GENERAL DESCRIPTION

The Cal 2000 is a battery-powered, portable electrochemical
gas generator designed to calibrate toxic gas sensors. Fast
warm-up time allows the instrument to be turned off between
remotely located sensors saving battery life and avoiding gen-
eration of unwanted gas. A built-in mass flow sensor provides
accurate flow control and the ability to measure externally pro-
vided sample draw flow rates. The Cal 2000 uses the follow-
ing components to produce the calibration gas/air mixture:
Internal Micro Pump
A small, rotary vane, micro air pump draws in ambient air to
blend with the generated gas. The pump may be disabled for
use in calibrating sample draw instruments.
Electrochemical Generating Cell
The electrochemical generating cell contains an electrolyte
solution and either inert or consumable electrodes, depend-
ing upon the gas being generated. A precise concentration of
gas is produced when a known amount of current and a known
amount of air is supplied continuously to the cell. Each cell
has a built-in memory chip that tells the Cal 2000 instrument
what type and range of gas can be generated and how much
cell life is remaining. The electronics board mounted to the
cell should never be removed from the cell. Removal of this
board will void warranty and destroy the cell. Due to the de-
sign characterization of the cell, the unit must be oriented flat
(on the units feet) for correct concentration output.
