Solinst Eureka EasyProbe
Cost-effective multiparameter water quality sonde in two versions: EasyProbe20 measures temperature, dissolved oxygen, conductivity and pH/ORP, and EasyProbe30 adds turbidity.

Part no.: Trim DO
Trimeter, the most compact Eureka multiprobe, fitted with an optical DO sensor and temperature. A depth sensor is optional.
Prices are given in the quote we send you.
The Trimeter uses the field-proven electronics of the Manta+ probes in a smaller, lighter body. It holds one sensor of choice plus temperature and depth, here an optical DO sensor.
The optical sensor uses the EPA-approved luminescence lifetime method, compensates for temperature and salinity, and the cap typically lasts more than 6 years. With a battery pack the probe logs on its own, and it can feed a telemetry station over RS-232, SDI-12 or Modbus.
Supplied with a weighted sensor guard, storage and calibration cups, internal memory, marine connector, electronic manual and software. The data cable and USB adapter are not included and are ordered separately.

Eureka
Part no.: Manta+20
Portable yet rugged multiprobe with temperature, pH, conductivity and optical DO, with ORP and depth as options. Fits in a backpack and suits spot checks and profiling.
Eureka
Part no.: Manta+30A
Multiprobe with wipered turbidity, temperature, pH, conductivity and optical DO. Light enough for spot checks and profiling, tough enough for extended deployments.
