Testo 350 XL Replacement Sensors

The Testo Model 350XL is a tried and true portable combustion analyzer, one of the best of its kind, when it was introduced to the market. Keystone features include interchangeable, calibrated sensors with temperature control; a CO sample dilution system for test range expansion; complete, onboard sample conditioning; and an abundance of opportunities to interface with the entire system. The cells can be easily replaced or exchanged for greater testing flexibility.
