The PHEH sensor has been designed to perform under hard conditions from pure mountains water with conductivity as low as 20 μS/cm, lakes and rivers (100 – 2000 μS/cm), seawater with conductivities of 50 mS/cm and to wastewater with conductivity higher than 200 mS/cm.

This sensor features a “long life” reference. The Plastogel® PONSEL technology increase the lifetime of the probe the need to refill.

This sensor has been designed also for handheld and in situ applications which have been the most difficult situations for a pH/ORP sensor in term of sensor resistance, quick time response, minimal flow dependence and low power consumption.

Autonomous Platforms (Glider and AUV's) for the acquisition of Marine parameters (Oceanography & Coastal Monitoring)

Alseamar SEAEXPLORER Glider
Alseamar - France
The SEAEXPLORER underwater glider is a powerful autonomous sensing platform designed to collect water column data profiles with very wide spatio-temporal coverage (thousands of km and weeks to months of endurance).

Driven by buoyancy changes, the vehicle silently glides up and down the water column while collecting physical, chemical, biological and/or acoustic data depending on the fitted sensors.

The SEAEXPLORER glider is a very cost-effective solution for data collection as it reduces reliance on large vessels with high daily running costs: no surface supervision boat is required during the mission. The SEAEXPLORER is easy to operate and can be deployed and recovered by reduced crews in coastal waters using small boats.
