Oakton Multi-Electrode Flow Through Block WD-35434-90

Multi-probe flow-through block can be used directly in-line with most ground water pumping systems, allowing you to measure several parameters of a sample at the same time. Operates at minimum flow rates of 100 mL/min to 1 GPM. Sensors sit in direct line of the sample stream and keep void volume at less than 40 mL, reducing stirring dependence of sensors. This acrylic flow-through block accepts up to 4 probe types - 2 pH, ORP or ISE electrodes 12mm diameter, 1 Conductivity/TDS electrode 14 mm diameter, and 1 DO electrode 25mm diameter. Flow-through block is compatible with most makes and models of water quality instruments.
