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. HI 99121 can test the pH of soil directly or after preparation of a diluted sample. In order to measure the pH directly, the kit includes a plastic auger to perforate the ground. The pH and temperature can be directly tested with the 3-in-1 conic shaped electrode with even a slightly moist soil. 

For higher degrees of accuracy, or for stony ground where the electrode may be damaged, use the specially made HI 7051 test solution. This solution is included in the package to help you measure pH more precisely by diluting a sample of the soil in it. The kit naturally includes a pH meter. However, in order to facilitate fast and reliable measurements, the supplied pH meter is HI 991001 complete with HI 1292D electrode, pH 4 and pH 7 calibration sachets, beaker, auger and a practical and rugged carrying case. HI 991001 is waterproof and sophisticated yet engineered for its simplicity.

The 3-in-1 pH electrode, HI 1292D, has been designed for direct soil measurement. It has a conic, rugged tip and can be directly inserted in moist or soft soil. The electrode incorporates a temperature sensor right near the tip to enable it to measure and compensate for the temperature quickly. It also houses a miniaturized amplifier to provide greater stability in spot measurements. The dual-level LCD shows the pH value from -2 to 16 in hundredths of units. It also displays the temperature on the secondary level at the same time. With a menu-driven custom microprocessor, the user is helped with clear prompts during operation and calibration.
