72L Forced Air Lab Drying Oven/ High Precision Temperature
Controlled Hot Air Drying Oven
Brief Introduction:
This drying oven can provide a stable test space for pre-heating,
drying, changes about physics and chemistry testing.
It controls the temperature through the connection of digital
display instrument and temperature sensor, and adopts the method of
hot air circulating air supply.
The hot air circulation system is divided into horizontal and
vertical type. Air is driven by the blower motor, through the
electric heater, hot air will be sent to the air duct into the
oven, and will use the air intake duct into air circulation
heating, once again, it can effectively improve the temperature
uniformity. If the door is opened during use, the air supply
circulation system can recover the temperature quickly.
Features:
Materials: The shell is welded with high quality steel plate and
the surface is treated by baking varnish. The inner case is made of
mirror stainless steel #304.
The oven adopts PID temperature controller with temperature control
and digital display.It has the timing function, the temperature
recovery is fast, the control temperature is accurate.
The timer can be set in seconds, minutes, 10 minutes, hours and 10
hours, with a maximum time of 9999 hours,overtime will cut off
heating, buzzer tips.
The hot air circulation system is composed of low noise, high
temperature resistant motor and special air duct design, ensuring
the temperature uniformity and small fluctuation.
