Hydrogen Peroxide Detector-Portable H2O2 Detector-Hydrogen Peroxide Meter,Gas Detsctor[ONETEST]

EST-101-H2O2 hydrogen peroxide detector is a portable gas concentration measuring instrument. It adopts high-precision circuit design. The core adopts imported sensor chip. After Wanji Technology develops calibration, signal amplification, calibration calibration and strict testing, it is delivered to the factory.
The instrument is designed and produced in accordance with relevant national standards:
GB/T18883-2002
GB3095-1996
GB50325-2010
GB50325-2001
GB12358-2006
Mainly used:
Disease Control Medical Hydrogen peroxide is used as a bactericide, disinfectant, and oxidant for the production of pesticides and antibacterial agents. Daily disinfection is medical hydrogen peroxide, medical hydrogen peroxide can kill intestinal pathogenic bacteria, pyogenic cocci, pathogenic yeast, generally used for surface disinfection of objects.
Chemical industry The chemical industry is used as a raw material for the production of sodium perborate, sodium percarbonate, peracetic acid, sodium chlorite, thiourea peroxide, etc., oxidizing agents such as tartaric acid and vitamins. Removal of iron and other heavy metals when used to produce metal salts or other compounds. Also used in electroplating baths to remove inorganic impurities and improve the quality of the plated parts. Also used for bleaching wool, raw silk, ivory, pulp, fat, etc.
Food Industry The maximum allowable amount of food additives is the maximum allowable residue measurement. Hydrogen peroxide is a processing aid for the food industry. It should generally be removed before the final product is made. Except for the residual amount in the specified food.

Features:
High quality sensor for stable and reliable performance.
External power supply DC5V, built-in rechargeable battery.
Intelligent design, automatic detection at startup, no operation, zero calibration is convenient.
It has the function of restoring factory settings to prevent misoperation.
Supports ppm and mg/m3 unit conversion.
Configuration method LCD liquid crystal display technology, can display gas type, unit, concentration value, 1 hour and 8 hour average, date and time.
The instrument has a weighted concentration value viewing function for 1 hour, 8 hours, and time period, which is in line with the national indoor air quality testing standard.
With alarm function, it can set high and low alarm value, two-level sound and light alarm, and two high-brightness LED lights remind users to pay attention when alarming.
The instrument is small and light, and can be easily placed in a pocket or bag.
ISO9001 quality certification, ISO14001 environmental system certification, can pass the national measurement certification.
Optional sampling pump for safe measurement of closed spaces such as pipes, tunnels and test chambers.
