GroLine HALO2 Wireless pH Tester

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

• Open-source Bluetooth allows easy integration into current data logging systems
• IP65 water resistant protection
• Specialized electrode for spot checking the pH of soil and soil slurries
• Equipped with everything you need for successful testing right out of the box

GroLine is specially designed for testing a wide array of growth mediums including: coco fiber, organic soil, rock wool, clay balls, recycled plastic balls, bog, hydroponic systems and more!

Universal Connectivity

The open-source Bluetooth® protocol allows easy integration with the Hanna Lab App and current Laboratory Information Management System (LIMS). The HALO2 GroLine Wireless pH Tester (HI9810302) is GLP compliant.

IP65 Water Resistant Protection

The housing of the HALO2 GroLine Soil pH Tester is rated IP65 meaning it has a high level of protection against particles and dust, and protection against the ingress of water from jets. This makes it ideal for outdoor use.

Pocket-Sized

The compact size makes the Soil pH Tester ideal for on-the-go testing. A large LCD display provides at-a-glance readings from any angle and single button operation streamlines the testing process for any user.

Unique Open Junction with Removable Sleeve

When the readings become slow, simply remove the sleeve for quick cleaning and a new reference electrolyte. This will improve performance and extend the life of the tester.

PVDF Body

Polyvinylidene fluoride (PVDF) is a durable plastic that is resistant to most chemicals and solvents used for disinfection, including chlorine (bleach).

Conical Glass Tip

The conical-shaped tip design allows for penetration into soil and soil slurries.

Cleaning Solution for Soil and Humus Deposits

Your HALO2 GroLine Soil pH Tester comes with cleaning solution that is engineered to keep your electrode free from organic materials found in soil. This concentrated combination of detergents cleans your tester quickly and effectively so that your tester stays in optimum condition.

Easy Calibration

HALO2 can be placed right into our calibration buffer sachets for easy calibration. Using a Hanna calibration sachet ensures your buffer is always fresh.

Storage Solution

Proper storage of your electrode will ensure reliable measurements and a long electrode life. Our storage solution is specially formulated to keep the pH glass hydrated while minimizing organic growth. The HALO2 GroLine Soil Wireless pH Tester is designed to bring simplicity to pH testing of soil for environmental and agricultural purposes.
