Overview

The oil bath circulator is made of stainless steel plate and mechanical processing technology, and has the characteristics of high temperature resistance and corrosion resistance. The temperature control performance is stable, the heat balance time is short, the temperature fluctuation is small, the uniformity is good, and the LED display is intuitive. It is widely used in laboratories of universities, colleges and universities, environmental protection, scientific research, sanitation and epidemic prevention, petroleum, metallurgy, chemical industry, medical treatment and other units.

Oil Bath Circulator

The oil bath circulator is a constant temperature device with liquid as the medium commonly used in experimental work. According to the temperature control range, the following liquid media can be used: ethanol or ethanol aqueous solution for -60°C to 30°C; water for 0°C to 90°C; water for 80°C Glycerin or glycerin aqueous solution is used for ~160 degrees; liquid paraffin, cylinder lubricating oil and silicone oil are used for 70 degrees to 300 degrees.

Composition of oil bath circulator:

The oil bath circulator is generally composed of a bath, a heater, a stirrer, a thermometer, a temperature sensing element, a thermostat controller and other parts.

1. Transparent tank, oil bath circulator for Ubbelohde viscosity test

A glass tank is usually used to facilitate observation, and its capacity and shape depend on the needs. Physical and chemical experiments generally use a 20L round glass tank. The liquid in the bath tank is generally distilled water. When the constant temperature exceeds 100°C, liquid paraffin or glycerin can be used.

2. Heater:

The electric heater is commonly used. The power of the electric heater is selected according to the capacity of the oil bath circulator, the constant temperature and the temperature difference with the environment. For example, a large oil bath circulator with a capacity of 20L and a constant temperature of 25°C generally requires a heater with a power of 1700W. Improve the efficiency and accuracy of constant temperature,

3. Stirrer: Generally, a 2300r/min motor is used

4. Thermometer: pt100 is commonly used as a sensor

5. Temperature sensing element: it is the sensory center of the oil bath circulator and the key to improving the accuracy of the oil bath circulator. There are many types of temperature sensing elements, such as contact thermometers. Thermistor temperature sensing element, etc.

Benefit

Features of oil bath circulator:

1. Unique large-screen backlit LCD display, clear and clear information such as set temperature, actual temperature, heating power, and working status

2. High-performance single-chip microcomputer control, self-tuning PID adjustment, imported platinum resistance temperature measurement, high temperature control accuracy and small fluctuation

3. High-performance stirring motor, low noise, low heat generation, fully enclosed, long life

4. Stainless steel platen and liner can effectively avoid corrosion, rust and other phenomena

5. It has the functions of burnout protection and over-temperature alarm, and provides multiple security measures

6. The instrument works stably and reliably, and is convenient and safe to operate

Factors affecting the sensitivity of oil bath circulator:

1. The constant temperature medium has good fluidity, good heat transfer performance, and high temperature control sensitivity;

2. The power of the heater should be appropriate, and the temperature control sensitivity should be high;

3. The relay electromagnetically attracts the electric key, the shorter the mechanical action time of the latter, the smaller the remanence of the iron core in the coil when the power is off, and the higher the temperature control sensitivity;

4. Electric contact thermometers have small heat capacity and are sensitive to temperature changes, so they have high sensitivity;

5. The smaller the difference between the ambient temperature and the set temperature, the better the temperature control effect.
