Manta F35
Eureka has fitted its highly successful Manta+35 Water-QualityMultiprobe with a copper-filled, silicone “nose cone” that covers all of the exposed sensors except the critical measurement surfaces.A central wiper keeps those measurement surfaces clean, meaning that you get better data and minimal clean-up.
 
Water-Quality Monitors
Eureka’s MantaTM Multiparameter Water-Quality Multiprobes have been workhorses in the field for over 15 years. Their reliability, data integrity, and lifetime cost are the best in the professional class of multiprobes. But even with innovations like the central wiper and consumable copper-gauze kits, they could not completely conquer a multiprobe’s worst enemy: sensor fouling.

Until now. Gone are the days of measurement surfaces affected by foulants, and endlessly scraping algae, silt, and barnacles from the sensors. The problem is the algae, fungi, bacterial slimes, barnacles, silts, etc. encountered by your multiprobe during logging runs. Not only do they degrade data and increase maintenance, but they can ruin sensors. The solution requires sensors whose measurement surfaces are in the same plane, a wiper with the appropriate brush material, and an easily removed, disposable “nose cone” that covers the exposed sensor surfaces and uses copper to keep biota from attaching to the sensors.

The F35’s unique silicone “nose cone” fits snugly over the sensors to protect the sensor bodies and the active sensor surfaces. The nose cone is easily removed should it become damaged, or when you are doing sensor maintenance (such as changing an ISE tip).

A copper-less nose cone is available, as is a silver-impregnated model. And note that the nose cone has the additional benefit of reducing the volume of solutions needed for proper calibration. The nose cone works in fresh and salt waters, for biological and non-biological foulants.
