The MultiExact 4100 is a highly adaptable multi-gas analyzer

The MultiExact 4100 is a high-performance multi-gas analyzer designed to provide up to four simultaneous gas stream measurements including: oxygen (O2), carbon dioxide (CO2), carbon monoxide (CO), nitrous oxide (N2O), methane (CH4) and moisture (H2O).

Up to four simultaneous gas stream measurements

Specifically designed to address the needs of industrial and medical gas manufacturers, the MultiExact 4100 can provide up to four simultaneous gas stream measurements including: O2 (trace, control, and purity), CO2, CO (% and trace), N2O, and CH4 (trace).

It can be fitted with a wide range of sensing technologies – Paramagnetic, Zirconia, Gas Filter Correlation (Gfx), Infrared, and Aluminum Oxide. These proven, digital sensors not only provide highly accurate measurements but also offer operational flexibility in a range of industries and applications.

The non-depleting, high-stability sensing technologies help extend maintenance intervals while intelligent functionality such as independent auto-calibration helps to deliver operational efficiencies over a long product life.

High reliability and unrivalled performance

With a strong combination of features and benefits, the MultiExact 4100 is a highly adaptable analysis solution that meets a range of needs.
It uses a wide range of Servomex’s proven, reliable and accurate sensing technologies to provide up to four simultaneous gas stream measurements, meeting the challenges faced by industrial and medical gas manufacturers. With flexible analysis solutions capable of meeting specific process monitoring needs, the MultiExact 4100 delivers precise, stable results at every point of the ASU process. The versatile MultiExact 4100 can be customized to meet your exact requirements, giving you the accuracy you need, without compromise.

The next-generation solution

The MultiExact 4100 shows how sophisticated modern gas analyzers can be, with built-in support for the new Servomex AquaXact 1688 moisture sensor, up to 32 relays/alarms and four analog inputs for integrating information from external sensors such as temperature, pressure or concentration information from another gas sensor. In addition, analog and digital communications include the traditional 0-10V DC, 4-20mA, RS232 and RS485 outputs, while also providing optional advanced digital protocols, including Serial Modbus and PROFIBUS, with Ethernet (Modbus TCP/IP) to follow. In addition to its considerable monitoring capabilities, the MultiExact 4100 also provides engineer-friendly interaction through a high-brightness color touchscreen display and
an intuitive, icon-driven user interface. It combines all the reliability of Servomex’s familiar technology range with the flexibility, ease of use and range of intelligent digital options that the modern IG market demands.

Simple maintenance and reduced ongoing costs

The efficient, next-generation design of the MultiExact 4100 keeps maintenance requirements at a minimum. Servomex’s non-depleting, low-drift technologies are easy to set up and install, especially with the new touchscreen display and easy to use interface. With ongoing costs for sensor replacement eliminated, and recalibration only needed at extended intervals – plus independent auto calibration – the cost of ownership across the product lifetime is kept extremely low.
