NOTE: To guarantee specified accuracy, the StowAway TidbiT loggers should not be used in wet condensing environments (> 90% RH) and water temperatures higher than +30°C (+86°F) for more than 8 weeks cumulatively. Prolonged exposure will lead to measurement drift and eventual failure. Use the HOBO Water Temp Pro v2 for applications in wet environments over 30 °C (86 °F). For depths greater than 300m, use the HOBO Stainless Temp Data Logger.
