SI Analytics หัววัดความเป็นกรดด่าง Sentix Sur, 103646

Model: Sentix Sur, Order no. 103646. The SenTix Sur is a pH surface combination electrode designed for low‑maintenance, accurate pH measurement of surfaces and shallow or small-volume samples. It provides direct surface pH determination where conventional immersion electrodes are unsuitable and is intended for laboratory and field surface-measurement applications.

Key Features:

• Measuring range: 2 … 13 pH
• Temperature range: 0 … 50 °C
• Membrane shape: Flat; Membrane resistance: < 1 GΩ
• Shaft: Glass, length 120 mm, diameter 12 mm
• Diaphragm: Split ring; Reference electrolyte: Referid®
• Connection: S7 plug head (without cable); Temperature sensor: none

Advantages:

• Low‑maintenance design optimized for repeated surface measurements.
• Flat membrane and split‑ring diaphragm enable reliable contact on planar or shallow samples.
• Gel/reference electrolyte system (Referid®) and low membrane resistance support stable, accurate readings.
• Compact glass shaft (120 mm × 12 mm) provides convenient handling for laboratory and field use.
