constant low temperature bath
 
 
 
Water Bath Series

 specifications


   

 

¡¤introduction

the constant low temperature bath is comprised of a refrigeration compressor system and a high precision thermostat which combines the microprocessor and the pid control techniques. the constant low temperature bath is widely used in industries such as petroleum, chemical, medicine, biochemistry, metrology and other light industries and scientific research etc.

¡¤features

control panel
digital display, easy setting and operation, adjustable temperature, alarm signal display
advanced thermostatic controller
high temperature control accuracy of ¡À0.02¡æ
wide temperature control range; temperature can be controlled and set at will in the range of -10¡æ.-95¡æ.
environmentally friendly compressor refrigeration system.
the compressor contains no cfc`s of hcfc`s; continuous operation in the range of ¨C10¡æ-45¡æ, high cooling rate, high cooling power at low temperature, automatic switching on or off of the compressor.
circulation system
the bath is fitted with a powerful jet-pump for agitating and has joints connected with the external circulation system.
safety features
low liquid level protection

if the water level is too low the heating pipe will shut off and the alarm light will illuminate.

temperature out of control

if the temperature exceeds the preset level by 2¡æ during the thermostatic process the heating pipe will shut off and the alarm light will illuminate.

protection of compressor

(in the case of high working temperatures) if the temperature inside the bath exceeds 45¡æ the alarm light will illuminate and the compressor will be disabled to protect the refrigeration system, thus more reliable operation is assured.

over current protection

if the electrical current is exceeded during the course of operation the internal fuse will blow thereby protecting the apparatus and the operator.

external sensor
  external circulator
¡¤equipped with an outside connector by which the external circulation can be controlled.
¡¤with free control options of the internal and external circulation the device can meet customers demands.
