Industrial DR 760A Soil Testing Device

Industrial DR 760A Soil Testing Device from Soiltest, Inc. is a rugged, field‑ready instrument designed for engineering soil assessments. The model is described as a DC device that operates at a low current—1 milliampere—making it suitable for precise electrical soil measurements in environmental and geotechnical projects. The DR 760A is referenced in official maintenance guidance for Soiltest DR series instruments (including DR760A, DR762M, and DR762A), which notes that general maintenance is not required; instead, monthly maintenance consists of checking and replacing the battery as needed, typically with a 1.5V penlight cell, along with after‑use cleaning and a battery level check. For functional maintenance, the manual recommends contacting the manufacturer or qualified service personnel. The DR760A also appears in groundwater monitoring planning materials, underscoring its role as a field instrument used for subsurface measurements within environmental site investigations. As part of the DR series, the DR 760A emphasizes straightforward operation, durable construction, and reliability—qualities engineers rely on when performing soil characterization, remediation testing, or construction site assessments.
