Oven
BOD - Hach measuring system	A measuring device for Biochemical Oxygen Demand(BOD).
Solar Rule	This instrument measures the time of sunrise and sunset, the time of day, angle of the sun and the solar azimuth and daily orbits, the angle of maximum sunstroke one collector and the matching between the solar year and the showing of the clock hour. It consists of three surfaces disposed one above the other, of which one is kept constant, while the two transparent disks are free to rotate independently of each other around the same center.
Anemometer / Wind vane	This instrument is used to measure the speed and direction of the wind. It uses a small fan that rotates due to the air passing through the fins. The rotational speed of the fan is measured by a rotation meter and converted to wind speed by an electronic circuit.
Electronic Thermometers	The electronic thermometers are used for accurate temperature measurement. Changes in temperature cause changes in the resistance of the device. The device measures the resistance and converts it to temperature, which is displayed on the screen.
COD Measuring Device	Device for measuring the chemical oxygen demand (COD).
Compressor	A device that converts engine power into kinetic energy by compressing air.
Recorder--- Stylitis-40	This device can measure direct electrical voltage, frequency and pulse. Using the appropriate sensors it can also measure: wind speed, wind direction and wind turbine power curve, temperature, humidity, pressure, solar radiation, rainfall levels and water velocity.

Reagents & Experiment Containers
Spectrophotometer	The Spectrophotometer is a device that measures the intensity of a selected frequency radiation. The first part of the spectrometer consists of a source of radiation. The second part is what separates the desired wavelength (frequency) of the other generating wavelengths the source produces, thus allowing third party "monochromatic" radiation. The third part is where the sample is placed to be measured and the last part is where the meter of radiation ultimately "passes" (not absorbed) through the sample.
