The 826 pH mobile is a handy and very easy-to-use pH meter with a wireless infrared interface for data transfer to a printer or PC. Numerous functions, e.g. input possibilities for user or sample identification, 3-point calibration with automatic buffer recognition and various monitoring functions allow GLP-compliant working in virtually any location. The memory function can store up to 200 measured values with date, time and sample identification; these can be called up or transmitted to a printer or PC at any time. If the 6.0228.020 Primatrode is used then the 826 pH mobile meets the requirements of protection code IP 67, i.e. even brief immersion in water will not harm the instrument. Power supply is from four LR6, UM3 or AA batteries; in normal operation up to approx. 750 working hours are possible.
