Are there any instrumental techniques for determining high H₂O₂ concentrations?

What electronic or electrochemical instruments are there to measure up to 2000 ppm of H₂O₂?

You can devise amperometric and polarographic methods for doing hydrogen peroxide determinations. But at concentrations of peroxide that high, it's quicker, cheaper, and more accurate to just titrate your sample with KMnO₄ and be done with it.

5 H₂O₂ + 2 MnO₄^- + 6 H⁺ 5 O₂ + 2 Mn²⁺ + 8 H₂O

See H2O2.com's page on Analytical Methods for several hydrogen peroxide determinations applicable in different concentration ranges.
