of the most popular pH meters on the market, the portable micorprocessor-based HI 8424 is able to perform pH, ORP and temperature measurements with a high degree of accuracy and fast response.  It features an enhanced user interface, rainproof casing, battery percentage indication, low battery detection, automatic shut-off, automatic calibration, and error codes to guide the user in calibration and troubleshooting.\u003c\/span\u003e\u003cspan style=\"font-family:\" times new roman small font-size:=\"\"\u003eThe instrument has automatic calibration at one- or two-points with three memorized buffer values (pH 4.01, pH 7.01, and pH 10.01).  Once the instrument has been calibrated, the buffer values used during calibration are displayed with tags on the LCD.  This feature keeps users informed of the current calibration and helps to avoid taking measurements that are out of range.\u003c\/span\u003e\u003cspan style=\"font-family:\" times new roman small font-size:=\"\"\u003eThe user
