temperature of combustion of diesel engines generates more nitrogen oxides than gasoline
engines. The TX-6-ND meets the requirements of the Uniform Building Code for enclosed
garages and meets OSHA standards for Nitrogen Dioxide exposure.

Hydrogen Sulfide Detector Controller and Transducer
Provides automatic fan control to help maintain acceptable levels of H2S in refineries, pulp and
paper mills, waste disposal and other commercial facilities - Can be used as a stand-alone
detector and controller and as an analog transducer for use with the DVP-120 and other systems
– ETL Listed

Hydrogen Sulfide or H2S, also called sewer gas, is a colorless gas with a strong odor of rotten eggs.
Note: Sense of smell becomes rapidly fatigued & can NOT be relied upon to warn of the continuous
presence of H
2S. The TX-6-HS is designed to meet the NIOSH and OSHA standards for Hydrogen
Sulfide exposure limits.

TX-6-HS - 12-24VAC or 12-32VDC input and TX-12-HS - 100-240VAC input

• 5A SPDT Fan control relay
• 0.5A N.O. or N.C. Alarm Relay
• Selectable Fan and Alarm Relay Actuation Settings

Ammonia Detector Controller and Transducer
Provides automatic fan control to help maintain acceptable levels of Ammonia in refrigeration,
warehouses, hockey rinks and other commercial facilities - Can be used as a stand-alone
detector and controller and as an analog transducer for use with the DVP-120 and other
systems – ETL Listed

Ammonia or NH3, is a colorless gas with a pungent, suffocating odor. Note: Shipped as a liquefied
compressed gas - easily liquefied under pressure. The TX-6-AM is designed to meet the NIOSH
and OSHA standards for Ammonia exposure limits.

TX-6-AM - 12-24VAC or 12-32VDC input and TX-12-AM - 100-240VAC input

• 5A SPDT Fan control relay
• 0.5A N.O. or N.C. Alarm Relay

• Coverage Area:  900 sq. ft.
• 4-20mA current loop
Provides oxygen detection and automatic ventilation control in wastewater treatment plants,
factories & other commercial applications. The OX-6 is a low level meter capable of detecting
from 0-25% by volume of oxygen. - Can be used as a stand-alone detector and controller and
as an analog transducer for use with the DVP-120 and other systems – ETL Listed

The normal concentration of oxygen in the atmosphere is approximately 20.9% by volume. The
OSHA minimum acceptable breathing air contains 19.5% oxygen. In the absence of adequate
ventilation the level of oxygen can be reduced by breathing, combustion and other processes.

Carbon dioxide (CO2) colorless, odorless gas. Carbon Dioxide is a recognized workplace hazard.
It is significantly heavier than air and many fatalities from asphyxiation have resulted from entry into
pits, tanks, sumps or cellars where CO2 has accumulated and displaced oxygen.
