11. DUAL PROBE VERSION
11.1. Applications Overview
A dual-probe version of the IEQ Chek
is available for applications that require
remote monitoring of gas, temperature, and relative humidity. This version offers two
unique probes:
•
High humidity gas sample probe (P/N: 1509-0021)
•
Temperature/RH probe (P/N: 1509-0024).
NOTE:
The calibration/sample adapter (P/N: 1509-0022) is common to
all
pumped
IEQ Chek
versions and is included with the dual-probe version.

Probes
Applications that are well-suited for the dual-probe version have the following
similarities, though they are not exclusive prerequisites of using the dual-probe
version:
•
High humidity environments
•
Measurement of carbon dioxide gas levels
•
Impractical or impossible to physically relocate the standard “single probe”
instrument (and its built-in temperature and humidity sensor) into the
environment being measured.
The IEQ Chek
dual-probe version can be used in high-humidity applications that
require CO
2
monitoring, such as research incubators and horticulture applications
(e.g., greenhouses, mushroom farms, etc.).
For example, the IEQ Chek
can be used to monitor key environmental levels within
lab incubators commonly used in medical and research facilities. Lab incubators
need to provide constant temperature, humidity, and carbon dioxide (CO
2
) levels to
control the correct atmosphere for cell or tissue cultures, embryos for IVF, and stem
cell research applications. The incubator units typically have a built-in monitoring
system for CO
2
while more sophisticated units have additional monitoring for oxygen
(O
2
) levels. Because it is critical that these levels are kept constant, the incubators
require a way to verify that the levels shown by the internal monitoring system are
correct. Bacharach’s IEQ Chek
provides this verification.
The IEQ Chek™ accurately and reliably monitors key environmental levels within
incubator chambers. It uses a remote sample probe to quickly confirm the CO
2
(and
O
2
if installed) through the CO
2
sample port built into the incubator. With built-in
