#145 - Nova Analyzers from the Field – Episode 1

Intro - We frequently see old Nova equipment still in use all over the world. It’s amazing how long some pieces of sensitive analytical equipment can last in the right application. Every once in a while, I will try to post a picture and a short blurb about one of these older pieces that crosses our path. Here’s the first one:

We were sent a picture recently of an early model Nova portable analyzer. It is being used in a lab somewhere in Quebec, Canada by a company that manufactures furnaces.

This unit is approximately 27yrs old and is apparently still ticking.

The actual model number of this unit is no longer in circulation. And the serial number is so old that I couldn’t locate the original hand-written production file. However, some of the features of the front panel suggest that it is similar to our current Model 375.

The picture indicates that this instrument will do analysis of oxygen, carbon monoxide, carbon dioxide.

There is an illuminated push-button for ‘CO RANGE’ which probably allows the user to switch between a coarse and fine scale. The reason for this usually has to do with the operation of tuning a boiler or furnace. When the furnace is out of tune, it will produce higher amounts of carbon monoxide. Improving the fuel to air ratio will result in lower CO levels.

The high CO range on the analyzer will allow the technician to ‘see’ the CO analysis during the out-of-tune condition. After the coarse adjustments are made, the technician can switch to the fine CO scale for further tuning.

In the newer models, the ranges are as follows:

0-25.0% Oxygen

0-2000 PPM and 0-4.00% CO - switch selectable

0-20.0% CO2

Here is a link to the current model.
