Trimeter™

Eureka’s new Trimeter is the simple, low cost solution when you need quality data, but fewer sensors.

Features:

• Choose any Eureka sensor and add Depth and/or Temperature
• Use as a spot checker/profiler, self-powered logger, or with telemetry
• LED indicators for sonde status (power, logging, communication)
• Uses off-the-shelf “D” replaceable batteries
• Compact, rugged design
• Works with all Eureka’s display options, such as the Amphibian2 (Windows Mobile), PC/Laptop (Windows), or Leapfrog Bluetooth (Android, BT Enabled Windows device)

The new Trimeter incorporates the field-proven electronics of Eureka’s Manta Multiprobe and its user interface, with a smaller, lighter instrument body. Select temperature, and/or depth (vented, non-vented), along with any one of Eureka’s sensors (excluding ISE’s). For instance, choose Chlorophyll plus Temperature and Depth, or just Chlorophyll. The Trimeter gives you maximum field performance at minimal cost.
