AQUASOL OX-100X Oxygen Monitor Pro Industrial Process Sensor

The AQUASOL PRO OX-100 Oxygen Monitor is a handheld digital sensor designed for precise O2 readings in industrial processes, including welding purge operations, with a built‑in pump that draws a sample for rapid measurement. Powered by a single 9V NiMH battery, it delivers up to about 2 hours of continuous operation and stores data with logging at 15‑second intervals, exportable to Microsoft Excel or plain text. The unit uses an electrochemical oxygen sensor and reports 0.00‑21.0% O2 by volume with 0.01% resolution. Calibration uses a two-point method: CAL HI from ambient air (20.9% O2) and CAL LO with 99.999% Argon; recommended calibration period is upon sensor replacement. Operating temp 0‑50 C; storage 3‑20 C; humidity 0‑95% RH non-condensing. Sample flow up to 1.0 LPM; response time T90 < 15 seconds; USB Type B PC connection. Kit dimensions approximately 11 x 9 x 4.2 inches and weight around 4 lb; made in the USA at an ISO-certified factory.
