Check your Exhaust Temperatures with a Zycos Diesel-Engine Pyrometer SHIP engineers know how important it is to have a close check on how each cylinder of the Diesel Engines is fune- tioning. Tycos Pyrometers for Exhaust Temperatures are specially designed to stand ship conditions and give the en- gineer the information he wants, A Tycos Diesel-Engine Pyrometer with a thermocouple in each exhaust port dis- charge line and a 6-point or 12-point switch tells at a glance how each cylinder is behaving. The engineer has an immediate check on cylinder lubrication, cooling water circulation, combustion and valve opera- tion. He knows if he is using too much or too little fuel oil and can check on the condition of pistons and rings. All this is valuable information .. . information the engineer needs and that a Tycos Pyrometer will give. Our en- gineers will be glad to tell you more about the application.
