The light box is a kind of incubator, and there are artificial climate boxes, seed germination boxes and so on. Incubators provide the most suitable environment for plant growth, unlike the natural environment. The light box is a device that is mainly used for adjusting the light intensity, and it can also control the temperature and the time interval between day and night. The light box produced by Top Instrument is designed according to the “International Seed Inspection Regulations of 1993†and produced in accordance with the relevant requirements of the national industry standard JB/T6823 “Technical conditions of biological artificial weather boxâ€. Full compliance with various national requirements, it is now widely used in seed germination, nursery, microbial culture, insects and small animals. The light box is fully controlled by a microcomputer, with adjustable lighting, hot and cold temperature, and automatic switching functions day and night. While the seed germination box is sometimes used in conjunction with the seed wind instrument or seed blower and other instruments, they jointly serve the seed inspection service.
The light incubator produced by Top Instruments has a lot of capacity. For example, the minimum is 150L, ​​and the largest is 1000L. In the purchase process, we have to choose the right cabinet size according to our own needs. If it is too large or too small, it is not conducive to the full use of resources. The light box produced by Top Instrument mainly consists of a top cover, a studio, a cooling and heating room, and a bottom chamber. Each part can do its best, and then they are combined to serve the light box. The light box body has a liquid crystal panel and displays various information inside the box in real time. Therefore, the panel is provided with a plurality of keys. These keys have their own functions. The following is a description of the key functions of the light box.
AL: Over temperature alarm. When PV>SP+AL, there is cooling output. The parameter range is 0.0~60.0(1.5)°C. Outside this range, the system automatically alarms; ct: Compressor start delay, Compressor delay protection time, Two start time >= ct minutes, Start delay time range is 0 ~10Min; Pb: zero adjustment, Pb = mercury thermometer reading - current temperature measurement, zero adjustment range -19.9 ~ 60.0 (0) °C; PK: full adjustment, when the actual temperature deviation, adjustable The parameter value is corrected. PK=1000*(mercury thermometer reading value - current temperature measurement value)/ current temperature measurement value, full scale adjustment range is -199~999(0); uP: when the temperature rises, this parameter can control the compressor advance opening, ie PV When >=SP+uP, and the delay time is greater than ct, there is cooling output and the output light is always on. Only valid when the ALM lamp is flashing. The parameter is 1.0~1.0 (0.4); dn: cooling and cooling difference, when the temperature is lowered, this parameter can control the compressor to close early, that is when PV<SP+dn, close the cooling output. Only works when the ALM lamp is flashing.
