Ranger Series

The TPS Ranger Series is a professional range of handheld multiparameter water quality meters designed for aquaculture, environmental monitoring and water research applications. Built for use in the field, Ranger meters combine rugged, waterproof construction with laboratory-grade accuracy — giving operators reliable readings of pH, dissolved oxygen, electrical conductivity, ORP and turbidity wherever they’re needed.
Each Ranger unit features a multi-port design that supports interchangeable smart sensors, allowing users to configure their meter for the parameters that matter most to their operation. Whether you’re monitoring a fish hatchery, managing a recirculating aquaculture system, or conducting water quality surveys in the field, the Ranger Series delivers the precision and flexibility professional operators demand.
Manufactured by TPS — a Brisbane-based Australian company with over 50 years of experience in water quality instrumentation — the Ranger Series is backed by local support, Australian calibration standards and a network of specialist distributors. All sensors are field-replaceable, reducing downtime and long-term maintenance costs.
Trusted by aquaculture producers, environmental consultants and research institutions across Australia, the TPS Ranger Series sets the benchmark for handheld water quality monitoring in demanding conditions.
