Stage Scissor Lift Table telescopic stage adopts an effective guiding system to make the gap between the telescopic stage and the fixed stage small in the process of translation, stable operation and stepless speed change. The synchronous device is driven by low-speed and large torque, so that the stage is absolutely parallel, free and retracted in place during the expansion and contraction process, and the leveling can be realized automatically. It is suitable for cultural and entertainment places such as auditoriums, cinemas, multi-function halls, studios, cultural stadiums and hotels.

Electrothermal temperature incubator calibration technical requirements,
Check cycle: once a week.
In the use of electrothermal thermostat incubators and repaired microbial incubators, the appearance of defects does not affect the normal work.
The thermostatic incubator should have the manufacturer's name, model number and factory number, the temperature display is clear, and there is no loosening of the knobs.
Temperature uniformity: no more than ±1°C at the test temperature.
Temperature indication error: no more than ±1°C at the test temperature.
Electric constant temperature incubator check conditions:
a. Mercury thermometer 100 °C (accuracy 0.2 °C) three.
b. Beaker 250mL three electrothermal incubators calibration items and calibration methods:
1. Appearance This check is performed visually and manually, and should meet the above technical requirements.
2. Temperature uniformity, three thermometers were respectively inserted into a beaker filled with 150 ml of water, placed in different places in the biochemical incubator that had been stabilized at the experimental temperature, and thermometer readings in the beaker were read after 5 hours with uniform temperature. Sex TR = Tmax (highest indication) - Tmin (lowest indication).
3. Temperature indication error, read the temperature indication of the biochemical incubator, and continue for two times, taking the average value T (displayed value), T (displayed value) and the average temperature value measured by the three thermometers in Section 4.2. The difference between T (test value) is temperature indication error.
In summary, the electrothermal constant temperature incubator has passed the verification result and is qualified, and is recorded. If it fails, it is deactivated and contacted for maintenance.
The lifting stage can realize the lifting and lowering of the double deck table. According to the needs, it can also be assembled into ladder shaped, multi scene and multi-level stairs to form a lifting platform group. It can form different steps within the travel range to enrich the multi-functional effect of the stage
The telescopic stage is suitable for the equipment of auditorium, theater, multi-function hall, studio, cultural stadium, etc. the telescopic stage adopts an effective guiding system, so that the gap between the telescopic stage and the fixed stage is small in the process of translation, the operation is stable and the speed is stepless. The synchronous device and the electric device are low-speed and large torque drive devices, and the telescopic stage is absolutely parallel, free, telescopic in place, and can automatically realize leveling
The rotating stage has various functions such as lifting, rotating and tilting. The control adopts self-locking, interlocking, travel switch, mechanical limit, hydraulic explosion-proof and other protection measures. To make the stage safe, stable and reliable, it is widely used in cultural and entertainment places such as auditorium, theater, multi-function hall, studio, cultural stadium and hotel.
Calibration cycle and method on electric constant temperature incubator
In the process of microbial cultivation, the use of electrothermal thermostat incubator is indispensable. There are still many places for its inspection method is not very clear, then the following detailed understanding of this issue.
