H2-CNI I2C-E ULTD
High-precision, maintenance-free hydrogen detection
In H2-CNI I2C-E ULTD both, the sensing and reference elements are connected to pins, thereby allowing direct measurement of the balance voltage of the Wheatstone bridge with an external amplifier. Built on a catalytically highly active, siloxane-resistant sensing element and operating on a non-isothermal calorimetric principle, this sensor delivers consistent performance from lab environments to real-world deployment in an extended temperature regime.
