Model 770

770 Carbon Monoxide Monitor by Test Products International

The 770 CO Single Gas Monitor is a state-of- the-art Carbon Monoxide Instrument designed to measure Carbon Monoxide in ambient air and to perform a carbon monoxide build up test . It has a measurement range of 0 to 999 ppm (parts per million) and displays the readings in 1ppm increments.

The unit features a personal audible and visual alarm, which is factory set at 30ppm CO but can be changed in the field to keep current with government legislation.

Other features include: maximum reading hold, elapsed time and manual zero. The audible alarm may be switched on and off as required. Battery changing is made easy by use of a simple slide off battery compartment cover.

The detector uses an advanced electrochemical sensor that measures Carbon Monoxide and should not be used for any other purpose.

When the audible alarm is switched off a small 'double speaker' symbol will be displayed at the bottom left of the LCD. When the alarm setting is exceeded a 'warning' symbol is displayed at the bottom center of the screen and the red warning indicator is illuminated. As the battery level approaches 2 volts a 'BAT' warning symbol is displayed to indicate low battery level. When the battery level gets too low the unit will automatically switch off.
