Compact design for personal use
Ready to network with your computer.

Introducing a new lineup of our Bench-top Type Temperature (& Humidity) Chamber Series.

Our latest models achieve superb performance in a compact size,

and attains temperatures as low as −20℃/−40℃/−60℃, with capacity of 20L or 60L.

They provide high performance and quality features with new capabilities for integration

with our information network system,〈E-PILOT 21〉.

It is useful for centralized control and data processing, as well as operating chamber control

and specimen measurement at the same time. All brought to you by ESPEC.

Viewing window and stand are optional

The new model SH-661 achieves −60
to ＋150℃/ 30 to 95%rh in a compact
design, and shows outstanding perfor­mance than any other previous bench­top models.

Select your optimum
chamber from a full variation

The series provide six variations in
temperature (& humidity) range of

−20℃/−40℃/−60℃

to ＋150

℃

(and 30 to 95%rh), and two capacities of
20L or 60L, with a total of 10 models
altogether. A wide temperature (&
humidity) range is offered in a bench­top model, enabling you to choose the

User-friendly

Newly developed refrigeration
system that saves energy
consumption up to 55%

Our exclusive refrigerator capacity
variable control system saves up to 55%
energy consumption compared to our
previous model.

Optional stand for
space-saving layout

For use in limited space, we provide an
exclusive stand with casters for stacking
up to three chambers.

*Be sure to secure the stand onto the floor with earthquake

resistant fittings for your safety when using stand.

Recycling

Molded resin and metal parts which can
be recycled are clearly marked to make
recyclable materials easier to identify
during disassembly.

Ozone layer protection

The HFC refrigerant used is completely
safe for the ozone layer.

Paperless Recording (optional)

The paperless recorder makes it easy
record the temperatures of different
components, such as the chamber
temperature, on a memory card (Compact
Flash).

Cable port flug (Material marked)

Paperless recorder Portable type (optional)

Water supply tank

Right-opening door Viewing window: 20L model

Cable ports for running in
wires

Each one 25mm diameter cable port is
standard equipped on both sides of the
chamber for wiring to the specimen. We
also provide 50mm, 100mm diameter
port and flat type cable port.

Cartridge tank for easy
water supply

Once water is supplied into the tank,
continuous operation is maintained for
three days. Maintenance can be done
easily from the front side. Additional
water tank connection is available for
further extended operation. (SH model)

Right-opening door (optional)

You may want to change the direction of
opening the door to fit the installation
space.

Viewing window for
observation (optional)

A large window provides a clear view of
your specimen during testing.
(215W×215Hmm for 20L model,
215W×315Hmm for 60L model)

*The basic specification of the chamber will be modified.

Flexible Computer Interface

Communication port RS-485 is
equipped as standard. You can select
RS-232C, GP-IB, and E-BUS communi­cation port as option.

humidity limit alarm setting can be done
with simple key operation.

Programming operation of
up to 9 steps

In addition to constant setting,
programming instrumentation is
equipped to allow programmable
operation to a maximum of 9 steps per
pattern and the rise and fall gradient of
temperature (& humidity) to be set to
meet the application requirements for
temperature characteristic testing and
temperature (& humidity) cycle testing.
Maximum 99-time repeat function and
operational setting function after
program execution are just two of the
various functions offered.

E−PILOT《ERC-200M

》

E−PILOT《ERC-300M

》

Set up an Intranet Web-PILOT site to allow monitoring of up
to 16 chambers through one PC (possible with E-BUS
communications system). Monitor the settings and operation
of your chambers from any PC on the Intranet. Web-based
method allows display of chamber information across many
computer platform types.

Control, monitoring, programming, and datalogging for up to
16 ESPEC chambers can be performed through a single PC.
RS-485 from ESPEC chambers connect via a serial bus
converter to RS-232C on the PC.

●

Remote operation

Have full control of test chambers while sitting in your office.

●

Potential savings

Because the ERC-200M allows program operations to be run
directly from the PC, test chambers with less-expensive
single-setting controllers can be used.

●

E-BUS version available

For existing units with E-BUS system, ERC-100M is
available.

E−PILOT《ERC-100S

》

E−PILOT《LabVIEW

》

Provides an interlocking system of testing and measuring
devices that allows customers currently using LabVIEW to
link to ESPEC chambers, opening new horizons for
environmental testing. Optional E-BUS or GP-IB (IEEE-488)
communications interface is required.

●

Driver software to connect test chambers are provided
for free

Lab VIEW drivers are available to give the basic building
blocks for addressing ESPEC equipment. Drivers required for
connecting ESPEC products to a personal computer is
provided for free. For further information, please contact your
nearby ESPEC sales office.

The high-level of functions offered by ERC-200M is included
in a non-networked package, meant for a single chamber to
be interfaced with your personal computer. The RS-232C
communications port option is required, but the software is
free.

●

For one-to-one users

If you are not ready to establish a network of test chambers,
this software would be an ideal trial of the capabilities of our
ERC-200M package.

●

Freeware

ERC-100S can be downloaded from our website for free at

www.espec.co.jp/english.

CMS−J30

This is a fully customizable system that provides centralized
control, centralized monitoring, remote operation and
specimen data management of ESPEC products (up to 32
units of which 16 are dedicated to centralized monitoring) by
the use of a PC. (E-BUS compatible)

* Please contact us for further information.

* The series of application softwares and network systems are provided on a

separate basis from the chamber.

Communication Network of
Environmental Test Chambers

Bench-top type temperature & humidity
chamber incorporates the communi­cation port RS-485 as standard to cope
with the［E-PILOT 21］, which is a
newly developed centralized control
system.［E-PILOT 21］not only serves
as a system for centralized control of
environmental chambers, but also
establishes an open network including
specimen measurement function and
remote chamber main-tenance function.
