As high performance lab meter in your hand The SC-110 portable meter features microprocessor design with IP65 waterproof protection. The meter is compatible with 4-electrode cell which allows a wide range of application from medium to high conductivity solutions and also for salinity & TDS. When combines with resistivity cell, it measures very low to medium conductivity water such as pure water with high accuracy. The advanced data logger function allows the meter automatically measure and save with time interval up to 450 sets, and it can direct transmit the data through RS-232 interface to a computer or a printer. Hence, it not only can be as field measuring but also as field recording without hand writing or manually pressing the save button.
