For environmental noise monitoring when short measurements are required using a hand held Sound Level Meter, for boundary monitoring of industrial sites or noise surveys for planning purposes. Measurement of vibration on structures where piling, rock breaking, blasting are taking place or rail and road traffic monitoring.



With intuitive 2 key operation, the CEL-240 is an easy to use instrument designed to undertake noise measurements for a variety of applications. The primary role of the CEL-450 model is an occupational hygiene instrument.The main role of the CEL-490 is as an environmental instrument. Whether simple or in-depth measurements are required, an appropriate meter from the CEL-450/ 490 range can be selected for the application.



For monitoring settlement or heave under structures and observation of ground movement caused by construction excavation or fill placement. Cutting edge MEMS technology for the measurement of lateral displacement of soil.



Used to measure tilt in either one or two axial planes perpendicular to the surface of the base plate. Provides precision real-time remote monitoring of tilt of submerged structures. For the measurement of differential movements in structures.
