The 257 is a solid-state, electrical-resistance sensing device with a granular matrix that estimates soil water potential from 0 to -200 kPa. It connects directly to a datalogger.

The "-L" on a product model indicates that the cable length is specified at the time of order.

  • Compatible with most Campbell Scientific dataloggers
  • Contains blocking capacitors in its cable that minimizes galvanic degradation and measurement errors due to ground loops
  • Rugged, long-lasting sensor
  • Buffers salts in soil
  • No maintenance required
