Datalogger DL 1/N

• Recording of precipitation values
• Precipitation transmitter with tipping bucket as sensor
• Data storage for precipitation quantity
• Mains independent - battery driven
• Data transfer with memory card or HS 232

Technical Description

The DL1 IN Data logger is designed for the data acquisition and storing of precipitation values, as they are detected by precipitation transmitters with reed contact or active impulse output .
The Precipitation transmitter, order-no. 5.4031.30.006, delivers a signal per 0,1 mm precipitation which is stored with the DL1/N Datalogger.
The stored data can be recalled by the day and indicated on a display.
The data can also be read-out via a memory-card or the serial interface for further processing. Operation is done via 2 buttons and is incomplex.
The unit is powered by four built-in Nicad batteries.
