Feedback Datalogger kits compared
| Kit | RH probes | Hole liners |
| FBSK5.1 – Starter Kit | 1 x Hygro-i2 | Not included |
| FBZK5.1 – EZ Kit | 5 x Hygro-i2 | Included |
Both include the DL-RHTX datalogger, the interface cable, and tripod and wall mounting. The EZ Kit is the one that can run a compliant ASTM F2170 test out of the box on a small floor; the Starter Kit is a single-point logging setup you add probes to.

Frequently asked questions
Is this enough for an ASTM F2170 test?
For a floor up to about 300 m², yes – five probes covers the three locations required for the first 100 m² plus two more. Larger floors need additional probes and hole liners, one liner per test hole.
Why five probes rather than one?
Because all test locations must equilibrate at the same time. Moving a single probe between holes over several days does not produce a compliant test and stretches out the programme.
