HORIBA combination pH electrodes with the pH glass and reference half-cell in one body, but no built-in temperature sensor. They connect to a single pH input and are the right choice when your meter has a separate temperature probe, or when the sample is held at a known constant temperature.

Important: because there is no temperature element, these electrodes cannot drive automatic temperature compensation on their own. If your samples vary in temperature and you need compensated readings, either pair one of these with a separate temperature electrode such as the 4163-10T, or choose a 3-in-1 electrode instead.

General purpose

• 9415-10C (3200611623) — glass-bodied lead-free dome electrode. The dome tip is robust and easy to rinse.
• 9425-10C (3200611625) — plastic-bodied lead-free electrode with 1 m cable. The most economical option here and far less fragile than glass.

ToupH durable glass

• 9418-10C (3200611627) — micro ToupH glass electrode for small volumes and narrow vessels.
• 9480-10C (3200611628) — long ToupH lead-free electrode for deep flasks, tanks and reactors.
• 9481-10C (3200611631) — ToupH lead-free sleeve electrode. The sleeve junction can be opened and flushed, so it handles slurries, emulsions, proteins and soil extracts that would clog a ceramic junction.

Special geometries

• 6069N-10C (3200995147) — micro tube glass electrode, for very small samples and tube-based work such as NMR tubes and microcentrifuge tubes.
• 6261-10C (3014081807) — flat-type glass electrode. The flat sensing surface sits on a sample rather than needing immersion, making it the electrode for surface pH, skin, paper, leather, gels, agar plates and drops.

Applications

• Laboratory pH measurement where temperature is separately monitored or controlled
• Food, beverage and dairy quality control
• Cosmetics, personal care and dermatological surface pH testing
• Paper, textile and leather surface pH checks
• Microbiology and culture media testing
• Small-volume and micro-sample work
• Environmental water and soil extract analysis
