ELECTRICAL TESTING

• Protective electrical insulating equipment and tools (gloves, shoes, boots, helmets, pliers, stools, poles, voltage indicators, plates, partitions, mats)
• High-voltage testing of transformer oils (dielectric strength)
• Electrical installations
• Electrical installations in Ex (explosion-proof) design
• Lightning protection installations
• Lightning protection installations in Ex (explosion-proof) design
• Power plants (grounding resistance, system impedance, galvanic connection, touch and step voltage, winding insulation resistance, busbars, and insulators)

NON-IONIZING RADIATION

• Measurement of exposure levels to non-ionizing radiation – low frequencies
• Measurement of exposure levels to non-ionizing radiation – high frequencies
• Measurement of contact current

PHYSICAL TESTING

• Physical testing (noise in the work and living environment, human vibrations, illuminance, dust)

INSPECTIONS AND TESTING

• Measurement of mechanical vibrations on machines and plants

MICROCLIMATE AND HARMFUL RADIATION

• Temperature, relative humidity, and air velocity
• Harmful radiation – UV and IR

PHYSICO-CHEMICAL TESTING

• Air – ambient air quality (PM2.5 and PM10 particles, heavy metals Pb, As, Cd, and Ni in PM10 particles, gases CO, SO2, NO, NOx, O3, benzene, benzo(a)pyrene)

• Soil – physico-chemical testing (pH, heavy metals, organotin compounds, PAHs, PCBs)*
• Water – physico-chemical testing (temperature, pH, electrical conductivity, ammonia, phenols, fluorides, phosphates, heavy metals, organotin compounds, PAHs, PCBs)*
• Transformer oil – determination of PCB concentration

MECHANICAL TESTING
