STELZNER® agricultural measurement systems

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

Type-VII advisory kit

For measuring pH and conductivity

The Type-VII combination kit consists of two instruments: the ph AGRAR 2000 for measuring pH in soil and liquids and the EC 2000 for measuring conductivity in liquids.

These two instruments are your ideal companions when monitoring the fertilization of hydroponic crops. The pH AGRAR 2000 allows you to monitor the pH. This microprocessor-controlled meter enables you to make quick and precise measurements in solutions such as irrigation water and fertilizer solutions. A glass pH piercing electrode allows you to determine the pH level directly in the soil or substratum. The meter features automatic calibration.

It displays the electrode conductivity slope for monitoring the glass pH piercing electrode. A warning tone is emitted if the sensitivity level is too low. The sturdy housing is built for the rough conditions of agricultural field work. The EC 2000 is used to measure conductivity. EC value analysis is a critical component in fertilization, soil-free cultivation, closed cultivation, hydroponics, or salt-sensitive crops.

With its ability to measure up to 200 mS/cm with the glass-platinum conductivity electrode, the
EC 2000 is also suitable for monitoring basis solutions. It is temperature compensated and equipped with a specific conductivity electrode with integrated temperature probe.
