Long-Term (LT) Electret
Long-Term Electrets are intended for long-term radon measurements lasting from three months to over a year. They are shipped with 700+ volts to ensure numerous deployments, and can be readily analyzed at your home office or laboratory.
The long-term electret contains a charged disk that serves as both the source for ion collection and as the integrating ion sensor. Negative ions produced inside an attached chamber (sold separately) are collected on the positively charged electret, causing a reduction of its surface charge.
