    K33 ICB 10% CO2 Sensor

    Very helpful customer service

    I knew basically what I required but didn’t know all the options, so I called and got excellent customer service. They showed me where on the website the items were that would fit my application, and the items came within 3 days of ordering. I would definitely order from them again.

    I have not yet had the time to put everything together, but will rate the sensor and pump once I do.
