What are the precautions when using paper fumigation equipment?

HX-ZW03 paper fast fumigation display equipment is specially designed to display the latent fingerprints on paper, which can be completed without any chemical treatment. The biggest feature of this system is rapidity and non-damage. The introduction of this device is a revolutionary breakthrough in paper fingerprint display technology. After the fingerprint is displayed, the lines are clear and the contrast with the background is large, which is convenient for observation and taking pictures.

Without any chemical treatment, the latent fingerprints on paper can be quickly developed, and the development process can be completed within 15-60 seconds, which is especially suitable for the rapid processing of a large number of samples. According to different types of paper, the display conditions can be flexibly set to obtain the best display effect, prevent cross infection, be safer and more unique for the sample, ensure the safety of the sample, and display the old fingerprints (up to one year). And it will not weaken the equipment with the passage of time after it appears. After it appears, you can continue to use ninhydrin, DFO or physical developer for treatment. The whole system has the functions of showing, observing, taking photos or further processing with DCS4 fingerprint inspection workstation. Maximum supported paper size: 240 x 320 mm Single occurrence time (depending on paper type): 15 ~ 60 seconds. The working voltage of the equipment is 220V/50Hz. The maximum suitable paper size is 3 10*230mm, and the stepping speed is 25-650CM/ min, increasing or decreasing at 625px/ min.

Temperature adjustable range 90- 165℃ power adjustable range 40-99%, plus or minus 50%. The number of pallet trips is 1-5. Fingerprints appear in 20 seconds to 5 minutes. Product size: 390*463*260 Features: Touch screen technology can be used to adjust different temperatures, fumigation times and speeds, aiming at handprints on A4 paper, envelopes, newspapers, post-it notes, napkins, carbon paper and UnionPay cards. At the same time, you can choose a portable laser material evidence finder to quickly find fingerprints. In order to use the instrument correctly, we must understand the general rules and common sense in the instrument. If you don't follow these rules, you won't necessarily lead to mistakes, but you will get obviously wrong results in some occasions or in some cases. This often makes people feel that the rules or common sense in these measurements are not so strict or so useful, especially for students with insufficient practical experience.
