This kit is a versatile combination of instruments for measuring pH, EC and “salt activity”
The Model 550 is a portable, versatile pH meter that has 2 pH calibration points and automatic buffer recognition.
Simultaneous reading of pH and temperature. PH resolution to 3 decimal places and calibration to 1, 2 or 3 points.
Determination of pH directly in the soil or in the laboratory
Measurement of activity, pH and electrical conductivity of activity.
A simple microprocessor-controlled measuring device with an ion-selective electrode for determining the concentration of nitrate ions in liquids.
Measuring acidity as well as the concentration of salts, the value of acidity is the most important indicator used when adjusting plant nutrition.
