Anti-fouling, corrosion-resistant sensing packages for effluent that destroys standard sensors — at a cost well below premium international brands.

Background

Industrial facilities in Mexico discharge high-concentration, corrosive wastewater where standard sensors fail within weeks — fouled optics, corroded housings, drifted readings.

Challenge

The effluent features high suspended solids, oils and aggressive chemistry (strong acid/alkali and high salinity), requiring sensors with wide measuring ranges, anti-fouling designs and chemical-resistant materials — without the premium pricing of top international brands.

Solution

Sinno supplied a customized package: corrosion-resistant pH/ORP sensors, high-range suspended solids sensors and COD (UV254) sensors, featuring chemically resistant wetted materials (PTFE/PP/316L options) with automatic air-jet cleaning and replaceable probe caps. All units ship with individual calibration certificates.

Results

• Stable operation in media where previous sensors failed quickly
• Maintenance intervals significantly extended
• Reading drift kept within verification limits across service periods
• Deployed at multiple monitoring points, with repeat orders from satisfied customers
