curves, etc.
Product features:
1. The inner and outer boxes are connected with reliable grounding.
2. The inner box of the equipment is made of stainless steel, which
is not easy to produce metal collision spark.
3.The observation window adopts explosion-proof vacuum glass to
prevent the glass from breaking and injuring the operator.
4.Overtemperature protection device:The equipment is equipped with
an independent overtemperature protector, namely a secondary
temperature protection instrument, to prevent the risk of
overtemperature in the working room.
5.Heating system:Explosion-proof heater is used.
Control system
With a wide temperature and humidity control range to meet the
needs of users.
The unique balance temperature adjustment and humidity adjustment
method can be used to adjust the ideal temperature and humidity
environment. With stable, balanced heating and humidifying
capabilities, high-precision, high-stability temperature and
humidity control is possible.
Temperature and humidity control adopts touch intelligent
programmable temperature regulator
(PID+SSR/SCR forward and reverse bidirectional synchronous output),
including computer advanced slope control logic, with R'S-232C and
485 communication interface device, which is convenient for users
long distance control And centralized control. Computer connection
control, editing, recording and two sets of dynamic contacts (TIMER
SINGAL RELAY), and can be equipped with temperature recorder.
All components of heating, cooling, humidifying and dehumidifying
are completely controlled by microcomputer. The system is
completely independent. It is equipped with intelligent controller,
which greatly improves the setting precision.
Program correction, clearing, scheduled start, power failure
memory, etc.
Automatic selection of the refrigeration circuit: The automatic
control device has the function of automatically selecting the
running refrigeration circuit with the set value of the
temperature, and start the refrigerator to cool down under the high
temperature state. The refrigeration adopts the air-cooled
compressor group and adopts the fully enclosed compressor
The door is equipped with a light observation window for easy
observation of the test condition of the test sample.
Touch screen smart programmable temperature regulator
Microcomputer large LCD (320*240 dots) Chinese and English display
control system, LCD touch panel, backlight 17 adjustable, curve
display set value display value, curve and display a variety of
alarms, Display faults through the screen, eliminate misoperations,
multiple sets of PID control function, and in a form of data
displayed on the screen
Temperature and humidity electric heating circulation system
Heating system: fin heat pipe type stainless steel electric heater;
Circulatory system: special moisture-proof and heat-dissipating design, stainless
steel extended shaft circulating motor, with high-temperature,
low-temperature aluminum alloy multi-blade fan blades;
Air deflector design: can be adjusted up, down, left and right to ensure uniform
distribution of temperature and humidity;
Control method: Balanced temperature control system (BTHC), the SSR is controlled
by P.I.D., so that the heating and humidifying amount of the system
is equal to the amount of humid heat loss, so it can be used stably
for a long time.
