Ultra Stable Surface DC Volt Meter USSVM2
An electrostatic meter, the USSVM2 reads static electricity without contact. It measures voltage on surfaces and can be used to calculate charge density on insulators. It has peak hold and a resolution of 1/10 of a volt on a 20K volt range.
Air Ion Counter Model AIC2
The Air Ion Counter Model AIC2 is a Gerdien condenser meter that measures the number of positive negative ions in air, with USB datalogging.
ADDITIONAL NOTE: Occasionally, when component volume gets low due to supply chain problems caused by the pandemic we may need to ship AIC2s with blue and white displays. Please rest assured that our AIC2 will continue to be the same quality instrument we have been shipping for years with a slightly different display.
