The Trimeter is a new "mini-probe" launched as part of the Manta+ line of multiprobes. It offers all the features and quality of the Manta+ probes in a smaller package that can incorporate any one of Eureka's sensors, plus temp and depth, to create a custom Tri-Meter.
The Manta+ 20 contains the "Big Four" configuration of temp, pH, conductivity and optical DO, with optional depth and ORP - in a 1.95" diameter housing.
A popular configuration of the Manta+ 25 contains temp, pH and conductivity plus turbidity.
The Manta+ 30 comprises one of the most frequently requested configurations - of temp, pH, conductivity, optical DO, and turbidity (with optional depth and ORP).
The Manta+ 35 contains all the sensors of the 30 plus 2 optional medium sensors and any 2 small sensors listed to the left. The 35 includes a Central Wiping System at no additional cost.
The Manta+ 40 contains all the sensors of the 30 plus 3 optional medium sensors and any 3 small sensors listed to the left. The 40 also includes the Central Wiping System.
