Sensors Ease of calibration Datalogging Display
Two IR sensors and two electrochemical sensors. The two point calibration for each sensor uses a zero gas and a span gas. The time to calibrate is about 30 seconds. The Cal button is located on the main menu for ease of use. Manual or automatic datalogging (7,000 points) is available. The 108P has a built in real time clock. Viewer software (Windows 98-XP compatible) comes with the 108P. Our 2 line by 16 character display can be backlit. The upper display provides the concentration and the bottom display provides the sensor, units, alarm and logging mode.
Backlit LCD Display ADC Programmable Voltage output Optional sampling system available
Allows for easy visibility. Our 16 bit ADC provides a resolution of 1 part in 64,000 and our signal algorithm minimizes noise by signal averaging in the msec range. 0-1VDC. View our PDF for more information.
