WET-2-K WET KIT for Water Content, CE and Temperature


Delta T


-  Measures Water content, EC and Temperature
-  Complete kit with readout unit & case

Sensors are normally ordered as a complete kit that includes a WET Sensor, an HH2 Moisture Meter and a handy carry case. There are three types of Kit – each with a different set of substrate calibrations, including coir, peat and mineral wool. Please see below for further information on substrate calibrations and kits.

Wet-2-K is available with various sets of substrate calibrations.

The Sensor measures: Soil Humidity, EC, Temp.
Sensor for use in: Outdoor

In just 5 seconds the WET Sensor checks 3 crucial variables that influence plant growth: water content, temperature and pore water conductivity (ECp), the EC of the water that is available to the plant.

- Measures water content, EC and temperature
- Measure directly within the root zone
- Quick controls of growing conditions
- Ideal for precision irrigation

Vital tool for precision horticulture

The WET Sensor is used throughout horticulture, especially by soft fruit growers and for crops grown in protected environments, where correct growing conditions are critical to both yield and flavour. The compact sensor can be inserted directly into the growing medium with minimal disturbance to either roots or shoots, and provides information for process optimisation, checking growing condition uniformity and precision irrigation.

[1]Permittivity is a measure of the dielectric properties of materials, e.g. soils and substrates.
[2] Soil moisture accuracy refers to errors after applying a soil-specific calibration, within 10°C of calibration temperature.
