Standardní pH elektroda Greisinger s konektorem BNC 102090

The Greisinger Standard pH Electrode with BNC connector (102090) is a general-purpose combination electrode built for reliable pH measurement in laboratory and process environments. Unlike many basic electrodes, it uses a polymer gel electrolyte and a ceramic diaphragm, which reduce maintenance and make it suitable for a wide range of aqueous samples. The glass shaft is 12 mm in diameter and 120 mm long, with a fixed 1 m cable and BNC connector for direct connection to compatible meters.

Highlights

• Measurement range: 0.00 to 14.00 pH
• Operating temperature: 0 to +80 °C (short-term up to 100 °C)
• Reference system: Ag/AgCl with ceramic diaphragm
• Polymer gel electrolyte for low maintenance
• Glass shaft, 12 mm diameter, 120 mm length
• BNC connector with 1 m fixed cable
• Response time: < 30 seconds
• Zero point: pH 7.00 ± 0.25
• Slope: > 58 mV/pH at 25 °C
• Max. pressure resistance: 1 bar

In daily use

This electrode is ready to use after a short conditioning in pH buffer. The gel electrolyte does not need refilling, and the ceramic diaphragm provides stable and fast readings. The BNC connector ensures compatibility with most pH meters, and the 1 m cable gives enough reach for bench or field setups. Store the electrode in storage solution when not in use to maintain performance.
