    อุปกรณ์วัด pH (pH meter for direct measurement of the pH of the soil)

    HI 99121
    pH meter for direct measurement of the pH of the soil

    HI 99121 is designed to measure the pH of the soil in agriculture. Thanks to HI 99121 is in fact can either proceed to the direct measurement of the pH in the soil, both measure a solution prepared with a sample of the soil itself. The instrument is supplied with all necessary accessories for both procedures of measurement: for the direct measurement, we practice first a hole in the ground using the proper drill included, you insert the electrode and the measurement is taken, taking care to moisten the land should this be too dry. For more accurate results or in soils with the presence of stones that may damage the electrode, you can instead prepare a sample with the ground and the solution HI 7051M provided, let stand a few minutes and then proceed to the measure. HI 99121 is a tool technologically advanced, but very easy to use. Provides on the display simultaneously the reading of pH and the temperature. The glass electrode supplied with HI 1292D, with integrated temperature sensor, is designed to give the best results as far as soil pH and substrates used in greenhouses and nurseries.
