Features

PID Lamps FID FPD Ease of calibration
Our 9.5 and 10.6 eV lamps remain the best in the business since we developed them over 30 years ago. Our very sensitive FID has flame out sensor that will shut off the hydrogen if the flame goes out. Our very sensitive FPD has flame out sensor that will shut off the hydrogen if the flame goes out. Manual.
Display PC Operating system Peak Detection & System Operation
NA - Requires external PC (not included). Requires Pentium Computer (not provided) with > 1 GByte of RAM and hard drive > 40 Gbyte. Windows XP® (not provided). Controlled by our 32 bit PeakWorks software program with more than 20 years of development.
ADC Autoranging Autozero Programmable Voltage/current output
Our 16 bit ADCs provide a resolution of 1 part in 64,000 and our signal algorithm minimizes noise by signal averaging in the msec range; the ADC can acquire positive or negative signals- Uses USB connection to external PC. The 322 has 3 ranges with computer controlled autoranging- x1, x 10, x 100. Beginning of each run. 0-1VDC.
