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 Lab pH Tester has a refillable glass body and spherical glass sensing bulb made for everyday laboratory use.

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