TGRF-4602, 4-Channel Temperature/Humidity Radio Data Logger
Housed in a rugged waterproof (IP67) case, this self-contained radio logger unit monitors 2 temperature channels and 2 humidity channels simultaneously.
The two supplied coated temperature/humidity sensors offer good resistance to moisture and condensation.
The probes can be inserted into hard to reach areas, such as air conditioning vents and wall cavities.
Typical applications:
- Warehouses and storage
- Air conditioning
- Laboratories
- Building performance and evaluation
This data logger is suitable for outdoor, industrial and warehousing applications.
The unit will typically run for 12 months on its 2 AA alkaline batteries. (The 12 months operation is quoted for a typical 10 minute logging interval in a network with max. 25 radio loggers and at max. 25°C operational temperature.)
If required the unit can also be powered by an optional mains power supply.
The unit is able to transmit logged data to another logger or a receiver or to store data locally in the event of radio contact being temporarily lost.
The data logger has got a status LED:
+ LED off: logger is off
+ green every 4 sec.: everything is o. k.
+ red every 4 sec.: not meshed or battery low or alarm indication
The external temperature/humidity probe PBRF-8001 and the sensor extension cable CAB-0034 are supplied with the Logger.
Please note: This article is only one component of the Tinytag Radio Logger System.
For proper operation minimum one radio data logger and one Tinytag radio receiver with accompanying software are necessary!
