WD-35434-90 Multi-probe flowblock for use with Oakton 650-series meters by Oakton

The Oakton multi-probe flowblock can be used directly in-line with most ground water pump systems. The flowblock is designed for minimal sample volume (less than 40 mL with probes installed) to virtually eliminate the need to stir the sample. Solid acrylic block stands up to field conditions. Compression fittings around probes provide a leak-proof setup. Includes 3/16" and 1/4" quick-connect barb fittings.

• Measure several parameters from the same sample source at the same time
• Sensors are positioned directly in the sample stream
• Designed to work with one Oakton conductivity probe, up to two standard 12-mm diameter pH, ORP, or ion-selective electrodes (one plug included), and one Oakton dissolved oxygen probe
• Compatible with flow rates from 100 mL/min up to 1 gal/min
• Includes quick-connect barb fittings for easy tubing connection and cleaning
