RINKO Fast DO Sensor

The RINKO Series phosphorescent dissolved oxygen sensor boasts a 90% response time of less than 1s (in air at 25℃), allowing for a seamless instrument integration for continuous profiles.

RINKO-FT (ARO-FT), allowing greater accuracy and stability by incorporating high-quality multipoint calibration and improved sensing method.

RINKO-I / I D (ARO-USB/ARO1-USB) (1-100m), an autonomously deployable data logger with a fast response optical DO sensor.

RINKO-III (ARO-CAV), an analogue output version with a fast optical DO and a temperature sensor.

RINKO-Profiler, provided with a fast-responding DO sensor as standard.

AAQ-RINKO, a water quality profiler redesigned with an optical fast response DO sensor.

RINKO-W (AROW2-USB), an autonomously deployable data logger for long-term DO measurements.

RINKO-EC (ARO-EC), designed for aquatic eddy covariance measurements.

INFINITY Miniature Multi-Channel Sensors

The INFINITY series offers built-in recording type measuring instruments whose observations settings can be set by direct input from a PC via a USB or miniSD card.

INFINITY-EM (AEM-USB), an autonomously deployable EM current meter with a data logger.

INFINITY-CT (A7CT-USB), an autonomously deployable data logger for temperature and salinity measurements.

INFINITY-CLW (ACLW2-USB), an autonomously deployable data logger for long-term chlorophyll and turbidity measurements.

INFINITY-Deep (AEMD-USB), available at 6,000 meters depth.

INFINITY-CTW (ACTW-USB), a conductivity sensor that can be deployed for more than a few months without maintenance.

INFINITY-Turbi (ATU75W2-USB), an autonomously deployable data logger for long-term turbidity measurements.

Multi-Excitation Chlorophyll Fluorometer

Multi-Exciter for high sensitivity fluorescent measurements in turbid water, with 9 wavelength excitations and multiple possible parameters including turbidity, temperature and depth.

DEFI2 Miniature 1-Channel Sensors

The DEFI2 Series presents accurate, small and light weight temperature, light intensity and pressure data recorders. The communication is done using infrared communication with the interface and high-speed USB communication with a PC.

Pocket-size temperature logger (DEFI2-T), a high-precision miniature water temperature recorder for long-term observations.

Pocket-size PAR logger (DEFI2-L), a high-precision miniature light intensity recorder for long-term observations.

Pocket-size pressure logger (DEFI2-DHG & DEFI2-D), a high-precision miniature pressure recorder (depth meter) for long-term observations.

DEFI Interface, the DEFI2 Series common interface.
