Description
Model PT104 "Quad
Alert" is a rugged microprocessor based portable
monitor designed for environment where toxic and combustible
gas hazards may exist. The unit is designed to be a
dependable means of protecting orkers in confined spaces.
The unit features a built in sample-draw pump for continuous
sampling and pre-entry testing of confined spaces. A
dust and hydrophobic filter prevents moisture and contaminants
from being drawn into the sampling system.
PT104 can be used to up to four
gases. The standard unit comes with four sensors, combustible,
oxygen deficiency and 2 toxic. The unit features two
alarm levels with audible and visual indication and
has fail safe features such as low battery and low flow.
The unit continuously monitors and displays the concentration
on the LCD display. Peak readings are recorded and can
be displayed upon demand by simply pressing the switch
provided on the front panel. Optional data logging is
available
