1 System Description
The Honeywell EC-P2 is a portable, battery operated instrument for the measurement
of gas concentrations in ambient air.
The Honeywell EC-P2 can be converted from one target gas to another by simply
plugging in a different SMART-CELL for the desired target gas (takes about 30
seconds). This allows one instrument to detect a number of different gases. All
calibration and alarm setpoint data is stored on the individual SMART-CELL so
reconfiguration is not necessary when changing target gases. Extra SMART-CELLs
should be kept on the optional sensor keeper when not in use to keep them “warmed
up” and ready for immediate use.
The Honeywell EC-P2 utilizes two different batteries to insure that you’ll never be
without power when you need it. The primary power source is a “D” size alkaline
battery housed in the handle. It will run the unit approximately 75 hours. When
this battery is removed or dead, the unit will switch to its standby power source,
an internal rechargeable NiCad battery, which will run the unit approximately six
hours. When not in use, the unit should be plugged into the charger to keep this
standby battery charged. If desired, the unit can be run continuously when plugged
into the charger.
The Honeywell EC-P2 also has advanced capabilities such as data logging to an
Excel spreadsheet, 0 to 1.0 Volt DC analog output capability, and a sampling mode
for taking a single reading in a controlled, repeatable manner.
