Rapidox 1100 Argon Analyser
Product Information
The Rapidox 1100-G argon (Ar) gas analyser is the company’s most cost-effective and versatile argon gas analyser fitted with a Thermal Conductivity gas Detector.
The Thermal Conductivity Detector (TCD) is a state-of-the art German engineered sensor and is the most common and preferred solution for argon measurement providing fast and accurate gas analysis over the range 0% to 100% Ar in simple binary gas systems, where the argon is mixed with another background gas or air/nitrogen. It is particularly suitable for aggressive industrial applications as long as the sample gas is filtered for dust and particles and is non-condensing. The sensor has a 50°C heated sensor chamber to overcome measurement drift caused by ambient temperature changes. A common application is measuring the composition of Ar/H2 welding gas mixtures.

TCD sensors (also known as Katharometers) are highly suitable for measuring gases that have a thermal conductivity value significantly different to air, as long as the gas mixture is simple. The sensor can be factory calibrated for a specific gas mixture such as argon in hydrogen for example.
Please note that TCD sensors are not very reliable in complex gas mixtures where there are several gases with different thermal properties. The TCD measurement principle is an indirect measurement of the overall thermal conductivity of a gas and this is interpreted as a composition based on a factory calibration. The standard R1100-J is available in various ranges 0-5%, 0-10% 0-50% 0-80% and 0-100% Ar selected at the time of ordering. The standard range however is 0-100% in a background of air/nitrogen, with a choice of gas fittings on the front or rear of the instrument. Upgrades to Swagelok fittings (1/4” or 6mm) are available at the time of order. Each version is available with a choice of internal electric sample pump or vacuum ejector pump.
Special variations of the R1100-J model include:
1) A stainless steel IP54 instrument version with 316 stainless steel instrument case and sealed gasket joints, designed primarily for the food and pharma industries.
2) A 4U bezel mounted version compatible with 19” rack mount systems.
Finally, the Rapidox 1100 argon analyser with EMC Directive 2004 / 108 / EC. UL/ETL Certification Number: UL-61010-1.
