pH Electrodes, Schott BlueLine Gel, Liquid and Special

Overview

The Schott BlueLine family of pH electrodes is made up of three ranges. For general use the robust electrodes with gel electrolyte and plastic shaft, for more critical measurements the liquid electrolyte sensors and for unique applications special sensors.

The gel electrolyte and the liquid electrolyte sensors are available with plug head or fixed cable of various lengths with either DIN or BNC type plug, and are also available with integrated temperature sensors

The special electrodes range includes pH electrodes for surface measurements, for small sample amounts, for ultrapure water and emulsions or measurements in semi-solid samples. The range also includes redox electrodes and a conductivity electrode for media with low ionic content.

An accurate and fast measurement is ensured by precision manufacturing and employment of high quality material such as low-resistance A-type membrane glass, low temperature L-glass or the unique platinum diaphragm.

Features of the Schott BlueLine Electrodes:

Comfortable handling, stylish design and reliable function
Available gel electrolyte, liquid electrolyte and special sensors
Wide variety in the basic family for standard laboratory applications, made from universal A-type membrane glass for short response time
Liquid electrolyte electrodes with unique platinum diaphragm and refill port slider
Each electrode has an individual serial number
