Product Specifications

Environmental Measuring Systems Brno - Datalogger Minikin

   
Minikin is a small datalogger with built-in sensors for the measurement of environmental parameters (T, TH, RT, QT, TT) or for connection of one external sensor (TV, TP). It is attended for long-term monitoring.

The datalogger case is watertight, made from stainless steel and high-density polyethylene. The humidity sensor has sintered stainless steel filter to protect it against splashing.

The non-volatile data memory can store typically 25,000 measured values what is enough for 16 months or the measurement of two variables in hourly intervals. According to measuring mode, the oldest data in the memory can be overwritten with the newest ones or the measurement stops when the memory is full.

The long lasting Lithium-ion battery assures one year of measurement in 10-second interval or six years when one measurement per hour is performed.
