 That one looks good Hank, seen that one before.  Just a bit pricey.  I ws kind of hoping to keep the cost under £100 as its only a backup.

 Are you looking for a sensor that you can interface to a microprocessor, or an all-in-one monitor that contains both the sensor and display?

 Hi All,
Im going to get another CO2 monitor, as a backup.  I have decent, properly calibrated one, so i dont want to break the bank with this one.
Anyone got any ideas for a reasonably priced backup? It needs to go up to at least 1% really.
What are other people using?Thanksjames
