electric heatingconstant temperature water bath
Usage Overview
Single row single hole electric constant temperature water bathIt is an auxiliary constant temperature experimental instrument, consisting of a shell, an inner tank, and a temperature control device. It is mainly suitable for evaporation and constant temperature heating in various laboratories. It is widely used for distillation, drying, concentration, and temperature preservation of chemical drugs or biological products. It is an ideal tool for laboratory technicians in major universities, environmental protection, scientific research, health, epidemic prevention, petroleum, metallurgy, chemical, medical and other units.
Product Features
Single row single hole electric constant temperature water bath
vMicrocomputer PID temperature controller, large screen LCD instrument display, with timing function, easy operation, precise temperature control;
vThe temperature control system uses high-precision sensors and tightly integrated components, with strong thermal sensitivity, high sensitivity, and precise and reliable instrument temperature control;
vMulti functional PID control unit, microcomputer processing chip backlight display clear reading, dual digital display function, can display real-time temperature and set temperature;
vThe box adopts multi-layer waterproof insulation, which ensures no leakage of water. A drain valve is added at the bottom for easy water change, with one key switch and simple operation;
vThe surface adopts electrostatic spraying technology, and the upper cover of the inner liner is made of stainless steel plate, which is corrosion-resistant, effectively prevents rust, and is beautiful and durable;
vThe interior of the water bath pot is a mesh shaped stainless steel shelf, and the stainless steel cover is equipped with combination rings of different diameters, which can adapt to flasks of different diameters;
vEquipped with parameter memory and call recovery functions to protect against data loss caused by power outages or crashes;
vAlarm temperature points can be set according to experimental needs. If the temperature is too high or exceeds the set temperature, an automatic alarm will be triggered to ensure the safety and reliability of the experiment;
vBuilt in water level sensor, when the sink is powered on, the anti dry burning function will be in a monitoring and protection state. If there is a shortage of water, the heating will automatically stop and an alarm will be triggered (F series).
vIt has two functions: heating and magnetic stirring, and adopts stepless speed regulation or instrument set speed,LED digital display;
vThe magnetic stirrer is made of refined polytetrafluoroethylene and magnetic steel, with high temperature resistance, wear resistance, chemical corrosion resistance, and strong magnetic properties;
vMulti link can simultaneously heat and stir multiple samplesImmersion ring heating, fast heating rate, uniform temperature, precise temperature control; The JOH collector mixer has a large force distance, corrosion resistance, low heat loss, and high temperature, and can heat and stir oil substances.
v30 segment programmable intelligent program controller, temperature can be programmed, and different temperature time combinations can be set arbitrarily (optional accessories);
vThe automatic water supply function requires an external water source. When the water level in the water tank reaches the set level, the equipment can automatically replenish water after connecting to the water source (optional accessories).
