Hanna HI981030 GroLine Soil pH Tester

The Hanna HI981030 GroLine Soil pH Tester is a compact, waterproof, and easy-to-use digital pH meter designed specifically for direct soil pH measurement. Built with an integrated probe optimized for soil environments, this tester provides fast, accurate readings for growers, researchers, and hobbyists who need to monitor pH directly in the field without additional tools or complicated preparation.

Features

• Specialized for Direct Soil pH Testing
  Designed with a built-in, soil-specific probe, the HI981030 allows you to insert the sensor directly into moist soil or soil slurries. As a result, you can obtain immediate and reliable pH readings without the need for separate accessories.

• Highly Accurate and Sensitive
  Offers a high resolution of 0.01 pH and an impressive accuracy of ±0.05 pH at 25°C, ensuring precision for agricultural or scientific applications. Therefore, you can trust it for critical soil pH adjustments.

• Automatic Calibration
  Supports one- or two-point automatic calibration, compatible with standard buffer solutions. Moreover, this simplifies the process of maintaining accuracy over time and improves ease of use for non-technical users.

• Energy Efficient with Auto-Off Options
  To conserve battery life, the device features an auto-off function that can be set to 8 minutes, 60 minutes, or disabled entirely based on user preference. Consequently, it balances energy savings with workflow flexibility.

• Exceptional Battery Life
  Powered by a single CR2032 lithium-ion battery, the tester operates for up to 1,000 hours of continuous use. In addition, its low power consumption makes it ideal for frequent field testing.

• Compact, Waterproof, and Lightweight
  Built for durability and portability, the HI981030 is IP67-rated waterproof and weighs just 44 g. Thus, it’s easy to carry in your pocket or tool bag for on-the-go soil testing.
