basic information
This circular chart paper type temperature, humidity, and dew point recorder records temperature changes with a red pen and humidity changes with a blue pen on a circular chart paper with a diameter of approximately 15 cm. It is powered by a 12V DC supply obtained from a power adapter (either 110V AC 50/60Hz or 220/240V AC). If a 12V DC supply is available, it can also be used with storage batteries, including those for automobiles and ships. In the event of an unexpected power outage, it can operate for up to approximately 48 hours on backup power (8 AA alkaline batteries). By using this circular chart paper type temperature, humidity, and dew point recorder, you can simultaneously monitor temperature and humidity changes. The rotation speed of the chart paper can be selected from 12 hours, 24 hours, 7 days, or 31 days. The measurable range is from -30°C to 50°C (-20°F to 120°F) for temperature and 10% to 90% RH for humidity. Dew point temperature is also calculated. It features a large, easy-to-read LCD display and an alarm function that alerts you to temperature deviations with sound. ■ Usage Examples Cold storage facilities, greenhouses, vinyl houses, livestock breeding facilities, food and ingredient processing facilities, laboratories.
