Hanna HI12301 Digital PEI Body pH Electrode
The Hanna HI12301 Digital PEI Body pH Electrode is a combination digital pH electrode designed for on-site and field use, featuring a durable PEI (polyetherimide) body for superior resistance to mechanical stress and chemical exposure. It is ideal for water, wastewater, and environmental testing in harsh outdoor conditions.
This electrode includes a single ceramic junction, gel electrolyte, and a spherical glass sensing tip for general-purpose measurements. It also features an amplifier and a matching pin to reduce electrical noise and reference junction errors, ensuring reliable and stable measurements even in environments with high conductivity or interference.
The HI12301 connects to compatible Hanna Edge meters via a 3.5 mm jack, offering a smart, plug-and-play experience with internally stored calibration and sensor data.
Key Features
Digital Smart Electrode: Stores calibration history and electrode ID, auto-recognized by Hanna Edge meters.
Rugged PEI Body: Shock-resistant and chemically durable, perfect for field applications.
Matching Pin: Enhances measurement stability by compensating for ground loop effects and electrical noise.
Gel Electrolyte: Maintenance-free, ideal for portable and on-the-go testing.
Built-in Temperature Sensor: Enables automatic temperature compensation for accurate pH readings.
Spherical Tip (Ø 7.5 mm): Provides consistent contact for general-purpose liquid testing.
Amplified Signal Output: Minimizes interference from environmental or industrial noise.
