The Eureka Trimeter combines the same electronics as the Manta’s multiprobe and interface, in a smaller, lighter housing. Simply select temperature, and/or depth and then choose an extra parameter from the available sensors list to make your required multiprobe. It provides maximum field performance at the lowest possible cost.

Ideal for spot tests / profiling or for unattended use as a self powered logger. It can also be connected to a telemetry system for remote applications.

Data can be viewed on a range of display devices including the Amphibian2 (Windows Mobile), PC/Laptop (Windows), or Leapfrog Bluetooth (Android, BT Enabled Windows device).
