Hanna Soil pH/Temp Waterproof Meter HI 99121. Measure pH of Soil Directly with a Special pH Electrode Amplified, ATC Electrode The advanced HI 1292D incorporates a temp sensor and has a tiny amplifier for excellent stability and quick response. Automatic Calibration Choose between six memorized buffers to automatically calibrate the instrument. Messages on the Display The operator is helped by graphic symbols visualized on the LCD. Supplied Complete The ground auger allows direct measurements or for greatest accuracy use the beaker & soil preparation solutions.The 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. 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 the pH more precisely by diluting a sample of the soil in it. The 4 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 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. 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. Any value set by the user as well as the calibration data are retained even during battery replacement. HI 991000 is ergonomic and has been made for single handed use.
