PORTABLE AIR QUALITY METERS
Today there are many inexpensive portable meters to monitor indoor air quality that can accurately detect formaldehyde, HCHO, VOCs, PM2.5 / PM1.0 / PM10 temperature and humidity with air quality contamination tests.
Intelligent air quality monitors are easy to carry and help detect in situ and in a few seconds air concentrations in kitchens, hotels, restaurants, homes, offices, cars, hospitals, clinics, buses, trips, places of leisure, etc. A protection for the health in general. If it exceeds the standard, it alerts with an alarm.
PORTABLE METERS BACTERIOLOGICAL RESULTS
To obtain bacteriological results of the environments, there are measurements with the luminometer. These are made using the ATP test tubes. Check the surface with the cap included in the tube. The plug is pushed to the bottom of the tube so that it comes in contact with the reactive liquid and the reagent itself. With slight agitation, the reactive liquid is collected in the reaction chamber of the tube.
This technology has made great advances in the last decade and has been increasingly adopted as a tool for hygiene verification, since it can be used during food processing. This test is based on the detection of organic matter-ATP (adenosine triphosphate), which will be present in all living cells. It also exceeds traditional microbiological methods in time.
The effectiveness of hygiene has traditionally been evaluated through microbiology tests in which swabs, sponges or contact plates are commonly used for sampling. These tests only provide information regarding the load of microorganisms present in a surface, having as a major limitation the response times, since incubation periods are required that vary from 24 to 72 hours, to obtain results on the hygiene of the surfaces. This is not very convenient since it does not have the possibility of guaranteeing the quality and safety of the processes, as well as being able to carry out corrective actions.
This test is based on the detection of organic matter-ATP (adenosine triphosphate), which will be present in all living cells. The test measures both the ATP from food waste as well as that of microorganisms in surfaces and liquid samples. The monitoring is carried out at critical points in the production line or in rinse water in CIP type cleaning systems where, in the presence of ATP, the luciferase enzyme catalyzes a reaction in which the final product is light. This light is measured using a luminometer, whose unit of measurement is known as Relative Light Units (URL), not being a standardized unit that depends on the bioluminescence equipment used.
BLUE METHYLENE DEGRADATION TEST
The efficiency of our une2 product for photocatalysis can also be measured directly by the degradation of methylene blue, rhodamine B or other organic dyes such as coffee. The products of photocatalysts can be measured simply. Take two plastic cups, add two thirds of the photocatalyst solution to one and add a few drops of colored substances, such as red ink, dye solution, coffee, etc., and divide the color solution obtained in two. Half is placed in a place where there is no light, such as a drawer or a closet. After a few hours, it is removed and compared with half the solution placed in a light spot in the room. If the solution of the previous one fades, it is a good photocatalyst. If there is no change, it will be an inappropriate product. This experiment can be repeated many times because the photocatalyst acts as a catalyst and the catalyst is not consumed, so the photocatalyst is effective for a long time.
