The Vasthi provides thermal printer which is optional for wireless printing of measurement results from various Vasthi instruments. The Smart printer communicates with the measuring instrument by means of wireless infra-red communication. The Smart printer is suitable for use with the VE5400 series Flue Gas Analyzer.


The high temperature probe made of SS 316 includes a 2.5 meter cable and is intended for measuring the temperature of the combustion air available with different length as per user requirement. This means that you can accurately measure temperatures and combustion efficiency in central heating systems where the combustion air is supplied via a separate channel.
