Product Notes
For many applications that require the monitoring of both ambient temperature and
humidity, the RHTemp101A is the ideal solution. Used for warehouse and museum
monitoring as well as HVAC studies, the RHTemp101A can measure ambient temperature
from -40 °C to 80 °C and humidity from 0 %RH to 95 %RH.
LEDs
- Green LED blinks: 10 seconds to indicate logging and 15 seconds to indicate delay start
mode
- Red LED blinks: 10 seconds to indicate low battery and/or memory and 1 second to
indicate an alarm condition
Password Protection
An optional password may be programmed into the device to restrict access to
configuration options. Data may be read out without the password.
