I know this has come up 100 times but they have released new models and I need some help trying to pick one. I posted in commercial forum because thats what I work on and it would get some attention.
So.... whats your pick for working on small building boilers/larger resi boilers? Testo 320 is great but discontinued. Anyone try the 300? Or can the bacharach insight plus handle larger boilers
Very robust, can customize what sensors you need, fastest pump speed that Im aware of, so it responds quickly to burner adjustments etc... And accommodates up to 6 sensors
But I have a local vendor that can calibrate locally, and offer a loaner if mine needs to go in.
That said, the biggest issue is down time.
The biggest difference between a
Residential analyzer and a Commercial one is pump speed, and sensor customizability.
If all you need to do is basic O2, CO, Stack temp and the normal calculated info like CO2, and efficiency- just about any analyzer will do for residential or commercial.
If you need to measure NOx, SO2, etc... you need a commercial model.
I personally have used Bacharach, E-Instuments, Ecom, and Testo analyzers.
I like Ecom the most, but the others listed were also good.
If its between Testo and Bacharach, Id go with the Bacharach for field replaceable sensors, and it runs off of standard batteries, which for me I like.
The PCA-400 probe diameter is the same as the Testo-330 and about the only thing I like about the Testo is the adapter with the plastic cap, dont have wear globes to remove it from the stack.
There is not better place for the working men than the union! 100% UA the only HVAC union!
I love using my Testo 300, it has all the functionality needed as well as ease to send emails instantly with reports. It's pretty easy to use as well and seems pretty rugged, the touch screen is a nice feature as well.
