Intellical™ MTC101 is a digital combination oxidation reduction potential (ORP/RedOx) electrode with built-in temperature sensor. MTC101 has low maintenance needs thanks to a non-refillable gel-filled single open reference junction. This Rugged MTC101 version is built with a stainless steel body ensuring sufficient weight to the probe for an easy outside handling, the Metal Platinum sensing part is protected by a shroud, and the connection is ensured by strong and visible yellow coloured cable onto which you can clip depth markers (optional accessories), making the MTC101 rugged models specially designed for field use. MTC101 Rugged is available with a 5, 10, 15, or 30 meters cable. The MTC101 Rugged is ideal for measuring ORP/RedOx absolute mV values in all types of external environment such as river, surface and ground waters, ponds, lakes, sea, wastewater plant, source water, drinking water reservoir for water quality, environmental and treatment process purposes.
