250-40561 MAS-1 Soil Moisture Sensor
250-40561 MAS-1 Soil Moisture Sensor

MAS-1 Soil Moisture Sensor 4-20mA

$330.00

Ships in 5 - 7 business days from time of order.

Model: 250-40561

The 250-40561 MAS-1 Soil Moisture Sensor offers a standard 4-20 mA output that is common with PLCs, Irrigation controllers and Data Loggers. 5M (16ft)) Cable lenght is standard, custom cable length up to 250ft)

The MAS-1 determines volumetric water content (VWC) by measuring the dielectric constant of the media using capacitance/frequency domain technology. The sensor uses a 70 MHz frequency, which minimizes salinity and textural effects, making the MAS-1 accurate in almost any soil or soil-less media. Factory calibrations are included for mineral soils, potting soils, and rockwool.

The MAS-1 delivers research-grade accuracy at a price that makes large sensor networks economically practical. You can adequately characterize your site with sensors at multiple depths and locations, even if you're on a tight budget.
