Activity measurements and monitoring crop nourishment

The PET 2000 activity meter can measure the potential absorption of nutrient salts under the same conditions as the actual nutrient salt absorption through the roots. This means that the dissolved salt content is measured in the soil and substrata and thus corresponds to the direct "activity" within the plant canopy. The displayed units are g/l (e.g., grams of salt per litre of substratum). All related soil properties (such as fertilizer concentration, soil humidity, volume density and temperature) and taken into account for the measurement.

The accompanying technical manual can then be used to properly evaluate the measured salt content. In landscape architecture, tree schools, nursery gardens, public parks, forests and all other areas where plants are cultivated, this meter helps to verify and monitor your plan of action. You can optimize your cultivation results with the PET 2000.

When high salt content is being measured, the nitrate test strips (art. no 1100) can be used to differentiate between nitrogen and accompanying salts. The AM probe is available in a variety of lengths (25, 50 or 75 cm with 10-mm diameter) to fit the application. Longer probes are available on request. The AM probe is made from stainless steel and has a 3-cm measuring tip. The probe is maintenance-free. It come with a 9-Volt battery and a splash-water resistant enclosure.
