Logger version 2-D electro-magnetic current meter
INFINITY-EM

Logger version 2-D electro-magnetic current meter INFINITY-EM AEM-USB

Infinity EM is an electromagnetic current meter logger. The instrument provides high accurate 2-D current measurements even at low scattering conditions, where ADVs (Acoustic Doppler Velocimeter) do not perform well.
The measurement range goes from 0 to ± 500 cm s-1. The instrument design is compact (1.0 kg in air) and allows for current velocity measurements virtually anywhere.

Logger version 2-D electromagnetic current meter for deep ocean
INFINITY-Deep

Logger version 2-D electromagnetic current meter for deep ocean INFINITY-Deep AEMD-USB

INFINITY-Deep is an electromagnetic current meter logger for deep ocean. It is hard to accurately measure deep water currents using acoustic doppler current meters because suspended particles are almost inexistent. INFINITY-Deep measures 2-D current velocity using electromagnetic sensor. Therefore, even if the suspended particles do not exist around the sensor, it can provide accurate data. Compared to INFINITY-EM, the instrument has a depth and a tilt sensors to monitor its mooring condition. The depth rating is 6,000 m, and its battery capacity is doubled.

Water pressure principle logger version wave height meter
INFINITY-WH

Water pressure principle logger version wave height meter INFINITY-WH

INFINITY-WH is provided with a large capacity storage memory that allows for 0.1 s sampling, and for wave height observations from short to long period waves. The instrument can perform continuous observations for over a month (sampling for 20 min at 0.1 s interval per 1 hour burst - about 12,000 samples.)

Logger version conductivity and temperature sensor
INFINITY-CT

Logger version conductivity and temperature sensor INFINITY-CT

INFINITY-CT is temperature and conductivity logger. The conductivity sensor has a conductivity cell designed using 7 electrodes. The compact-sized instrument (Φ54 mm x 255 mm, 0.7 kg in air) can be deployed and integrated in a variety of platforms. The instrument depth rating is 2,000 m.

Logger version conductivity and temperature sensor with wiper INFINITY-CTW
INFINITY-CTW

Logger version conductivity and temperature sensor with wiper

INFINITY-CTW is a temperature and conductivity logger with wiper for long-term measurements. The instrument’s mechanical wiper periodically cleans the sensing surface of the 7-electrode conductivity cell to keep the initial accuracy, avoiding biofouling without chemical materials and frequent maintenance. INFINITY-CTW allows for accurate and stable salinity measurements for several months without cleaning maintenance. INFINITY-CTW performance was evaluated and reported by Alliance for Coastal Technologies, ACT code: VS09-06

Logger version conductivity and temperature sensor with wiper
INFINITY-CLW

Logger version conductivity and temperature sensor with wiper INFINITY-CLW

INFINITY-CLW is a chlorophyll and turbidity logger with wiper for long-term measurements. The light sources (LEDs) of chlorophyll and turbidity sensors are highly stable, minimizing the change over time. The instrument has a mechanical wiper that keeps the optical windows free from biofouling.
The turbidity sensor has a good correlation with SS (Suspended Solid) over the range. INFINITY-CLW provides highly accurate and stable chlorophyll and turbidity data during long-term deployments.

Dual range turbidity logger with wiper
INFINITY-Turbi ATU75W2-USB

Dual range turbidity logger with wiper INFINITY-Turbi ATU75W2-USB

INFINITY-Turbi is a dual range turbidity logger with wiper for long-term turbidity measurements. The dual turbidity range covers low (0 to 1,000 FTU) and high (0 to 100,000 ppm) turbidity conditions.
The instrument provides highly accurate turbidity measurements in normal to muddy water. INFINITY-Turbi mechanical wiper keeps the optical window clean from biofouling during long-term observations. The instrument has additional temperature and depth sensors as standard, and can be deployed in a variety of conditions.

Turbidity and temperature sensor for the deep ocean ATUD USB

Turbidity and temperature sensor for the deep ocean ATUD USB

ATUD-USB is an autonomously deployable data logger for long-term turbidity and temperature measurements in deep water.
The temperature and turbidity sensors are highly stable, allowing for accurate data for long periods of time. Turbidity is detected through infrared backscattering and the sensor output has a good correlation with SS (Suspended Solid) over the range.
