Ar820 Formaldehyde Gas Detector

Formalin is a solution of formaldehyde gas dissolved in water. Formaldehyde is a colorless, strong-smelling gas that is commonly used in a liquid form, as formalin, for various industrial applications. Here are some key points about formalin:
Chemical Composition: Formalin is typically a 37% aqueous (water-based) solution of formaldehyde. The remaining percentage is water.
Uses:
Preservation: Formalin is widely used as a preservative for biological specimens. It helps to prevent decay and decomposition, making it essential in laboratories, museums, and medical facilities for preserving tissues and specimens.
Disinfectant: It has antimicrobial properties, and as such, formalin solutions are sometimes used as disinfectants and biocides.
Textile Industry: Formalin can be used in the textile industry for wrinkle-resistant finishes on fabrics.
Health and Safety Concerns:
Formalin is a strong irritant and can be harmful if inhaled, ingested, or comes into contact with the skin.
Prolonged or repeated exposure to formaldehyde can cause respiratory irritation and may be associated with certain health risks.
Proper ventilation and personal protective equipment are recommended when working with formalin.
Regulation:
Due to its potential health risks, the use and handling of formalin are subject to regulations and guidelines in many countries. These regulations aim to ensure safe practices and protect workers and the environment.

Product Introduction:


The handheld SF6 gas leak detector is a stable and sensitive leak detector. We have fully considered the actual needs of the majority of users, and at the same time apply our rich technology and experience to this product, allowing users to enjoy an excellent price-performance ratio.



The high-tech central microprocessor unit is the core of the qualitative leak detector for sulfur hexafluoride gas. Its digital signal processing capabilities can better manage circuits and process detection signals. Due to the use of a large number of integrated circuits, the number of components in the circuit is reduced by 40%, which greatly improves reliability and efficiency. The microprocessor can monitor the probe and battery voltage at a rate of 4000 times per second. Even the smallest signal can be captured. It can work stably and reliably in any environment.



The SF6 gas qualitative leak detector has added some convenient functions. Seven-level sensitivity, the sensitivity is increased by 64 times. The three-color LED gradually indicates the degree of leakage in a large range, and is also used to display the sensitivity level and battery power. Touch the keyboard to perform all operations. The avant-garde slender shape design greatly facilitates the user's use and maintenance. It is very convenient to use the indicator light in the direct range.
