STELZNER® agricultural measurement systems

Straightforward monitoring of plant nourishment

The PE controller is designed for simple on-site monitoring of plant nourishment. It can measure the potential absorption of nutrient salts under the same conditions as the nutrient salt absorption through the roots as the time of the measurement. This easy-to-use instrument can display on-site whether there is too little, too much, or the right amount of available fertilizer present.

The measurement is taken directly in the substratum, compost, garden soil, or greenhouse. This allows you to monitor the nutrient status potted plants, balcony boxes, container plants and vegetable beds. You can be sure that you're not using too much or too little nutrients with the PE controller. This handy tool is a must for every hobby gardener. The probe is 25 cm long and has a diameter of 10 mm.
