pH made easy    Besides the simultaneous display of measurement value and temperature, the big, well organized display provides other helpful information. Icons immediately inform you about the condition of the electrode and whether a measurement is in progress or whether the reading is already stable. The clearly labeled keypad makes operating the meter child's play.        Robust electrodes    The low-maintenance LE407 pH plastic electrode and 4 buffer sachets are included in the kit version. An LE510-ORP plastic electrode can be connected for ORP measurements. The robust splash-proof (IP54) system is perfectly suited for experiments in the field and in training courses.        Useful accessories    A quick guide, laminated for those occasional spills, an electrode clip and a wrist strap are included as standard. The field kit version also comes with a handy carry bag with 4 sample bottles. Needless to say, calibration solutions, cleaning solutions and separate temperature sensors are also available.
