Replacement sensors for soil moisture meter

Monitor the moisture available to your plants with this meter and sensor (sold separately). Use the meter to effectively schedule irrigation according to the plants' requirements. Prevents soil spoilage due to excessive water and poor drainage by continually monitoring soil moisture. Meter also helps to eliminate under-irrigation--making fertilizer applications more efficient. The meter is housed in a rugged ABS plastic case. It features reliable, temperature-stable semiconductor technology with an internal battery and calibration check. The membrane front panel is easy to use. Spring-loaded binding posts allow positive contact with the sensor. Sensor is made from gypsum, cast around two stainless steel electrodes. Bury the sensors at different levels, based on the plant's root depth. Connect the lead wires to the meter and get immediate readings of available soil moisture. A convenient carrying case and irrigation charts are included.
