This series of test
chambers offer a wide range of temperature/humidity
control in accordance with national standard GB/T2423.
1、2、3、4, which regulates the ways to test electrician
or electronic products under four conditions:
A. low temperature; B. high temperature; Ca. invariable
heat/humidity; Db. interchanging heat & humidity.
This test chamber can
satisfy GB10592-89 "Technical conditions
for high & low temperature test chambers",
and GB10586-89 "Technical conditions for
interchanging test chambers".
Adopting the standard of sense organ:
The sense organ is used
to test the temperature & humidity, which
saves the needs of using gauze to maintain it.
It avoids the effect of unqualified water since
no water is needed in the RH testing process.
The independent use of humidifier and purifier
simplifies the structure. |

Performances:
- The product can meet various needs of users due
to extremely large scale in temperature control.
- The unique balanced thermo-control measure can create
ideal temperature conditions. It also has the capability
of heating and humidifying in a stable and balanced
way and can adjust the temperature precisely and steadily.
- The temperature/humidity control system employs
the OYO, U-7651 meters from Japan or the large-sized
IPC1000 touch screen meters from US. Besides, the
temperature/humidity control system is configured
with R232 and 485 communication faucet, which ensures
the long-distance control or centralized control at
users’ convenience. All parameters are displayed in
clear digital forms, and can be configured with temp./humidity
recorder.
- The intellectualized controller in the device can
greatly improve the precision of temperature setting.
- The automatic device has the capability of choosing
operation and refrigeration loop in accordance with
the pre-set temperature. The refrigeration machine
can automatically run in high heat and cool down the
temperature directly. The refrigeration system uses
the imported set of close-circuit compressors in air
swept type.
- The watching widow installed at the gate of the
chamber makes it convenient to inspect the samples
in it.
