Specification :

Data logger for current 0-20mA,
voltage 0-5V and binary signal
Data loggers are designed for record of voltage signal 0-5V (optionally 0-10V) or current signal 0-20mA. At the same time state of binary signal can be recorded. Values are stored to a non volatile electronic memory. Data transfer to the personal computer for further analysis is performed via USB, RS232, GSM or Ethernet interface by means of a proper adapter.
Main applications of data logger:

* Distant places with no electric power
* Long term field measurement
* Research and development
* Laboratories
* Technological processes

Advantages of data logger:

* included traceable calibration certificate from the manufacturer - Comet
* fast data transfer to the PC (full memory for approximately 30s)
* variability of connection to the computer - USB, RS232, Ethernet, GSM modem
* permanent connection to the PC enabled, data is possible to download even during logging
* large data memory 32000 values
* large dual line display with special symbols, switchable
* optional display of minimum and maximum measured values (reset of min/max memory from PC or by magnet)
* dual level alarm is enabled for each channel, alarm is indicated by blinking of the value on the LCD display
* two alarm modes are enabled: instant or with memory (detected alarm is indicated permanently till alarm memory is cleared)
* robust watertight case
* easy installation, locking enabled
* low power consumption from battery, battery life up to 6 years
* indication of remaining battery life, easy replacement of the battery
* logging start/stop is enabled: at certain time and date programmed from computer, by external binary signal or by delivered magnet
* also special logging mode is enabled, when logging runs only, if some of measured values are out of adjusted alarm limits
* input signal is recalculated and displayed in real measured physical units by means of the PC software
* each logger is possible to describe with text of maximum 32 characters
* each channel is possible to describe with text of maximum 16 characters
* password protection is enabled to prevent unauthorized manipulation with logger
