Haozhuang brand constant temperature oscillator is divided into two categories according to the driving mechanism
It is well known that thermostatic shakers can be used for scientific research in plants, organisms, microorganisms, genetics, viruses, medicine, environmental protection, food, petroleum, chemical industry, etc., for precision cultivation of various organisms in educational departments, research in genetic engineering, heating of petrochemicals, etc.
Instructions for use â‘ Turn on the power, and the self-test will end in about one minute. If "000" is displayed, the sensor is open or the input signal exceeds the measurement range.
â‘¡Press the SET key to set the temperature, press the SET key until the lower row of the code tube flashes, indicating that the meter enters the temperature setting state, press the â–³ key to increase the set value, press the â–½ key to decrease the set value, and press The SET key returns to the normal working state and the temperature setting is completed.
â‘¢When confirming that the value displayed by the instrument is not the correct measured value, the displayed value can be corrected. Press SET key for 3 seconds to enter the inner menu of the instrument. After selecting the parameter SC, cooperate with the â–³ or â–½ key to modify this parameter. The correction range of the sensor error is 50 to -50. After the correction is completed, press the SET button for 3 seconds to exit. The correction value is 0 when the meter leaves the factory. When using it, it is necessary to prevent the meter with the correct display from being corrected to be incorrect.
â‘£The auto-tuning function of the instrument: This product can adapt to most control systems. Only when the control effect is particularly unsatisfactory, the auto-tuning can be started. Press the SET key for 3 seconds to enter the inner menu of the instrument. Press the key to turn on auto-tuning. At this time, the At indicator starts to blink and the instrument enters the automatic tuning parameter working state. The instrument controls the heating system to fluctuate twice near the set point. When the At light is off, auto-tuning ends and the new PID parameters are locked in the chip in.
Classification:
1) According to the vibration method: gyroscopic (laboratory), reciprocating, dual function (gyroscopic and reciprocating)2) According to the assembly, it is divided into water bath, gas bath and oil bath gas bath thermostatic shaker: it is a biochemical instrument with a temperature controllable constant temperature gas box and oscillator. The water bath thermostatic shaker is a temperature controllable water bath The oil bath thermostatic shaker combined with the vibrator is a temperature-controlled oil bath tank and oscillator. The temperature control of the gas bath shaker is up to 70 ° C, and the common temperature is 37 ° C.
The temperature control of the water bath shaker can reach up to 100 ° C
3) According to the oscillation frequency:
There are three common types: 30-200RPM 400-300RPM 60-400RPM
Among them, the oscillation frequency reaches 400RPM, because the oscillation frequency is relatively large, so the requirements for the Erlenmeyer flask are high 4) According to volume: micro, constant and large 5) According to constant temperature range: low temperature (5-50 ℃) and normal temperature and high temperature 6) Divided by the number of layers: single layer and double layer 7) Divided by the number of doors: single door and double door 8) Divided by the display method: digital display (only numbers can be displayed) and LCD display (display numbers and letters)
9) According to the timing function: timing and normally open 10) According to the placement method: vertical, desktop, stacked., Floor type 11) Whether environmental protection is divided: fluorine and fluorine-free 12) According to heating power: 999W or less, 1000W-1999W; above 2000W 13) According to the oscillation amplitude: Φ25mm (commonly used), Φ50mm (large)
14) According to the use of power: 220V 50HZ 240V 50 / 60Hz (United States Thermo)
15) According to the driving mechanism: three-dimensional balanced eccentric wheel drive four-side slide bar driving mechanism 16) According to the compressor: imported and domestic, high-quality fully enclosed compressor and air-cooled sealed compressor 17) Amplitude adjustment method: multi-stage adjustable without Level Adjustable Shanghai Haozhuang Instrument Co., Ltd. is a technologically innovative high-tech enterprise based in Shanghai and radiating the whole country. The company has first-class technicians and a good team of technicians, with advanced technology and strong development strength. The company relies on Modern science and technology, constantly improving product quality and launching new products to keep it in sync with the international level, products are exported to all parts of the country, and won the trust of users with excellent quality and perfect service.
