Introduction to Guoyuhua incubator

Guoyuhua incubator has good quality, Jintanhua incubator is good, Changzhouhua incubator is good, Guoyuhua incubator introduction, Changzhouhua incubator retail, product introduction, digital display biochemical incubator has refrigeration and heating two-way temperature adjustment system, temperature The controllable function is an indispensable laboratory equipment for scientific research and teaching departments such as plants, organisms, microbial genetics, viruses, medicine, and environmental protection. It is widely used in constant temperature tests, culture tests, environmental tests, etc. Its main features: This product uses integrated circuit temperature control, digital display, intuitive and clear. The insulation material of the box is made of polyurethane on-site foamed plastic, which has strong anti-interference ability against external heat and cold sources. The inner wall is made of stainless steel molding process and has strong corrosion resistance. 2. Technical Parameters Model - B - Power supply cooling power Heating power 3 3 Temperature control range -℃ -℃ -℃ -℃ Temperature control accuracy ±.℃ ±.℃ ±.℃ ±.℃ Effective volume working time continuous continuous continuous 3. Instructions for use: The incubator should be placed in a dry, clean, well-used studio, away from heat sources and sunlight, and placed stably to prevent vibration and noise. , Before use, all control switches on the panel are in non-working status. Before placing each test bottle (or vessel) on the incubator rack, an appropriate distance should be maintained to facilitate the convection circulation of cold (hot) air. . This machine has a compressor protection function, that is, the compressor cannot be started continuously. When the compressor stops working, the protection light will be on, and the refrigeration device can be started only after 3 consecutive minutes. , Temperature setting: , Setting temperature: Press the button to set the temperature. Press the button once and the digital tube data in the lower row will flash (the upper row will measure the temperature normally). At this time, the meter will enter the temperature setting state. Press the △ button to increase the set value. Press the ▽ button to decrease the set value. Press the button again. Return to normal working state and temperature setting is completed. . Correction of sensor error: Press the button for 3 seconds to enter the inner menu of the instrument. After selecting the parameters, use the △ or ▽ key to correct the error. The display resolution is degrees. The correction range of the sensor error is ±., and the display resolution is degrees. The correction range is ± degrees. After completion, press the button for 3 seconds to exit. When the instrument leaves the factory, the correction value is. . Start self-tuning: This product can adapt to most control systems. Self-tuning can only be started when the control effect is particularly unsatisfactory. Method 1: After powering on the instrument, press the shift key for 3 seconds to start auto-tuning. Method 2: Press the button for 3 seconds to turn on auto-tuning. The indicator light flashes when the self-tuning is in progress. The process is that the instrument-controlled heating system fluctuates twice near the set point. When the indicator light goes out, the self-tuning ends and the new parameters are locked in the chip. . Refrigeration compressor delay protection: After the compressor completes one round of work, the pressure in the evaporator needs to be released through the capillary tube. During the pressure relief process, starting the compressor under pressure may damage the compressor. A delay of - seconds is required before the compressor starts again to protect the compressor. The parameter is the compressor restart delay protection time. . Intervention and separation of refrigeration control: When the set temperature is lower than a certain temperature point (parameter), the compressor must work continuously, and the system uses the energy consumption balance method to stabilize the temperature. When the set temperature is higher than a certain temperature point (parameter), the compressor does not need to participate in the work, and the system only needs to add temperature to stabilize the temperature. Setting of the instrument's working mode and description of each parameter (press the button for 3 seconds to enter the inner working parameters) Code parameter meaning description Setting range Default refrigeration start deviation Temperature control point of refrigeration start - full range. 3 Alarm parameters Temperature control of alarm relay action point - full range. Refrigeration delay time. Time for compressor to restart delay protection - seconds. Refrigeration will not stop when the temperature set by the refrigeration full-open point is lower than the full range. Refrigeration will not stop when the temperature set by the refrigeration full-off point is higher than the refrigeration full-off point. Not starting - full range 3. Refrigeration point hysteresis, refrigeration output action insensitive area - full range proportional band, if, it is position control. When the value is not , the instrument is proportional output control and has a dynamic working range. ℃-℃ Main output hysteresis main output action insensitive zone (occurs when) -℃. The integration time constant eliminates the static difference, and the instrument controls the intensity of the output energy. The smaller the value, the stronger the control ability. -Second differential time constant pre-adjusting ability, the speed of regulating the output energy when the measured value changes. The bigger the value, the quicker the response. -Second 3 The sum of the proportional cycle heating and termination time is one cycle. The meter controls the output power by adjusting heating and interruption - seconds 3 Measured value offset sensor error correction ±. Automatic adaptation The process by which the meter automatically selects the appropriate control parameters. Off/on proportional band offset is used to prevent temperature overshoot when the meter is first turned on. rush.
