Standard measurement ranges are: 0-10ppm, 0-100ppm, 0-1000ppm and a 0-25% range for simple and accurate air calibration.

The Model 1000 is supplied with push button quick disconnect fittings for the sample gas in and exhaust ports. These quick disconnect fittings offer a dual benefit. They allow for rapid point-to-point analysis and when disengaged serves as automatic shut off valves, trapping low levels of oxygen from the previous measurement point. This ensures quick response and recovery times between measurement sites as well as extending the sensor life. This holds true whether the duration between measurement points is minutes or several days.

The advanced patented cellblock design produces fast up and down scale response times and quick front panel access to the oxygen sensor. This allows you to install, replace, or air calibrate in seconds without the use of tools.

You can quickly and accurately calibrate on ambient air (20.9%) due to the excellent linearity throughout the entire range of measurement or use a certified gas standard.
