MemoRail Modbus Transmitter Product Highlight

MemoRail Modbus is a low-cost, space-saving, alternative to traditional liquid analyzers.

Compact multi-parameter transmitter for process analysis

MemoRail Modbus is a compact, digital transmitter available with up to 2 sensor inputs. It is designed for use with the SE 740 optical oxygen sensor and Memosens sensors for the measurement of pH, ORP, conductivity, oxygen, and temperature. Up to 32 devices can be operated in parallel using Modbus RTU. Device address, link parameters, and data rate are selectable.
