PRODUCT DESCRIPTION
The TH-S41 is a four-channel humidity data logger that monitors four points simultaneously through external Honeywell sensors. Each channel covers 0–100%RH at 0.1%RH resolution, giving one synchronized humidity record across a space.
It suits uniformity mapping and multi-zone storage where separate loggers would drift out of sync; data downloads by USB.
