The CL11 is a precise, portable instrument that can measure and save relative humidity, temperature and CO2 content and the temperature of the external probe.
Programming
Most settings, such as clearing the memory, CO2 alarm, alarm tone ON/OFF, CO2 display, units (°C/°F), sampling rate, pressure equalization and real time clock can be changed with the function keys.
Power Supply
The CL11 is charged with a 5 VDC AC adapter (AC1214).
Connecting to PC or Laptop
Connect the CL11 to a PC or laptop using a mini USB cable. The stored data can then be downloaded easily with the HygroSoft software. The software can be downloaded free of charge from www.processsensing.com or www.rotronic.com.
