Hanna HI 1131B Glass pH Electrode with BNC Connector
Featuring a cleanable glass body, it provides fast and precise measurement results.
The HI 1131B electrode comes with a BNC connector, allowing easy connection to many pH meter devices.
Ideal for general laboratory use.
The glass type, bulb shape, body material, connection type, reference type, and electrolyte used are among the key design aspects affecting performance.
The HI1131B pH electrode uses a high-temperature (HT) glass, spherical bulb, glass body, single ceramic frit, double junction, and is refillable with 3.5M KCl solution.
High Temperature Glass Formulation: Measuring pH at very high temperatures can damage standard glass probes and shorten electrode life. The high-temperature glass withstands such conditions, providing longer probe lifespan.
Spherical Glass Tip: The spherical tip design offers a larger contact area with the sample, resulting in faster measurement response.
The electrode has a 1-meter cable length.
Refillable: The HI1131B is a refillable probe. As a double junction pH electrode, its filling solution is HI7082 3.5M KCl. This solution does not contain silver, unlike single junction electrodes. The absence of silver prevents silver deposits forming on the junction surface that could block it, which would otherwise cause drifting and unstable readings.
