Meter - Model 4-20 - E-240-MAS-1 - Milliamp Volume Soil Moisture Sensor
The MAS-1 4-20 milliamp sensor is the first current-based sensor to use Decagon`s trademark 70 MHz technology. This sensor offers a standard 4-20 milliamp output that is common with PLCs and irrigation controllers. With the 4-20 mA interface, cable lengths over 250 feet are possible.
Research Grade Accuracy
Like other Decagon soil moisture sensors, the MAS-1 measures soil moisture accurately without the sensitivity to electrical conductivity and variation in soil types that have plagued inexpensive sensors in the past.
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. And the MAS-1`s ultra-long cable lengths give you even more flexibility to put your sensors where you want them.
Engineered for Accuracy
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.
Reasons to pick the MAS-1
- IF YOU NEED A 4-20 MILLIAMP SENSOR
- IF YOU NEED CABLE LENGTHS GREATER THAN 250 FEET
