Greisinger GE120 elétrodo de pH de substituição, eletrólito em gel, ficha BNC, haste de 120 mm, cabo de 1 m 474135

Laboratory technicians and water-quality analysts use the Greisinger GE120 replacement pH electrode to keep their Greisinger GMH 35xx or GMH 55xx series meters measuring accurately. The 120 mm glass shaft and gel-filled reference system provide stable readings across a wide range of aqueous samples.

Key specifications

• Measuring range: 0 to 14 pH
• Temperature range: 0 to +80 °C
• Shaft material: glass, diameter 12 mm, length 120 mm
• Reference system: Ag/AgCl, ceramic diaphragm, gel KCl electrolyte
• Connector: BNC plug, 1 m cable
• Response time: < 30 s (90%)
• Zero point: pH 7.00 ± 0.25; slope: > 58 mV/pH at 25 °C

Why choose it

The gel electrolyte requires no refilling and reduces maintenance, while the ceramic diaphragm ensures reliable contact with the sample. The BNC connector plugs directly into compatible Greisinger meters without adapters.

Ideal use cases

• Routine pH checks in laboratories and water-analysis labs
• Field measurements with portable Greisinger meters
• Replacement of worn or dried-out electrodes

Good to know

The electrode is a direct replacement for Greisinger pH meters with BNC input. Store the electrode in KCl storage solution when not in use to prolong its life.
