Product Description
Hanna Instruments HI12943 is a specialized GroLine pH electrode designed specifically for direct soil and soilless media measurements. Featuring a robust glass body and refillable single junction design, the HI12943 employs a triple ceramic junction in the outer reference cell, optimizing electrolyte flow for stable and precise readings—even in tough samples such as soil slurries and various soilless substrates including rockwool, coco, and perlite.
The low temperature glass conic tip (12 × 12 mm) allows for easy penetration into soil and ensures optimal contact with the testing medium. An integrated amplifier and built-in temperature sensor facilitate automatic temperature compensation for reliable and accurate pH measurement across a temperature range of -5°C to 70°C. The electrode connects to compatible meters via a quick connect DIN connector and includes a sturdy 1 m cable for versatile handling during laboratory, agricultural, and environmental use cases.
- Triple ceramic junction enhances reference cell performance for fast and stable measurements.
- Conic, low temperature glass tip is ideal for direct soil insertion and difficult samples.
- Glass body provides resistance to aggressive chemicals and temperature fluctuations.
- Reinforced with an integrated amplifier for consistent signal in challenging field conditions.
- Suitable for use in agricultural laboratories, soil science research, water quality monitoring, and commercial greenhouse applications.
- Compatible exclusively with the HI9814 GroLine portable pH/EC/TDS meter.
- Maximum pressure rating of 0.1 bar supports reliable operation in varied environments.
- Provides rapid response and easy maintenance with refillable electrolyte system (3.5M KCl + AgCl).
- Set includes the HI12943 pH electrode with inbuilt temperature sensor and attached cable with DIN connector.
Ideal for industrial agriculture, research labs, commercial horticulture, hydroponics, and environmental field testing.
