POPUPTITLE ×

Each All-in-One Acorn electrode features a built-in temperature sensor for taking readings with Automatic Temperature Compensation (ATC). Choose a single junction electrode for field, clean water, and general purpose applications. Choose a double junction electrode for most applications, including dirty water, heavy metals and organics applications. Each electrode is 12 mm dia with a 3 ft cable.

Gel-Filled vs Refillable 
Gel-Filled are convenient and easier to maintain than refillable (liquid) electrodes. However liquid filled will provide a faster response. Users can also adjust the fill solution to optimize performance.

Glass vs Epoxy Body Electrodes
Glass body electrodes on average will be able to withstand higher temperatures (100 C as to 80C for epoxy)  The glass design offers better sealing, fusing glass to glass instead of relying on adhesives. the epoxy however is less susceptible to break.
