so2 Monitor for Very High Voltages

so2 Monitor for Very High Voltages

This monitor IC features a very wide input voltage range, high accuracy of transfer ratio, small size, low component count, low power consumption, ease of use, and low cost. Offline, battery and portable applications can be served equally well due to the wide input voltage range and the low quiescent current of the HV7800.

  • Development of an SO2 monitor for mobile sources

    This leads to another important requirement, quick response, for the monitor. The instrument achieves high sensitivity by making use of the very strong 802 absorption band near 3000 A while employing a multiple-pass optical system in the sample cell to obtain a long absorption path in a small volume.
