Overview

The GTI aerosol photometer 3991 is a scientifically designed light scattering linear digital aerosol photometer, which is a testing instrument necessary for detecting the integrity or leakage test of high-efficiency filters. Compact structure, easy to carry, and can be operated and set up. The GTI aerosol photometer 3991 filter sealing tester features an 8.4-inch color touch screen with user-friendly interfaces. Due to its aerosol noise suppression function, the test data is more stable.

Product Details

GTI Aerosol Spectrophotometer 3991 Filter Sealing Tester

The scanning probe is connected to the 3991 body through a 4-meter-long pipeline, which not only has the same operation function as the body and synchronous display, but also has one-dimensional code scanning function. After scanning the one-dimensional code of the high-efficiency filter under test, the test data is automatically identified and classified, and the data is traceable, which facilitates the statistical analysis of the test data and improves work efficiency.

Color touch screen display, user-friendly interface in both Chinese and English

The product adopts an 8.4-inch color touch screen display, with switching between Chinese and English, rich options, reasonable design, and convenient operation. It contains options such as testing, settings, users, logs, data, about, suppression coefficient, alarm limit, report mode, date and time, all of which can be intelligently set.

Multi functional scanning probe

The scanning probe is connected to the host through a 4m long pipeline, and various options can be set even when far away from the host. The 1.8-inch color display screen synchronizes with the host. The scanning probe has one-dimensional code scanning function, automatic data classification and traceability.

enhancement

The upstream aerosol concentration is displayed as the actual mass concentration value ug/L. The product has noise suppression function, which can avoid the impact caused by unstable aerosol concentration values.

Third level permission management

The instrument has built-in GMP three-level management permissions, allowing for the free setting of 100 roles and allocation of operational permissions. And generate log reports for the operation.

Built-in lithium battery

Equipped with a large capacity rechargeable lithium battery, it can be used continuously for 4.5 hours. At the same time, it is equipped with a low-power mode to reduce instrument power consumption when not in use for testing. Improve battery usage time.

Performance guarantee

Equipped with a flow monitoring device and a sampling pump with adjustable pulse width, ensuring good operation in different locations and altitudes. Design scientifically and comply with electrical safety requirements.

Built in thermal printer

Equipped with a built-in thermal printer and long-lasting thermal printing paper for real-time printing. The product has a USB communication interface that can be connected to a computer to enable the transfer, storage, and statistical analysis of test data.

After the high-efficiency filter is put into operation, if there are leakage points or gaps due to insufficient installation, the predetermined purification effect cannot be achieved, and a leak test must be conducted on the high-efficiency filter. Due to the low concentration of atmospheric dust upstream of the tested high-efficiency filter, an aerosol generator needs to be used to supplement the dust to meet the testing conditions. By using an aerosol photometer to test the concentration of suspended particles upstream of the high-efficiency filter and conducting a uniform scanning test downstream, the leakage rate of the tested high-efficiency filter can be determined, which facilitates the identification and quantification of leakage points and provides reference for repair.
