• Dual-level LCD
• Plastic Auger for easy ground penetration

The HI 99121 kit has been designed to address the question of correct and rapid measurement of pH directly in soil. Every item in this kit has been made to facilitate measurements in the field without compromising accuracy. For higher degrees of accuracy or for stony ground where the electrode may be damaged, use the specially made soil preparation solution included in the package. The dual-level LCD shows pH value from -2 to 16 with 0.01 resolution. With a menu-driven custom processor, the user is helped with clear prompts during operation and calibration.
