Roken-style mask fitting tester "MT-05U type"

Roken-style mask fitting tester "MT-05U type"

Before starting work, let's check the condition of the equipment in environments where harmful substances or large amounts of dust are present!

The "MT-05U model" comes standard with a testing guide and is a mask fitting tester that allows for simple leakage rate measurements without making holes in the mask. By changing the settings on the fit test mode screen, it can be made compatible with JIS T8150:2021 (for units equipped with JIS T8150:2006). Please use it in industrial workplaces where indoor tasks such as metal arc welding are continuously performed, or in workplaces that manufacture or handle indium compounds. 【Features】 ■ Labor Research Institute style ■ Compliant with Japanese Industrial Standards (JIS) T8150:2021 ■ Allows for simple leakage rate measurements without making holes in the mask *For more details, please refer to the PDF document or feel free to contact us.

Roken-style mask fitting tester "MT-05 type"

Roken-style mask fitting tester "MT-05 type"

It is a device that determines the rate of dust intrusion into the mask based on the dust concentration inside and outside.

The "MT-05 type" is a device that determines the dust penetration rate (leakage rate %) into the mask by measuring the dust concentration on the outside and inside of a mask worn by an individual. It tests the daily wearing condition of the selected mask in fit check mode. The test uses airborne dust from general indoor environments. For those who are already using a mask, it can be used to assess the selection and suitability of the mask. 【Usage Examples】 ■ Selection of N95 masks or similar that fit one's face ■ Educational guidance on proper mask wearing techniques ■ Measurement of the protection factor of respiratory protective equipment used in handling environments such as indium and refractory ceramic fibers ■ Fit check of the mask before entering the worksite while wearing the mask *For more details, please refer to the PDF document or feel free to contact us.

Roken-type Mask Fitting Tester MT-05U

Roken-type Mask Fitting Tester MT-05U

It is a measuring device that measures dust particles on the inside and outside of the mask and calculates the dust intrusion rate to the user based on the results.

Starting from April 2023, it will be mandatory for businesses that continue to conduct indoor operations such as metal arc welding to confirm that respiratory protective equipment is properly fitted (fit testing). The MT-05U model falls under this requirement, and currently, production is lagging, resulting in delays. Prompt consideration is necessary.

Mask Fitting Tester MT-03 Rental

Mask Fitting Tester MT-03 Rental

Ideal for selecting masks and confirming/instructing on proper mask wearing!

The mask fitting tester is a portable device that quantitatively checks the fit of dust masks on the face in various work environments and medical settings within one minute. It is effective for preventing dust exposure in occupational health settings and for air and droplet infection control in medical environments. Using a single detector (particle counter), it automatically switches between measuring the particle count inside the mask and outside in the room for continuous measurement. This reduces errors caused by differences in the characteristics of the detectors. 【Features】 - Measures the fit of dust masks on the face - Can be measured without modifying the mask - Capable of measuring N95 respirators (N95 masks) - Includes a heating element to prevent condensation of water vapor in exhaled air, which can lead to droplet formation - Equipped with RS-232C output function for measurement data For more details, please contact us.

Roken-style mask fitting tester "MT-05U type"

Roken-style mask fitting tester "MT-05U type"

Measure the number of particles indoors and inside the mask alternately with a single detector! Quantify the mask's adherence to the face.

The "MT-05U model" is a measuring device that counts the number of dust particles on both the outside and inside of a mask, and calculates the dust intrusion rate (leakage rate [%]) into the mask based on the results. It is equipped with three modes: fit test mode, fit check mode, and training mode, allowing for differentiation based on usage. Additionally, with the included mirror, the leakage rate (%) can be measured while confirming the fit of the mask. 【Features】 ■ Alternately measures particle counts inside the mask and in the room with a single detector ■ Quantifies the mask's adherence to the face ■ Allows measurements using a test guide and a tube joint set ■ Automatic recording function for measurement results ■ Leakage rate can be measured while checking the fit of the mask with the included mirror *For more details, please refer to the PDF document or feel free to contact us.

Mask Fitting Tester Series

Mask Fitting Tester Series

A device to check the fit of a mask on the face! Daily checks with a fit check.

We would like to introduce our "Mask Fitting Tester Series." This measuring device measures the concentration of dust particles on both the outside and inside of the mask, and from the results, it calculates the dust penetration rate (leakage rate (%)) into the mask or the fit factor indicating the cleanliness inside the mask. We offer two models: the "MT-11D," which uses a Condensation Nuclei Counter (CNC), and the "MT-05U," which employs a light scattering method (OPC). 【Features of MT-11D】 - Uses high-purity isopropyl alcohol (IPA) or ethanol for measurements. - Capable of conducting quantitative fit tests and shortened quantitative fit tests according to JIS T8150:2021 standards, and compliant with ISO and US OSHA standards. - Allows registration of subject and mask information independently on the main unit, in addition to communication software. - Screen operation can be performed using commercially available mice, in addition to the included touch pen. - Equipped with a classifier (DMA), making it suitable for measuring disposable dust masks DS2 and N95 masks. *For more details, please download the PDF or feel free to contact us.
