Measuring instruments for soil moisture and water monitoring, using sensors, tensiometers and data loggers

Bambach-Switching sensors

M-sensors are pressure manostat monitors that provide the tensiometer with switching properties. These pressure manostat monitors are membrane switches for applications in the low voltage range (e.g. 24 VDC) where a defined, limited switching range can be implemented. They allow infinitely variable adjustment of the switching point, but with no scaling.
For automatic irrigation, M-sensors can either switch the solenoid valve directly or they can be connected to an automatic watering system.

The TensioSwitch has the same function as an M-sensor, but has contactless switching, an LED switching display, and requires a power supply. It is well suited for direct switching or use with a relay.

PET 2000

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... ...more Topseller
