DESCRIPTION:
HI99121 - The HI99121 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. HI99121 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 4-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 HI7051 test solution. This solution is included in the package to help you measure the 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 complete with HI1292D electrode, pH 4 and pH 7 calibration sachets, beaker, auger and a practical and rugged carrying case. The meter is waterproof and sophisticated yet engineered for simplicity. The 4-in-1 pH electrode, HI1292D, 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 boost the signal and provide greater stability in spot measurements. The dual-level LCD shows the pH value from 0 to 14 in hundredths of units (0.01). 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. The batteries provide up to 1500 hours of continuous operation and indicate the battery level at any time. Calibration is completely automatic and the meter recognizes the buffers too. Any value set by the user as well as the calibration data are retained even during battery replacement. The meter is ergonomic and has been made for single-handed use. Together with the meter you will also receive a handy booklet which explains how pH should be measured as well as general information about the correct limits in greenhouses, nurseries, fertilizer solutions as well as fruit and vegetable. HI99121 is supplied complete with portable waterproof pH meter, HI1292D pH electrode, ground auger, beaker, HI7051M soil preparation solution, pH 4 & 7 cal. solutions and a rugged carrying case.
