HI520 is an advanced process controller that can be configured for applications requiring monitoring and/or control of four main water-analysis parameters: pH, ORP, Conductivity, and Dissolved Oxygen.

• Waterproof IP65 (Nema 4X) enclosure
• Multi-color LED status indicators & audible alarm
• Universal mounting kits available with wall, pipe, and panel mounting options (All mounting kits must be ordered separately.)

Wastewater treatment plants rely on bacteria to break down the organic compounds found in water. If the amount of dissolved oxygen in the wastewater is too low, these bacteria will die and septic conditions will occur. The amount of DO must be consistently monitored to ensure proper waste treatment.

Our HALO2 Wireless Field pH Tester has a durable PEI body and spherical sensing bulb, perfect for use in the field.

• Open-source Bluetooth allows easy integration into current data logging systems
• IP65 water resistant protection
• Equipped with everything you need for successful testing right out of the box
