Lightbox performance parameters

Lightbox performance parameters

The light box is an incubator capable of providing a simulated natural environment in which light is considered and temperature and light time can be set. The light box is fully controlled by the microcomputer, with adjustable illumination, hot and cold constant temperature, and automatic switching function 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 box”. 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 also called an intelligent light incubator, because its control parameters have been implemented quite intelligently.

The light box has become an ideal test equipment for the production and research departments of biological genetic engineering, medicine, agriculture, forestry, environmental science, animal husbandry, and aquatic products. The box consists of four parts: the top cover, the studio, the cooling and heating room and the bottom room. The top cover is equipped with a computer controller, and the top cover panel is equipped with a digital display, indicator lights and operating switches. The two sides of the top cover are respectively equipped with fluorescent sockets, and the studio has three hollow glass structures. The cooling and heating are under the studio, and the left and right sides are respectively connected with the entrances and exits of the ventilation passages in the studio. The interior is equipped with an evaporator, an electric heater and two circulating fans to supply heat or cooling to the studio. The bottom chamber is equipped with compressors, condensers, cooling fans, instrument entry junction boxes and fuses.

The following are the meanings of some buttons of the light box, we do analysis one by one. 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 will automatically alarm; ct: Compressor start delay, Compressor delay protection time, Two start time >= ct minutes, Start delay time range is 0. ~10 (3) Min; Pb: zero adjustment, Pb = mercury thermometer reading - current temperature measurement, zero adjustment range -19.9~60.0(0) °C; PK: full-scale adjustment, when actual temperature deviation When this parameter value can be adjusted, it can be 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 heating up, this parameter can control the compressor to open in advance, ie PV When >=SP+uP, and the delay time is greater than ct, there is a 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.
