Combined pH Electrode with Ceramic Junction

Refillable glass pH electrode for laboratory applications, with BNC connector and 1 m cable.

0 to 90 °CTemperature Range

Overview

The AK1004 is a refillable combined glass pH electrode with a ceramic junction, built for accurate laboratory measurements. The refillable reference lets you top up the electrolyte to maintain a stable junction potential and extend working life, while the ceramic junction suits clear aqueous samples and general laboratory use.

Key features

Maintaining your pH electrode

Regular cleaning ensures measurement accuracy and extends electrode life. Follow this procedure periodically.

1
Prepare a small beaker with electrode cleaning solution (pepsin)
2
Leave the electrode tip immersed in the solution for 30 minutes
3
Rinse the electrode in distilled water
4
Remove excess water using a soft paper towel
5
Store the electrode in KCl 3M potassium chloride solution for 1 hour
6
Your tester is now ready for calibration — always use fresh calibration solutions
