Analysers

LC-450A

Low sub ppm Pumped Oxygen Analyser

Advanced Oxygen Analyser :

The LC-450A from Toray Engineering Co Ltd, is a highly advanced, high performance Zirconia Oxygen Analyser. Toray Engineering have been at the forefront of Zirconia Oxygen Analyser design for over 30 years.

The LC-450A  has very high levels of durability and reliability. It combines this with a desirable set of features, making it ideal for many applications in the electronics as well as process control industries

A Model: 240VAC 

D Model: 24VDC

Product Features

Zirconia ceramic cell: 

Toray Oxygen Analysers determine oxygen concentration by using the conductivity of a Zirconium ceramic cell. Zirconium ceramic cells allow only oxygen ions to pass through at high temperatures. The Instrument uses a reference gas on one side and sample gas on the other. Oxygen ions move from the side with the highest concentration to that with the lowest concentration. This movement of ions generates an Electro Motive Force (EMF) which is measured to determine oxygen content. This process is in accordance with the Nernst Equation.

The LC-450A has a fast response time (T90 within 30 secs) with minimal line lag. Customers value these features highly. Typical Applications are in residual oxygen monitoring for 3D metal printers, semiconductor vacuum deposition systems, baking furnaces and Coating machines.

Unique Sensor technology : 

A key feature of the Toray LC-450A is it’s unique sensor coating resulting in very high reliability and durability.  This allows users to experience much longer sensor life in addition to calibration down time when compared with other solutions. Users can obtain significantly lower lifetime operating costs as a result. The sensor technology also creates a lower sensor resistance which results in extremely reliable, repeatable, accurate and precise readings over time. A feature customers find particularly desirable in an Oxygen Analyser.

The LC-450A is designed to Monitor oxygen with a very wide range from low ppm (1 ppm) up to 100% Volume Oxygen, (Values less than 1 ppm are possible, but aren’t guaranteed, and are considered reference values).

Users find the LC-450A is easy to install in addition to having a wide power supply range of 100-240VAC . A 24VDC Version is also available.
