Produkteinführung

This single-gas analyzer combines a protected benchtop indicator, one visible variable-area flowmeter and a fine sample-flow control in a portable enclosure. Oxygen-rich gas enters through a front quick connection, passes through a short clean sample path and reaches a dedicated percent-oxygen sensing cell before controlled venting. The display shows the stabilized oxygen concentration directly, while four fixed keys provide access to calibration, hold, range and stored-result functions. A removable sensor-service cover, calibration port, folding top handle and stable feet support routine checks around oxygen generation, filling and distribution equipment without adding the multiple channels of a general gas-quality test case.

Key Features

Dedicated percent-oxygen measurement presents oxygen purity directly rather than combining unrelated particle, moisture or oil channels.

One clear variable-area flowmeter and one fine adjustment knob make the sample condition visible and repeatable during stabilization.

Short low-volume wetted path and a single inlet connection help reduce purge time and trapped ambient air between sampling points.

Four-button interface provides straightforward calibration, display hold, range selection and result storage without a complex multi-screen panel.

Separate protected calibration access supports span checks without exposing the main sample fitting to unnecessary handling.

Compact enclosure, folding handle and four anti-slip feet allow stable benchtop use and easy movement between oxygen outlets.

Kunden Produktbedenken

Reliable oxygen-purity measurement depends on a leak-tight purged sample path, stable flow and pressure, a sensing principle compatible with the background gas and calibration that represents the actual measurement condition.

Ambient air trapped in the tube can make an oxygen-rich sample read low and stabilize slowly.Keep the sample line short, make a leak-tight connection and purge the complete wetted path at the selected flow before recording the stable value.

Excess inlet pressure or flow can disturb the sensing cell and bias the result.Reduce the source pressure appropriately, adjust the single flow-control knob gradually and keep the flowmeter within the configured operating band.

A sensor principle suitable for one background gas may be affected by another gas or by reactive contaminants.Select the percent-oxygen cell for the expected gas matrix and review possible cross-interference, condensation and hydrocarbon exposure before sampling.

Calibration uncertainty can be mistaken for a change in oxygen purity.Use a suitable traceable span gas, match the calibration flow and pressure to the measurement condition and record the calibration date with the test result.
