TR-3804, Ultra Radio Current Data Logger
The TR-3804 monitors standard current signals from 0 to 20mA DC and can be connected to a variety of sensors enabling the logging of a wide range of processes. The logger's design makes it ideal for discreet indoor monitoring in a variety of buildings.
This logger is a component part of the Tinytag Radio data logging system, which automatically sends data from multiple loggers via a receiver for viewing on a PC.
This unit is supplied with an input lead (CAB-3239).
Alternatively you can buy our 2-pin connector plug (ACS-9700) to connect to your own probe/sensor.
This logger is part of a system that requires a receiver and Tinytag Explorer software (ACSR-3030-PK) as optional accessories.
The logger can also be powered from the mains using an optional plug-in power supply (ACS-0005).
If the power supply is interrupted, the logger?s batteries will power the logger and continue recording until the supply is restored.
Please note: this product is only for sale in the EU.
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!
