DICKEYjohn PM300 Planter Monitor
The PM300 provides population data, area data and blockage monitoring for up to 16 rows. The PM400 is also available for up to 36 rows.
For versatility and flexibility, you can’t beat the PM Series of planter monitors. Provides population, seed spacing, ground speed, and area monitoring for up to 16 rows (PM300) or 36 rows (PM400). The units will even monitor accessories and are equipped with high and low-population warning alarms. For the off-season, the series offers speed and area modes for quick, simple field assessments. Because PM Series monitors store their data in nonvolatile memory, you’ll never have to worry about losing information when power is cut off.
