Sensitive Research Instrument ESH 30 kV Electrostatic Voltmeter

Description

Sensitive Research Instrument ESH 30 kV Electrostatic Voltmeter
This meter is good condition.
There are three ranges on the meter. The range is selected by sliding the knob on the back in our out.
Photos show the knob all the way in for the lowest voltage range and all the way out for the highest range.
I used a Thermo Keytek Minizap to check the meter.
One photo shows the Keytek set to 2.5 kV and the meter reading on the low range.
Another photo shows the Keytek set to 8 kV and the meter reading on the mid range.
Another photo shows the Keytek set to 15 kV and the meter reading on high range.
The accuracy looks pretty good.
I'm an electrical engineer and getting ready to retire so I'm selling the electronic test equipment and standards I've acquired over
the years.
Auction is for the Sensitive Research Instrument ESH Electrostatic Voltmeter only.
The Thermo Keytek ESD simulator is not included.
