Series 3W probes, consisting of metallic bars within a protective plastic shield, are designed to be suspended in liquid with PVC-insulated wires. They are ideal for applications where rigid electrode rods are impractical or cumbersome, such as:

• Deep Wells

• Pump Control

• Waste Water

• Deep Tanks

3Z1A wire and the 3Z1B adaptor kit are required for use with 3E, 3F and 3N fittings.
