Portable Multi-Gas Analyzer Transdox 5100C

The Transdox 5100C is the latest portable multi-gas analyzer designed for controlling and monitoring industrial process gas in a wide range of applications. The analyzer is housed in a rugged IP66 Peli-case with eight-hour lithium battery & weighing 7kg, making this a truly portable field instrument.

The analyzer simultaneously measures methane, carbon dioxide & carbon monoxide using precision infra-red detectors, and oxygen using a long-life electrochemical sensor. The sensors are specifically designed and calibrated to avoid any cross interference effects with the background gas. The modular design means virtually any combination of sensors is possible.

Using an internal sample pump, the four gases are analyzed and data-logged simultaneously and just a few minutes are required to get a stable reading. Safety is ensured by the incorporation of a flash back arrestor in the gas measuring circuit.

Incorporating a 7” full colour touch screen interface with soft menu keys and a thermal printer for permanent record keeping the Transdox is easy to operate both in permanent or sampling modes. All data is permanently logged for review at a later date. Data can be downloaded via a USB memory stick and is MS Excel formatted.

The analyzer is supplied with a sampling hose and probe fitted with particle and water traps to ensure only clean gas enters the measurement chamber. Everything required fits neatly inside the Peli-case for convenient operation.
