Thermometer hygrometer data logger

code: S3120
Data logger is designed for record of temperature and humidity. 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 communication adapter.

Logger Downloader - free application for data download from Android smartphones and tablet PCThe device includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.

For communication with the PC must be from Optional accessories ordered USB adapter, LAN adapter or COM adapter or start/stop magnet if is needed to control logging the other way than directly from computer.

Features

GSM communicationMain applications of data logger:

  • Food and beverage industry (HACCP)
  • Pharmaceutical industry
  • Horticulture and cultivation of plants
  • HVAC (heating, ventilation, air conditioning, cooling)
  • Building and energy management
  • Research and development
  • Laboratories (GLP)
  • Warehouses
  • Technological processes
  • Museums, archives, galleries

 

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 from the PC)
  • 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 in several ways: at certain time and date programmed from computer, by delivered magnet
  • also special logging mode is enabled, when logging runs only, if some of measured values are out of adjusted alarm limits
  • each data 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

 

Included in delivery:

  • Data logger including the battery
  • Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
  • Quick start manual
  • Free basic Windows software is ready to download at folder Download
