PID Lamps

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.

Ease of calibration



10” high resolution HDMI color touch screen


Embedded Pentium Computer with > 1 GByte of RAM; data storage on 1 Gbyte USB memory stick.

Operating system

Windows 10 Operating System

Peak Detection & System Operation

Controlled by our 32 bit PeakWorks software program with more than 20 years of development.


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.


The 312 has 3 ranges with computer controlled autoranging- x1, x 10, x 100.
