The HI12943 is a pH electrode for the direct measurement of pH in soil and soilless media. The HI12943 is a glass body, refillable, single junction pH electrode with a DIN connector that is compatible with the HI9814 Groline portable pH/EC/TDS meter. This electrode has a triple ceramic junction in the outer reference cell and the conic pH sensing tip is made with low temperature glass.

The HI98331 Soil Test is a pocket tester specifically designed to directly measure soil conductivity (EC) and temperature. With a compact size, single button operation, and automatic calibration, Soil Test is an excellent choice for taking direct conductivity measurements in soil.

• No need for soil slurries with the steel penetration electrode.
• Integrated temperature sensor for automatic temperature compensation.
• Great for environmental and agricultural testing.

Designed to bring simplicity to pH testing of soil, the HI981030 GroLine Soil pH Tester is designed for taking direct pH measurements in soil for environmental and agricultural testing. The built-in probe features an open reference junction, conical glass tip, and a removable sleeve design making it ideal for measuring the pH of soil.

The HALO2 GroLine Wireless pH Tester (HI9810302) is designed to bring simplicity to pH testing of soil for environmental and agricultural purposes.
