Since the start of its activities 55 years ago, a significant part of PONSEL R&D budget has been dedicated to the continuous improvement of its sensors offer in order to meet the needs of a wide spectrum of application fields : laboratories, industrial processes, waste or drinking water treatment plants, natural surface or underground waters, fish farming, and so on.
As this is only a part of our sensors range, don’t hesitate to contact-us for specific needs |

pH PONSEL probe
Universel pH probe on the total range : 0 to 14 pH.
The probe is composed of :
· One "glass electrode" formed by a very thin bulb of glass sensitive to the pH and welded with the extrimity of a crystal tube. The electric resistance of this probe is about 10 000 Mégahoms.
A removable polyethylene strainer protects the pH glass.
· One "reference electrode" (type Ag/AgCl) with plasticized electrolyte saturated with KCL "PLASTOGEL"®. |

ORP probe
The sensor is composed of :
- A "Platinum electrode" made of a Platinum thread welded to the extremity of a crystal tube. A removable polyethylene strainer protects the activate part of the electrode.
- A "reference electrode" Ag/AgCl type with an electrolyte coated with plastic saturated with KCI "PLASTOGEL"®
The "PLASTOGEL"® electrolyte is directly in contact with the environment without capillary or porous interposition. There is no risk of reference blocking or defusing. |

Suspended Solid MES probe
The MES PONSEL probe is an optical sensor based on the Infra-Red optical absorption allowing to obtain a direct reading in g/l.
It exists a version with an automatic cleaning system (with the aid of a scraping piston).

Turbidity probe
Optical sensor based on the same principle than the Suspended Solid probe (MES PONSEL probe), this Turbidity probe allows to follow Turbidity of a water in mg/l or NTU.
It exists a version with an automatic cleaning system (with a scraping piston).

Nephelometric Turbidity probe
The Nephelometric Turbidity PONSEL sensor uses 2 signals (90 and 180°) which are traited by ratiometry and the transmitted light (180°C) is the reference.
Variations of the transmitted and diffused (90°) lights are the same, measurements are independents from the fluctuations of the emissive source of light and the colour of the water. |
