PH Meter Martini pH 55, milwaukee ph meter ph 55, pH Meter Air, martini ph55 waterproof ph meter

PH Meter Martini pH 55 , milwaukee ph meter ph 55 IP67 Waterproof pH tester with Large dual-level LCD that displays pH and temperature ( ° C or ° F) . The large display shows readings in an extended range from -2.0 to 16.0 pH and simultaneously shows temperature from -5.0 to 105.0° C or 23.0 to 221.0° F. pH55 has a stability indicator and hold function that freezes the display for easy and accurate recording. The large display also has graphic symbols to guide you through all operations. Complete with a temperature probe for faster and more precise temperature measurement it compensates automatically for temperature. Calibration is made automatically in 1 or 2 points with memorized standard and NIST buffer sets. Auto power OFF saves battery power after non-use. The double-junction electrode can be replaced in a very fast and simple way! The modular design allows easy electrode and battery replacement.
