Hanna Instruments GroLine Direct Soil pH Tester with Removeable Sleeve

Better Features for Better Testing
An onscreen stability indicator ensures the highest level of confidence in your results. The selectable auto-off feature prolongs battery life for peace-of-mind and energy savings if the meter is accidentally left on.

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.

Long Battery Life
The included CR2032 Li-ion battery provides up to 1000 hours of continuous use. The battery icon will blink to let you know it is time to change the battery so you never miss a measurement.

Unique Open Junction with Removable Sleeve
When the readings become slow, simple remove the sleeve for quick cleaning and new electrolyte. Having a clean probe with a fresh reference electrolyte will improve performance and extend the life of the tester.

Conical Glass Tip
The conical shaped tip design allows for penetration into soil and soil slurries.

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

Cleaning Solution for Soil and Humus Deposits
Your Soil pH Tester comes with cleaning solution that has been 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.

pH 4 & 7 Buffer Sachets
When performing a pH calibration it is important that the correct buffers are used. We include some start buffers to get you going. The single-use sachets are individually sealed so you use fresh buffer each time you calibrate.

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.
