Hanna HI1230B Gel Filled PEI Body pH Electrode
The Hanna HI1230B Gel Filled PEI Body pH Electrode is a gel-filled combination pH electrode engineered for field and laboratory applications. It features a durable PEI body, double junction design, and a BNC connector for universal compatibility with most pH meters. This electrode offers low-maintenance operation, high reliability, and solid performance across a broad temperature and pH range, making it an excellent choice for environmental testing, educational labs, and routine industrial use.
Key Features
Rugged PEI Body
The electrode’s polyetherimide (PEI) housing offers strong mechanical resistance, making it ideal for use in the field and harsh laboratory environments.Low-Maintenance Gel Electrolyte
The gel-filled system eliminates the need for frequent refilling, allowing users to focus on testing without complex maintenance routines.Double Junction for Improved Stability
With a double junction reference system, the HI1230B resists contamination better than single junction electrodes—especially when working with challenging or dirty samples.Precision Spherical Tip
A 7.5 mm diameter spherical glass tip ensures consistent contact with the sample, enabling accurate and reproducible pH readings.Reliable BNC Connector
The standard BNC connection provides universal compatibility with a wide range of benchtop and portable pH meters.
