Heath Consultants Detecto-Pak 4 (DP) - Manual (Page 6)

FUNCTION
The Heath Detecto-Pak 4 Flame Ionization Hydrocarbon Detector
is designed to detect and measure the presence of hydrocarbons
(calibrated for methane). The instrument has five sensitivity ranges:
10, 50, 100, 1,000 (1K), and 10,000 (10K) ppm (1% gas).
This instruction manual describes the operation of the instrument and
provides limited maintenance information. Heath firmly believes the
Detecto-Pak 4, when properly maintained, will provide reliability and
ease of operation for many years.
