Gas Analyser for Oxygen Analysis Down to ppm
Simple and Accurate Industrial Stack Gas Flow Measurement
The new, multifunctional MF Plus Manometer from MRU GmbH offers a simple, yet effi cient method of measuring traverse point volumetric fl ow rates in industrial stacks, compliant to European Standard EN16911-1 and ISO 10780 and USEPA 40CFR Part 60, Method 2.
The gas technology manufacturer Witt has unveiled a new development that can measure trace oxygen levels. The gas analyser PA 7.0 now enables reliable analysis in the ppm (parts per million) range.
In many industrial processes, even the smallest amounts of oxygen can cause major problems, such as undesired oxidation. Even trace quantities of oxygen in gaseous media are now detected by the PA gas analyser. This is made possible by a highly sensitive zirconium cell, now available as an option. Witt has thereby extended the PA product series into a totally new dimension of gas analysis. While the classic PA with chemical sensor measures in increments of 0.1 %, the new zirconium version detects in the ppm range. The accuracy of the measurements is +/- 5% relative to the measured value.
All measured values are stored, and can downloaded via a standard interface for further processing. Weighing just under six kilos, the PA is only 186 x 285 x 270 mm (HxWxD) in size. It is protected by its sturdy stainless steel housing.
Witt’s new PA version forms part of an extensive product portfolio comprising mobile and stationary systems for countless gas applications – especially in food packaging, medical applications, metalworking, glass production as well as in numerous industrial processes requiring a high degree of precision.

Available for CLD60, CLD Supreme-Line and the upcoming CLD series from Eco Physics, the “GUI - Graphical User Interface” controls the instrument set-up, calibration, measurement, data management and remote operation. GUI is navigated via the 8-inch touchscreen at HD-resolution. The platform displays and manages a user optimised presentation, instrument setup, security, timer control (measurement, calibration, linearisation sequences), data logging, data storage, diagnostics and signal in-/outputs (Analogue In/Out, RS-232 Serial connector, Digital In/Out, LAN, WiFi). The CLD dashboard can display your values individually, for instance by a simple screen, detailed view, or graphical curve. Each screen can be altered within, for instance by fading in additional data or fading out information that you may not require for the moment.

GUI also includes the settings for remote control and remote operation by RDC (Remote Desktop Control) and VNC (Virtual Network Computing). Both features possess recommended security settings, which can be individually altered. It is possible to set up 4 user logins, which can be protected by a password on demand. The (1) Standard User has, beyond his Login, no additional protection and is able to operate the unit without changing the parameters. The (2) Extended User is additionally able to defi ne and execute a calibration. (3) Maintenance covers all previous features, including the instrument’s setup and access to the instrument parameters. The (4) System Operator is restriction free and also manages the security settings of the instrument. He is able to individually customise the access authorisation for each user.
While operating your instrument, “GUI” offers a quick “Help” function, which will offer direct assistance for your currently opened window, as well as a link to the online manual of your instrument. If required, “Help” will guide you step by step through each function of the instrument, beginning from the instrument’s set-up to the more complex operation features.
With the implementation of “GUI” Eco Physics takes the individual, customer friendly operation of CLD-analysers to a whole new level.

NEW: “GUI - Graphical User Interface” Available for CLD-Analysers
This unit can perform simultaneous measurements of differential and barometric pressure and temperature, whilst adjusting to conditions of wet or dry gas. It will also work out current and average data, either with ‘start-stop’, or a pre-set average time, of up to 10 minutes and calculate absolute or static pressure in the stack, whilst adjusting to compensate for ambient barometric pressure. MF Plus is also capable of automatically calculating point average data for compliance to EN 15259, whilst its intuitive menu allows you to make traverse point fl ow rate measurements in ducts, stacks and pipes in accordance with EN 16911. MF Plus can calculate up to 100 traverse point measurements in a single stack, can perform swirl correction in case of cyclonic fl ow, calculation of nozzle and indication of correct fl ow for isokinetic sampling of dust, according to EN 13284- 1 and has a datalogger of velocity and fl ow for long term measurement, with graphic on display and export on CSV fi le.
This versatile instrument allows the user to manually input the stack’s cross sectional parameters, such as size, diameter and number of traverse points within the grid. You can also input gas data composition for gas density calculations to
