Profesional manufacturer & supplier for test equipment & analytical instruments since 2003.
2008E High low temperature circulators
Compact appearance, small size, very convenient to place in fume hoods, test benches, and under the table;
Front and rear handles make the device very easy to move;
Simultaneously equipped with heating and cooling functions, it can easily achieve precise control of any temperature between -25 ℃ and 200 ℃;
2KW heating power, capable of quickly raising the temperature to the set value;
Multiple safety protections: low liquid level protection, adjustable over temperature protection, can be alerted by both light and sound when an alarm is triggered, meets DIN12876 standard level III, and can use flammable bath solutions;
Equipped with an external temperature sensor, it can control the temperature of external materials;
Maintenance free pressure/suction pump with strong pump power. The pump can simultaneously stir the bath in both horizontal and vertical directions, ensuring good temperature uniformity in the tank;
Large opening design, the container can be directly placed in the tank for reaction, or the test tube rack can be placed in the tank first, and then multiple test tubes can be placed on the test tube rack for sample constant temperature reaction;
The pump pressure and flow rate automatically adapt to external loads, and the international standard M16x1 connecting nut can be configured with different joints to meet the needs of different external circulation pipe diameters;
Parts that come into contact with liquids or vapors are made of high-performance stainless steel and high-performance plastics, which are corrosion-resistant and do not scale;
Fluorine free environmentally friendly refrigerant;
Environmentally friendly refrigerant, non-toxic pollution;
The detachable front ventilation shell makes it easier to clean the condenser and dust screen, extending the interval between repairs and maintenance;
Multiple operation modes to choose from, automatic recovery in case of unexpected power failure;
Optional intelligent control function: Multiple interfaces (RS485, RS232) for remote communication and control of device start and stop;
Optional 0-10V or 4-20mA analog signal input, can be used for external intelligent device control of instrument start and stop;
Optional normally open and normally closed 2 external contacts, which can be connected to external alarms.
An optional set of 12V switch output signals can be used to control external solenoid valves.
