Digital Static Field Meter / Ion Test Kit

The Desco Digital Static Field Meter indicates surface voltage and polarity on objects. The meter can measure ranges of 0 to ±1.999 kV or 0 to ±19.99 kV at a distance of 1 inch with an accuracy of ±5% of the displayed value.
The Desco Ionization Test Kit allows the Digital Static Field Meter to be used to measure the offset voltage (balance) and charge decay of ionization equipment. The Test Kit also includes a Charger used to place a ±1000V charge on the Conductive Plate, making it possible to also measure the discharge times of air ionization equipment per ANSI/ESD SP3.3 Periodic Verification of Air Ionizers.
The Ionization Test Kit includes the Digital Static Field Meter, providing a highly portable and cost effective means of verifying the performance of a wide variety of ionization equipment.

There are a few UA-camrs show casing high voltage Electrostatic experiments, what can be used to measure 400kV or higher?

I have one of the 19492 models and after zeroing it doesn't seem to work on anything even an statically charged balloon.
