There are only 2 buttons with which you can select from a range of calibration buffers and even the temperature scale most familiar to you. The housing is waterproof and rated for IP67 conditions. The multi-functional probe includes pH, EC/TDS and temperature in one convenient, rugged handle. Other selectable features include different TDS factors, a range of temperature coefficients and standardized buffer recognition values. To ensure against interference from transient electrical noise, a solid state amplifier is integrated into the probe. Complete with instruction manual and hard carrying case.
