Metal Samples’ new compact MS2800E Corr Velox ER Transmitter measures all types of electrical resistance (ER) corrosion probes. The ultra high-resolution, 20-bit measurement provides faster response, obtaining corrosion rates in hours instead of days. The transmitter can be remote or direct-mounted (shown).

The transmitter is available in a weather-proof (IP66) stainless steel enclosure designed for applications which do not permit aluminum enclosures (such as offshore environments or Zone 0 hazardous areas). Alternatively, a weather-proof (IP66) and explosion proof cast aluminum enclosure is also available.
