Before testing the target environment, verify that the instrument is working properly. Perform the following steps in a clean environment:
The brake disc is composed of steel plate, adhesive heat insulation layer and friction block. The steel plate is applied to resist rust. In the painting process, smt-4 furnace temperature tracker is used to detect the temperature distribution in the coating process to guarantee the quality. The heat insulation layer is composed of non-heat transfer materials for the purpose of heat insulation. The friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc or brake drum to generate friction, so as to achieve the purpose of decelerating the brake. As a result of friction, the friction block will be worn gradually, generally speaking, the lower the cost of brake block wear faster.
Tower Crane Brake Disc is used for tower crane motors. To divide in function , there are hoisting brake disc, trolleying disc brake pad and slewing motor brake disc. Tower Crane Brake Disc is the easy wearing spare parts, therefore the quality of the Brake Disc is very important. BQ provides good quality Brake Disc, which is composed of steel plate, adhesive heat insulation layer and friction block. The steel plate is applied to resist rust.

TN800 formaldehyde monitor operation procedure
TN800 Formaldehyde Monitor Operating Procedures To better use the instrument, read the instructions carefully before use. Before the test, the instrument can reasonably grasp the warm-up time. For example , if you have not used before more than 2 hours, if you require a higher result, it is recommended that you warm up for 15 minutes. If the power is less than 40% , it is recommended to charge it for emergency use. This instrument is equipped with a Teflon sampling tube. If the dust is very large, it is recommended to use a sampling tube with a dust filter inserted into the air inlet (left gas nozzle), otherwise it is not recommended to use a sampling tube with a filter; The vent can decide whether to connect the trachea according to the situation. After the detection of toxic and harmful gases, it must be in a clean environment, and then enter the detection mode for a gas detection, until the concentration of toxic and harmful gases return to 0ppm , and lasts more than 1 minute, and then shut down into the instrument box. The ideal working temperature of most sensors is 20 degrees Celsius, so when used in a low temperature environment, the sensor response will be slower than usual, especially semiconductors such as odors, they require a long warm-up time, need to maintain a certain temperature Only accurate detection can be performed. Under high humidity conditions (greater than 65% RH ), the signal of the sensor is usually too large.
