Quick Cal pH\/EC Calibration Solution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"break\"\u003eThe GroLine Waterproof EC\/TDS Tester is made specifically for hydroponics, provides a simple, inexpensive solution to measure fertilizer concentration in a nutrient solution.
