FAQs

FAQs

Q.Are the data loggers robust and unobtrusive?
A.Data logger units may be provided with ruggedised housings to improve durability and reduce the risk of environmental or deliberate damage. For urban environments loggers may be supplied with enclosures designed to resemble street furniture such as bollards.
Q.Are the data loggers ATEX certified?
A.Hydro-Logic® data loggers are available with ATEX certfication for use in explosive atmospheres. Please contact us to discuss your exact requirements.
Q.Is the unit waterproof?
A.Most Hydro-Logic® data loggers are waterproof to IP68 standard. Depending on application, some models are waterproof to IP65 standard.
Q.Is data transmitted automatically?
A.All Hydro-Logic® data loggers can be configured to operate autonomously and remotely, transmitting data automatically. Data may also be collected manually if preferred.
Q.Which sensor do I need for my data logger?
A.The right sensor type will depend on the conditions at the site in question and on your specific data gathering requirements. One size does not fit all, and selecting an inappropriate sensor could result in meaningless data—or no data at all. We have decades of experience in hydrometric data logging, and our experts will advise you on which sensor(s) will meet your needs.
