2020 is an unusual year for us because of the spread of the coronavirus, people are paying more and more attention to sterilization. As the virus spread, the coronavirus gradually spread to other countries. It is reported in the news that some countries use UV robots to sterilize some public places.

In fact, the UV germicidal lamp robot is nothing more than installing the UV germicidal lamp inside the intelligent robot. And then letting the robot sterilize the place where it needs to be disinfected. So how can we ensure that UV sterilization is effective? We can judge mainly from the following aspects.

1.Types of UV

Ultraviolet rays are divided into UVA, UVB and UVC. UVA is ultraviolet light having a wavelength of 315 to 340 nm, UVB is ultraviolet light having a wavelength of 280 to 320 nm. And UVC is ultraviolet light having a wavelength of 200 to 280 nm (nanometer). What can really sterilize is the UVC band.

2.UV band

Among UVC with a wavelength of 200 to 280 nm, the UVC germicidal lamp at 253.7 nm has the strongest sterilization effect. Therefore, a professional UV lamp intensity meter must be able to detect the intensity of UV rays with 253.7≈254nm.

3. Is the irradiation time enough?

While paying attention to the irradiation time, the energy intensity value of UV is a data that cannot be ignored. If the energy intensity value of the UV lamp reaches the standard, then the virus can be killed by standard time. If the energy intensity value of ultraviolet rays does not meet the standards, then we need to increase the irradiation time to achieve the purpose of sterilization.

If the above standards are not met, then the ultraviolet rays will not be able to achieve a good sterilization effect. We know that viruses generally have a good ability to reproduce and repair themselves. If the bacteria or virus is killed, the virus will be intact after a period of time. So whether it is UV lamp sterilization or UV robot, the UV energy and irradiation time must meet the standards. So we need to use UV lamp intensity meter to detect ultraviolet rays.

Linshang LS126C UV lamp intensity meter is a professional instrument for germicidal lamp detection. This uv lamp intensity meter is specially used to measure the UV-C wavelength, the spectral response range is 230nm-280nm and the peak wavelength is 254nm. LS126C uv lamp intensity meter not only can measure the real-time power value, but also the maximum, minimum, measurement duration and other measurement data. The fucntion is very comprehensive. The important point is that this instrument also has a Bluetooth function. After connecting to the mobile phone APP, unattended measurement can be realized. The human can avoid direct contact with UV rays. Avoid ultraviolet rays causing harm to the human body, making ultraviolet measurement safe and convenient!
