Environmental Sensors

Environmental sensors are utilized in a wide range of indoor and outdoor air quality monitoring applications. They come in different shapes and sizes, with different communications options, with or without a display, wall or duct mounted and with varying specifications, features and performance.

Alpha Scientific is very selective in relation to types and brands of sensors we source and offer to our customers. We have decades of experience in supplying environmental sensors in cleanrooms and controlled environments, buildings for indoor air quality monitoring and for many outdoor air quality monitoring applications.

Cleanrooms & Controlled Environments

Environmental sensors used in cleanrooms and controlled environments are quite different to those that are commonly used in HVAC systems, BMS systems, buildings, offices, homes and other environments. Their measurement range, accuracy, suitability for cleanroom environments and other factors all come into play including their ability to be calibrated and re-calibrated in accordance with GMP and industry requirements.

Temperature, humidity, differential pressure, particle counters, gas and other sensors are all commonly used in cleanrooms and controlled environments and selecting the right sensors can make a world of difference in accuracy and reliability.

Indoor Air Quality Monitoring

Environmental sensors used for indoor air quality monitoring generally dont require the same level of accuracy & traceability when compared to cleanroom style sensors. That said, Alpha Scientific is still very selective in those sensors we use for indoor air quality monitoring applications. Sensors suitable for indoor air quality monitoring are commonly used in HVAC systems, BMS systems, buildings, offices, homes and similiar environments. Some are standalone devices, others may be connected to monitoring systems. Initial calibration and annual re-calibration is still advisable to maintain measurement accuracy.

Outdoor Air Quality Monitoring

Environmental sensors used for outdoor monitoring are considerably different to those used in cleanrooms and indoor air quality monitoring applications. They need to be adequately protected against the outdoor elements (rain, wind, birds etc) and often their temperature range needs to be wider to cater for outdoor temperature variations. They still need to be accurate, stable and reliable and have similiar communications options in order to be able to connect to outdoor telemetery systems, data loggers and other data collection devices. Most quality sensors come calibrated and re-calibration may be undertaken annually or as customers require.
