Go Direct® Flat pH BNC Electrode

Connect the Flat pH BNC Electrode to our Go Direct® Electrode Amplifier to measure pH of solutions containing proteins or sulfides.

Description

The glass membrane is flat instead of a bulb, making it more durable, easier to clean, and allows for flat surface measurements or smaller sample sizes. It features a sealed, gel-filled, double-junction electrode, making it compatible with Tris buffers and solutions containing proteins or sulfides. The flat glass shape also makes it useful for measuring the pH of semisolids such as food or soil slurries.

Specifications

  • Range: pH 0–14 (Some sodium error in ranges greater than pH 12 due to thicker glass and higher impedance values)
  • Electrode type: Double-junction, sealed, gel-filled, Ag/AgCl reference, polycarbonate body
  • Membrane style: Flat glass
  • Storage solution: pH 4/KCl solution (10 g KCl in 100 mL buffer pH-4 solution)
  • BNC connector
  • Temperature range:

    • 0– 100ºC (readings not compensated)
    • 12 mm OD
    • Impedance: ~20 kΩ at 25ºC
  • Response time: 98% of full response in 30 s at 25ºC

Requirements

The Go Direct Flat pH BNC Electrode connects via BNC to our Go Direct Electrode Amplifier.
