The PVC Granulating Production Line is mainly consisted by the following equipment: Conical twin screw extruder, die-face hot cutter mold, face cutting system, air blowing system etc.
Usage: This recycling production line is the best choice for recycling waste plastics like PVC materials.
Varies models for your capacity needs.

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.
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.
