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?

    Maybe these guys can point you in the right direction.

    Both of those sensors are currently used in the Bacharah Intech. However when you replace the CO sensor it has to be calibrated.
    I may be the only one in the country that does that because we sold most of the TSI analyzers.
