Designated use

Digital laboratory for ecology studies provides means for practice in instrumental ecology monitoring with assistance of a notebook/netbook (not included ?).

This set is used in studies of ecology, biology, chemistry, geography and environmental studies. It can be used for individual research and projects of school students.

The laboratory set can be used in the temperature range from 10 to 35 c and humidity up to 80% (at 25 c)

Design and functions

Digital laboratory for ecology studies includes a set of sensors used for taking measurements of ecological parameters of water and aerial environment (e.g., muddiness/concentration of suspended materials, optical density of solutions, concentration of heavy metals, acoustic pollution.)

• Digital sensor of nitrate ions includes electronic unit, ion-selective electrode for no­₃^- and dedicated electrode for measurement comparison
• Digital sensor of chloride ions includes electronic unit, ion-selective electrode for cl ^— and dedicated electrode for measurement comparison
• Digital sensor of water-absorbed oxygen includes a cover with spare membrane, a flask with a solution for filling in the sensor, a storage flask for sensitive solution

Digital sensors are compatible with a computer usb port.

Safety requirements

• While working with digital laboratory for ecology studies the following safety measures must be strictly observed at all times:
• General safety rules set for classrooms designated for studying corresponding subject matters must be adhered to at all times
• Students are admitted to work with the laboratory only after thorough study of its design and functions as well as these safety requirements
• Taking temperature measurements of the solutions heated above 60 c is strictly prohibited
• Excessive tightening of the fixation screw of the optical density sensor may cause deformation of the solution tray and is strictly prohibited
• Avoid water contamination of the sensors and notebook
• Do not open casings of the equipment items and do not subject them to pressure and shock loads
