New! 780 Low Level Carbon Monoxide Monitor. The 780 is easy to use and features a two key operation.

The TPI 780 is a low CO monitor of use in work and living spaces. It can be set on a flat surface or mounted to a wall using the included hardware.

The 780 displays the real time CO concentration, peak CO concentration in a 24 hour period, and COHb%. It has visual and audible alarms.
Unlike standard CO monitors that don’t alert to low level carbon monoxide the 780 will display the level of CO from 0ppm and above and audibly and visually alert at 10ppm.
Standard CO monitors designed to UL2034 don’t alert until 70ppm is detected for up to 4 hours.

The 780 has an easy to read display with annunciators for low battery, real time ppm display, peak CO display, and COHb%.

Whether you are wall mounting the 780 or using it on a flat surface there are some items to consider regarding the location of the 780.

If wall mounting the 780 it is best to install it at head
If you are using a single 780 in a house it is best to locate the unit in the bedroom or within approximately 10 to 20 feet of the Monitoring for CO while asleep is very important.
If you are using a single device and if you have an infant, young children, elderly person, or a person with lung or heart related health issues living in your household it would be best to locate the 780 near the area where they sleep because they are at much higher risk to low level carbon
If using a single 780 in an office environment locating it in a central area is best. Mounting it near a thermostat is also an option if the thermostat is in a central
Using more than one 780 is a great way to ensure your entire living or work space is being

Do Not locate the 780 where it may be obstructed from sampling air like behind curtains.

Do Not locate the 780 near heat vents, chimneys, flues, or combustion appliances like stoves, furnaces, or fireplaces.

Do Not locate the 780 outside or anywhere temperatures could drop below 32°F (0°C) or above 104°F (40°C).

Do Not locate the 780 where it may come in contact with liquids or moisture of any kind.

If you are mounting the TPI 780 to a wall please follow the steps below:

Remove the battery cover on the back of the instrument by sliding the cover down and then lifting it off from the
Using the battery cover as a template, mark where the holes are located for the screws to mount the 780 to the wall. (Alternately the hook and loop tape fasteners can be used to mount the 780 to the wall or other flat surface)
Drill holes for the plastic screw anchors. Insert the anchors into the wall and insert the screws into the anchors. (If using the hook and loop fastener tape, remove the backing from one piece and attach it to the 780 then remove the backing from the other piece and attach it to the wall or flat surface)
Tighten the screws into the anchors leaving enough room between the screw head and the wall to slide the battery cover on the screw
