Water Quality Sonde

Trimeter – Three Parameters at the Lowest Possible Cost

The Trimeter holds any one sensor*, plus temperature and depth sensors (both are optional). Versatile, rugged, and precise monitoring for groundwater and surface water.

*Exceptions include PAR, CO2, ISE’s and Transmissometer.

Trimeter Water Quality Sonde

Versatility & Performance

Solinst Eureka’s communication cables are compatible with all Manta and Trimeter multiprobes. Trimeters are as versatile as our flagship Manta multiprobe line when it comes to applications variety.

One Platform, Infinite Applications

Connect the Trimeter to one of our field display options for sampling in the field, or add a battery pack for autonomous long term deployments. Connect to a telemetry station for viewing real time data in the cloud.

LED Diagnostics

Instant field health checks via integrated status LEDs, ensuring your probe is ready before deployment.

Extended Power

Optional battery pack transforms the Trimeter into a true autonomous logging device.

Universal Ecosystem

Compatible with all Solinst Eureka software apps, Windows, iOS and Android. Excellent choice for autonomous Turbidity logging.
