Casella offers a diverse range of highlysophisticated sensors to monitor a variety ofenvironmental parameters from wind andtemperature to radiation and cloud base. Other environmental parameters such as water characteristics and gas detectors may also be fitted. Many of these sensors have been designed and manufactured in-house based upon many years of experience in the transducer market.

Sensors can be supplied as part of an environmental monitoring system, such as the Automatic Weather Station or Mobile Ambient Air Monitoring Laboratory (see ‘Ambient Air Monitoring’ in this section), or separately, as part of a customer’s monitoring project. All transducers are supplied with individual calibration details and with a limited amount of interconnecting cable. Longer cable lengths are available on request.

Due to the large number of sensors available, only a small selection of those most commonly used are shown here.
