TSI CA-Calc Combustion Analyzer sensor replacement
I recently obtained a TSI CA-Calc 6130 combustion analyzer at a low price, knowing it was discontinued and that O2 and CO sensors are not available from TSI. The attached photo shows the 3-pin CO sensor removed. There is no O2 sensor. It is 2-pin, with pins diametrically opposed. Should be about 1" diameter, maybe with ribs on the perimeter. Any ideas on sources for these 2 items?
