Concentration Sensor Probe AO03 AO3 A03 Replacement for AAY80390R 40XV 4OXV 4OXV 4OXV2 Overview This concentration sensor probe is a direct replacement probe designed for detectors requiring the AO03 AO3 A03 style sensor. It restores concentration detection capability in compatible detector units without the need for major modifications. Key benefits Direct compatibility: Built to fit as a replacement for models AAY80390R, 40XV, 4OXV, 4OXV, and 4OXV2, reducing downtime and simplifying inventory management. Easy installation: Probe form factor and connector configuration match common detector housings for straightforward swapin replacement. Reliable measurement: Designed to deliver consistent concentration sensing to maintain detector function and process control. Durable design: Constructed for routine industrial and field use to provide long service life when installed and maintained according to equipment guidelines. Cost effective maintenance: only the probe sensor rather than the entire detector unit to reduce maintenance costs and speed repairs. Function and attributes Function: Senses and reports concentration levels for the host detector. Intended as the sensing element that enables the detector to monitor target concentrations. Compatibility: Replacement for AO03 AO3 A03 type detector probes and compatible with the listed model numbers for direct substitution. Size and fit: Standard probe dimensions for AO03 style detectors to ensure proper mechanical and electrical fit with compatible detector models. Materials and construction: Manufactured with sensorgrade components and protective housing suitable for detector integration. Performance: Provides stable sensing performance when matched with the correct detector electronics and calibration procedures. Practical applications and use scenarios Industrial process monitoring: a failed detector probe in a process control system to resume accurate concentration monitoring and keep production running. Environmental and emissions monitoring: Use as a replacement sensing element in station or portable detectors to maintain compliance monitoring and measurement continuity. Maintenance and service workshop: Stock as a spare part for rapid field repairs on detector fleets that use AO03 style probes and the compatible model list. Installation and maintenance notes Follow the host detector manufacturer installation and calibration procedures after replacement. Verify electrical connections and perform recommended calibration or bump testing to confirm proper operation. Store spare probes in a dry, controlled environment to preserve sensor condition until installation. Compatibility reference Compatible replacement for AAY80390R, 40XV, 4OXV, 4OXV, and 4OXV2 detector probes when an AO03 AO3 A03 style sensor is specified.
