Atmospheric pressure high and low oxygen environment simulation chamber

The controller adopts MS-51 series single-chip microcomputer, and the product of high and low pressure oxygen chamber is low in cost, practical and reliable. This high and low pressure oxygen chamber instrument combines the advantages of similar products in Germany, increases the input of high concentration oxygen, and greatly shortens the oxygen control time of the oxygen chamber compared with the past. In the intermittent working mode, the oxygen concentration rise curve is better, and the instrument has added four sets of time settings, which makes the change of experimental parameters more convenient. This instrument combines the past two products (intermittent hypobaric oxygen chamber, constant oxygen hypobaric chamber). One instrument serves two purposes. Ideal for simulating altitude in hypobaric and hypoxic training animal experiments.

5. Carbon dioxide controller (optional): range: 0-100%LEL, accuracy: 1%FS, response time ≤30S, can directly control the oxygen concentration and carbon dioxide concentration in the experimental box, and automatically proportion according to the set gas concentration gas to maintain a constant oxygen concentration environment. There is no need to mix proportional gases outside the box to ensure accurate experimental oxygen/CO2 concentrations and save gas sources

6. Temperature display function Monitoring parameters: temperature, humidity, oxygen O2 concentration, carbon dioxide concentration, low temperature circulation function (optional)

7. Intermittent mode flow F1: upper limit of oxygen content (eg: 21% can be set) F2: lower limit of oxygen content (eg: 8.5% can be set) T1: nitrogen filling process time (eg: 1 minute can be set) Setting) T2: Hold process time (eg: 1 minute and 30 seconds can be set) T3: oxygen filling process time (eg: 1 minute can be set) T4: Hold process time (eg: 1 minute and 30 seconds can be set)

8. It has passed the national quality system certification, and the equipment has a national registered trademark.

9. The input of high-concentration oxygen has been increased, so that the oxygen control time of the oxygen warehouse is greatly shortened compared with the past. In the intermittent working mode, the oxygen concentration rising curve is better. The instrument adds four groups of time settings, which makes the change of experimental parameters more convenient. The instrument integrates the past two products (intermittent low-pressure oxygen chamber, constant Oxygen hypobaric chamber), one instrument has

Two uses. The simulated altitude in the hypobaric hypoxia training animal experiment is to realize the dynamic curve and data.

10. Non-dispersive infrared (NDIR) carbon dioxide sensor, measuring range: 0~20%, control accuracy: ±0.1%

11. Temperature detection: imported high-precision digital platinum resistance temperature sensor

12. Dynamic curve of oxygen concentration change, intuitively understand the process of oxygen concentration change

13. Automatic calibration of oxygen concentration: quickly calibrate the sensor through the controller

14. Humidity sensor and dehumidification design can effectively reduce the impact of water vapor produced by breathing on animals during animal experiments

15. Unique gas mixing and circulation mechanism to ensure uniform gas concentration in the box

16. High-performance solenoid valve, stable performance, long life, support customized space size, standard can accommodate 2 standard rat cages and 8 mouse cages, suitable for large mice, small dogs, monkeys and other animals.
