Overview

Use the SRM100 soil resistivity and pH meter to:

  • Work faster – An SRM100 can curtail the time it takes to complete AC tower pylon inspections, certain ECDA surveys, or other assessments. That's because traditional readings with a four-pin process can take up to 20 minutes each whereas the SRM100 measures soil pH and resistivity simultaneously in less than two minutes.
  • Improve accuracy – The single-probe configuration eliminates errors due to miscalculations or incorrect probe spacing and depth.
  • Lower costs – The SRM100 helps you save on groundbed installations by enabling your crew to spend less time setting up measurement equipment and more time digging.
Features
Feature Benefit
Three probe options Each SRM100 comes with one or more probes. Choose the option that's best for you: a bell hole probe, a subsurface probe, or both.
Protective case No matter which probe configuration you choose, your SRM100 and probe(s) will be housed in a crush-proof, water-resistant case for protection from the elements in outdoor applications.
Digital circuitry Digital circuitry allows for repeatable readings with improved accuracy.
Self-calibration An internal calibration circuit allows the SRM100 to self-calibrate in the field.
LCD display The two-line display is easy to read in most light conditions.
Accessible batteries The battery is accessible via a door on the back of the unit for easy replacement.
