Pocket-Type Waterproof pH Meters - pHep 5 Waterproof pH Pocket Meter (0.01 pH) - HI98128

Hanna Instruments - HI 98127 and HI 98128 are waterproof pH and temperature meters. The housing has been completely sealed against humidity and designed to float. All pH readings are automatically temperature compensated (ATC), and temperature values can be displayed in °C or °F units. The meters can be calibrated at one or two points with auto-buffer recognition and against five memorized buffer values. Measurements are highly accurate with a unique stability indicator right on the LCD. These meters are also provided with battery level indication at start-up, and with a low battery symbol which warns the user when the batteries need to be replaced. In addition the Battery Error Prevention System (BEPS) avoids erroneous reading caused by low voltage level by turning the meter off. The HI 73127 pH electrode, supplied with the meters, is interchangeable and can be easily replaced. The stainless steel encapsulated temperature sensor facilitates faster and more accurate temperature measurement and compensation. HI 98127 and HI 98128 are warranted for one year against defects in workmanship and materials when used for their intended purpose and maintained according to instructions.
