Which alarm signal will be issued abnormally in the test chamber

Due to the special environmental requirements of the constant temperature and humidity test chamber, the staff of the test material had to master the “every move” in the box. Only in this way can the temperature or humidity inside the box be kept at a certain value. However, sometimes the temperature and humidity inside the box are too high to be noticeable to the human eye. So scientists installed an induction alarm system on the outside of the test chamber. When the abnormal condition occurs in the constant temperature and humidity test box, an alarm signal will be issued. What abnormalities in the test chamber will cause the alarm system to signal? The following force one by one for everyone to answer:

1: When the temperature inside the test chamber is too high, the sensing system will alarm. At this time, we should immediately cool the inside of the box. We must not open the door immediately to avoid burns.

2: When the fan of the test box is overheated or over-current, it will also give an alarm sound.

a: When the fan coil overheats, the equipment stops and alarms. We must resolve the fault to continue the test. Otherwise it is very dangerous.

b: When the fan current exceeds the allowable value, the equipment is stopped and alarmed. The equipment must be allowed to resume normal operation after over-current troubleshooting is completed.

3: Refrigeration, heating compressor overheat will alarm. Due to the long working hours, it may also be caused by the failure of the cooling and heating system that causes the compressor to heat up quickly. At this time, we must stop the test, check the place where the compressor is in trouble, and repair it in order to re Put into use.

4: Improper operator operation The alarm system of the test chamber will also remind. When the operator operates the test box system, the alarm will be set when the heating value or the humidification value is set too high. We should heat and humidify according to scientific values.

Mirror Acrylic Plexiglass Sheet

Acrylic mirror sheets
Lightweight, impact-resistant, shatter-resistant mirrored acrylic sheets are cheaper and more durable than glass. Flexibility makes it superior to glass, and the range of colors available makes it an ideal material for a variety of applications and industries. Applications you may not be considering include use in decorative furniture and cabinetry making, signage, POP/ retail/store fixtures, and display, decoration and interior design applications. Acrylic mirror panels can also be cut, drilled, shaped and thermoformed.

Cutting acrylic mirror plate
Measure and mark where you want to cut
Make a shallow cut in the paper with a carving knife
Place the acrylic mirror side up
Place the part with the shallow cut on the edge of the surface
Quickly and steadily bend the sheet so that it folds into a straight, clean edge.

Note: You can also purchase acrylic mirrors in cut sizes from us.

Acrylic mirror material
Acrylic mirrors are made of acrylic plastic. Through the vacuum metallization process, acrylic is constantly processed, so that the plastic has a mirror finish.

Can you bend an acrylic mirror?
Yes, acrylic mirrors can bend. The thinner an acrylic mirror is, the more elastic it is, but its elasticity is limited before it breaks. To further shape, acrylic mirrors can be cold bent into a curved shape, or heated to create a sharper bend.

Can acrylic mirrors deform?
Acrylic mirror we recommend to place it on a solid frame or surface, can avoid bending deformation.
