The WS Oxy I is a hand-held, battery-operated oxygen analyzer. The measuring range varies from 1000 ppm to 10 ppm. The device has a maintenance-free zirconium cell with extended operating life. It is supplemented with an innovative display that represents operating state in color. This ”traffic light system” provides the operator with a high level of comfort: since the operation state can be shown in colors visually, there is no need to read the exact values. The software and the operation method of the device are identical to the WS Oxy II. Furthermore, it has a loud integrated buzzer.
The reports of the device (buzzer, colors, flashing of the readings, etc.) are very simple and user-programmable.

The device is offered in different versions. Standard device includes analyzer, transport box, a plug-in power supply unit, the manuals in German and English, as well as the calibration certificate. In addition, a car charger cable can be acquired (cigarette lighter).

The Premium version has multiple outputs for documentation, PC connection, Bluetooth, 0-5 VDC analog and an RS 232-cable for a printer.
