For local notification and alarm, the logger’s high contrast LCD shows a variety of temperature and humidity information. At the touch of a button, users can cycle between the current temperature and humidity, along with the maximum and minimum stored values for each.To ensure extended logging sessions, the EL-21CFR-2LCD is supplied with a lithium metal battery, enabling up to 2 years’ operation.
