Extech Oyster Series pH-Conductivity-TDS-ORP-Salinity Meter

Exclusive, rugged design is ideal for use in the lab or in the field. The large, dual LCD is built into the adjustable “flip-up” cover. It is microprocessor-based with splash-proof housing and front panel tactile touch pad to slope and calibrate. Other features include a memory function that stores and recalls 25 labeled readings; an automatic temperature compensation for Conductivity/TDS via thermistor built into the conductivity cell; and a manual temperature compensation for pH (0 to 100°C). The complete kit includes a mini pH electrode, a thermistor probe, sample buffers, a polymer conductivity cell, 9V battery, neckstrap, and carrying case.
