PRECISION SMART SENSING FOR ANY AIR READING
The Phoenix DryTAG RH 2 brings high‑accuracy temperature and humidity tracking to any dehumidifier—no matter the brand, age, or model. Capturing precise readings every 15 minutes, it stores data onboard until it syncs with a DryHUB+ or a technician’s mobile device. Whether attached to a dehumidifier or used as a standalone thermohygrometer, DryTAG RH 2 delivers the environmental data technicians need to make informed drying decisions.
Designed for real‑world restoration challenges, the DryTAG RH 2 also functions as a long‑range asset beacon, helping you keep track of your equipment across job sites, warehouses, and trucks. With a 10‑year battery, universal compatibility, and smart status detection, it’s one of the most versatile tools in the DryLINK® ecosystem.

WHY IT MATTERS — PRECISION YOU CAN TRUST, AUTOMATION YOU CAN COUNT ON
Temperature and humidity readings are critical for verifying drying progress, but collecting them manually wastes time and introduces inconsistencies. DryTAG RH 2 eliminates both by automatically capturing highly accurate data—even in challenging environments where readings can fluctuate quickly.
Because it works with any brand of dehumidifier, it instantly modernizes older or non‑smart units, giving you job‑hour tracking, run‑time verification, and power‑loss alerts without costly upgrades. Long‑range communication ensures data travels across large structures and dead zones, while onboard memory guarantees no information is lost.
