This temperature/humidity recorder is fully compatible with T&D™s popular 500 series of wireless data loggers and collectors and records over a wider range, measuring temperature from -25°C to +70°C (-13°F to +158°F) as well as relative humidity levels from 0-99% RH. Temperature recordings are made at a high 0.3°C accuracy, and humidity readings at a 2.5% RH accuracy. Users can also calibrate using an internal adjustment function, making logging even easier. As with all of the RTR-500 product line, these new solutions enable automatic error-free data downloads for convenient data collection and retrieval.
The Data Loggers in the RTR-500 Series only function as Remote Units. They require one of the following: Base Unit or Hand Held with which to carry out wireless communication.
