Ntron Model OA-1 is the industry benchmark for transportable oxygen analyzers for ultra-pure gas applications. Capable of analyzing PPM levels of oxygen in inert gases, the OA-1 delivers rapid response with high reliability to 1PPM O2.
The compact, lightweight design allows the OA-1 to meet spot check, QA/QC, and process control applications.
The user-friendly, keypad command system and LCD display assure ease of analyzer control. Microprocessor control and large LED display facilitate analyzer operation, data acquisition, and processing. The OA1 has two alarms with independent relays, which may be set and controlled by the operator.
