Real time Sensors for Lakes and Coastal sea waters
- C4E Conductivity sensor
Aqualabo - France
- The C4E sensor offers the following advantages:
• Low operating costs due to reduced maintenance work (no electrolyte changes)
• Greater calibration intervals due to low drift behaviour
• No polarization voltage required • High measuring accuracy, even for low concentrations • Rapid response times
• No minimum inflow (no oxygen consumption)
The sensor features excellent interference immunity thanks to the integrated preamplifier and digital signal processing. The measured value for conductivity is automatically compensated with the temperature and transferred without interference to the connected display unit and controller via a digital interface.
Applications
The compact and robust DELRIN sensor is particularly well suited to the following typical areas of application:
• Industrial and municipal sewage treatment plants
• Wastewater management (nitrification and de-nitrification)*
• Surface water monitoring • Drinking water monitoring

- PONSEL pH digital sensor PHEHT
Aqualabo - France
- The combined sensor PHEHT is based on a principle of measure of difference of potential between a reference electrode (Ag/AgCl) and an electrode of measure (Special pH glass for the measure of pH, and a ring of platinum for the ORP measurement).
The returned measure is given for a temperature of 25 °.
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.
Applications
The compact and robust sensor is particularly well suited to the following typical areas of application: • Industrial and municipal sewage treatment plants
