PurgEye 300 Nano Purge Monitor for Titanium Welding

PurgEye 300 Nano is a compact purge monitor for titanium welding where a constant flow of exhaust purge gas can pass through the instrument. This mains-powered welding oxygen analyser measures residual oxygen from 1,000 to 10 ppm. It suits users who need straightforward low-ppm monitoring without an integral pump, data logging or machine-interlock functions.

Free-flow oxygen monitoring for titanium welding

For titanium pipe, tube, manual TIG and orbital welding, the Nano helps you check oxygen in the argon purge gas against the limit required by your welding procedure. It can also monitor suitable welding enclosures and chambers when the exhaust gas provides the flow required by the instrument.

Select the monitor against your required oxygen limit and measurement accuracy. The Nano’s specified measurement range ends at 10 ppm; it is not a zero-oxygen analyser or a substitute for the acceptance criteria in your qualified welding procedure.

Free-flow sampling: choose the right purge arrangement

PurgEye 300 Nano has no mechanical sampling pump or moving parts. Use it where the purge setup supplies sufficient flowing exhaust gas across the sensor. If the application cannot provide that flow, choose a monitor with an integral sampling pump, such as PurgEye 500 Desk.

Secure leak-tight connectors are provided for weld purge hoses. The optional accessory hand pump and gas sampling probe can be used where appropriate.

Low-maintenance oxygen monitoring

The integrated long-life sensor is designed for low maintenance and less frequent calibration. The monitor has a large alpha-numeric display, shows readings in ppm, and warms up in less than 60 seconds.

It is suitable for manual and orbital welding, welding enclosures, pipe and chamber welding, and applications involving duplex steel, titanium and high-specification stainless steel.

Select the monitor for your application

Confirm that the sampling arrangement can provide the flow required by the instrument instructions. Select from the specified 1,000–10 ppm measurement range; this listing does not claim reliable zero-oxygen measurement. If pumped sampling, data records or machine control are required, compare another model before ordering.

See the PurgEye 500 Desk with integral pump and data logging or the PurgEye 200 handheld monitor. Contact Justram with your purge setup and required oxygen limit.

PurgEye 300 Nano: titanium welding questions

Does the PurgEye 300 Nano draw its own gas sample?

No. The Nano has no integral sampling pump. The purge setup must provide suitable exhaust flow across the sensor. If you need pumped sampling or portable battery operation, compare the PurgEye 200 handheld titanium welding purge monitor.

Can I record oxygen readings or control an orbital welder?

The Nano is intended for reading oxygen levels directly on its display, without data logging or machine interlocks. Tell Justram if your titanium welding procedure requires recorded purge results or equipment integration so we can help select a suitable monitor and accessories.
