Model pH 211 measures pH range of 0-14 ±0.01 and temperature range of 0-100°C ±0.5ºC. In conjunction with ISE and ORP electrodes, microprocessor-based meter can also measure mV from ±399.9 to ±1,999 mV. Automatic buffer recognition lets user select 1- or 2-point calibration. Display shows pH or mV and temperature simultaneously along with step-by-step operation.
