F501A Portable Oil Vapor Monitor

3 in 1, Oil vapor, dewpoint, pressure measurement

Characteristics

The F501A is a high-precision, wide-range portable instrument. It measures oil vapor concentrations from 0.001 … 5.000 mg/m³ and
simultaneously monitors pressure dewpoint, pressure, and temperature, delivering excellent cost-performance.

Refer to the ISO 8573-1, the F501A features oil vapor and dewpoint class evaluation functions for compressed air, making it an ideal
choice for on-site inspections.

A 7″ touchscreen provides real-time curve display, data recording, and USB export. With 25 GB of onboard storage, users can easily
perform professional data analysis directly in the field.

Automatic background calibration and self-cleaning at shutdown ensure reliable accuracy and extend sensor lifetime. Multi-color LED
indicators, combined with on-screen alarms, clearly display the status of power, measurement environment, sensor, and filter, providing
users with full visibility into system operation.
