Product Description The AM-ODO-TX is one of the most compact, durable, and user friendly dissolved oxygen sensor on the market. It is an optical sensor that utilizes fluorescence q uenching technology. The AM-ODO-TX is part of the AquaMetrix smart sensor series. The probes in this series are direct output digital sensors with the precision of a controller and the accuracy of our core probes. The AM-ODO-TX can communicate via RS485 or Modbus protocols. This innovative sensor outputs two (2) digital-based analog (4-20 mA) signals that can be set as 2 of 3 options: Percent-saturation, concentration, or temperature. It can connect to the AquaMetrix AM-2300 controller, AM-2252 controller or directly to a PLC. Optical DO sensors are inherently self-referencing, require no warm-up period, do not require constant flow to maintain a stable reading, and are less affected by fouling. The ODO-TX is reliable and reads accurately within 90 seconds of going from dry to wet conditions. The reliability is backed by the factory-programmed 90-point calibration, stored directly on in a memory chip embedded in the membrane cap. The sensor membrane lasts for one to two years and is inexpensive to replace. The intuitive membrane cap Visual Lifecycle Indication (VLI) methodology lets users know when to replace the cap, giving the user comfort in reliable operation. New membrane caps come pre-calibrated, so for maintenance simply install the new cap, and you’re ready to go! When needed, intermittent calibration is simple and can be done on a controller or directly on the probe. This sensor is proven via extensive testing and its core technology helped develop the EPA-approved method that other manufacturers follow.
