Analysers

     
 
High quality and reliable panel mounted and portable analysers primarily designed for Oxygen and Carbon Dioxide measurement but may be used for other gases with suitable sensors. The 481 and 482 analysers are designed to measure and display either Oxygen or Carbon Dioxide and are intended for panel mounting in a standard DIN cut-out.

As well as providing an analog output signal corresponding to the gas concentration, the analysers have the facility for operator entry of up to 6 high and low set points to enable relay control under the direction of optically coupled external select inputs.

Measured gas values and set point examination/change are indicated on the integral back lit LCD.

Using appropriate calibration gases, zero and span may be adjusted from the front panel and the examination/change of set points is made using the 4 buttons below the display.


 
         
  Model 481 Carbon Dioxide

Carbon Dioxide is measured in the 481 for the range 0 to 10% using the principle of infra red adsorption. This physical method of measurement offers high selectivity, good accuracy and a fast response.

      Model 482 Oxygen Analyser

 Oxygen is measured in the 482 for the range 0 to 21 % using a galvanic cell with a typical life of 5 years. The operation of the galvanic cell is similar to a regular primary cell battery in that
a voltage is produced by an electrochemical reaction. In this case, however, the reaction is regulated by the presence of Oxygen.
