Welcome to STELZNER^®

For measuring the pH in soils and liquids, use our pH-AGRAR 2000 for monitoring crop

Activity measurements directly in the soil, monitoring plant nutrition, pH measurements in liquids, measurements of salinity

Measurements of dissolved salts, water hardness, temperature, EC or TCS in liquids and filtered soil solutions, with the Pockettester and Flow-Meter: for pipelines, hydroponics, ponds, swimming pools and in the laboratory

Measuring in soil and in liquids, with our MULTI ISE for determining individual nutrients and the Pockettester for pH, conductivity and temperature

Our advisory kits for measuring pH: the pH AGRAR 2000, the PET 2000 for measuring nutrient salt intake, the MULTI ISE for determining individual nutrients, the EC 2000 for measuring conductivity, the PE Controller for monitoring crop nutrients, the MULTI 2000 for measuring activity, conductivity and temperature, and the Type-X, Type-V, Type-VII and Type-III combination kits

Featured in our product line: Soil kit for easily determining the nitrate content in the field, with a micro-processor-controlled measuring instrument, ion-selective electrode and nitrogen/nitrate quick test
