Chemistry Instruments

Atomic Absorption

Atomic Absorption equipped with graphite furnace for the determination of metals. (AVANTA P, GBC).


A mass spectrometer with inductively coupled plasma is used for the determination of trace elements, isotopes and rare earth elements (ELAN 6100, PERKIN ELMER).


The method of molecular absorption spectrometry is used for the determination of ions such as NO3-, NO2-, PO43-, etc. (DR2000, DR4000, HACH).

Radon meter

Determination of Radon levels that are dissolved in groundwater (220Rn/222Rn). (RTM 2000, SARAD).


A mass spectrometer used for the determination of 18O and 2H is also available. (DELTA PLUS, FINNIGAN).

Portable devices

A large number of portable devices for the determination of physicochemical parameters in groundwater such as portable pH-meter, conductivity, instruments for measuring temperature, dissolved oxygen, redox potential and other parameters such as ammonia, nitrates, etc are also available. Apart from these devices many other such as computers, Differential GPS, barometers, etc. are also available.

Devices for permanent establishment

Automated Water level meters

Used for continuous record of water level. Besides the mechanical ones, the Laboratory of Hydrogeology owns the latest type of electronic instruments with adjustable time step and very high data capacity. (Thalimedes, Orpheus mini, OTT).

Data loggers for hydrochemical parameters

They have the option to record and transmit the recorded data. They are supplied with sensors for the determination of water level, pH, redox potential, dissolved oxygen, temperature and conductivity in wells. (KILL, SEBA).

Automated weather stations

The Laboratory of Hydrogeology has two automated weather stations for recording of rainfall, air and ground temperature wind speed and direction, air humidity and sunshine. (Maws, VAISALA).

Portable equipment

Current meters

Different types of mechanical current meters for small and large sections. (C2, C31, SEBA) A device for measuring water velocities ranging between 0.025 and 10 m /sec whose function is based on electromagnetism is also available. (EMS, DELFT).

Portable water level meters

They are used to measure water level in wells up to 300 meters depth. The Laboratory of Hydrogeology owns various types of water level meters; some of them have the ability to record and transmit real-time data of water level but also water temperature, conductivity, redox potential and pH. (KLLQ, SEBA).

Apart from the devices mentioned above, that compose the basic equipment, other devices as Computers, special GIS software, underground water flow simulation, hydrochemistry, auxiliary devices as GPS, barometers and more are part of the Hydrogeology Laboratory's equipment.
