MT-05U Mask Fitting Tester

MT-05U Mask Fitting Tester When wearing a dust protection mask, you need to select a mask that suits your face and wear it properly!! What is a Fit Test? A test, for selecting a mask that fits an individual's face, is called a Fit Test. The MT-05U can perform this fit test quantitatively. Differences from previous MT-05 model ● Daily check mode added ● Condensation reduction feature 　enhanced ● PC communication capability added ● Soft case included as standard ● Particle generator available 　(option) What is a Fit Check? When you use a mask selected in a Fit Test, the routine check to ensure that the mask fits well each day, is called a Fit Check. The MT-05U can perform the fit check quantitatively.

What is a Mask Fitting Tester? Important points when wearing a mask ● A tester that counts the number of dust particles outside Make sure that the mask fits your face snugly and 　 and inside the mask, and obtains the penetration rate that you are not inhaling harmful dust or germs. 　 (leakage rate %) of dust into the mask. First, perform a Fit Test ● The tester uses the dust floating in the room or sodium 　 chloride particles generated by a particle generator The size and shape of everybody's face are (option) as test particles. We recommend that a particle different, and selecting a mask that suits each generator is used when the dust particle count is low. individual is important for protecting their health. The MT-05U can perform a quantitative Fit Test ● A test guide or tube joint set is used to measure the mask that helps to select a mask, which fits each 　 leakage rate. individual. Routine checks using Fit Check Count the number of dust particles inside the mask When using the selected mask each day, the Count the number of dust particles outside the mask wearer checks how well the mask fits before entering the workplace. The MT-05U Mask Fitting Tester Capabilities Before measurement using Selecting a mask that fits When you find a mask that When the mask does not fit Fit Test mode..... your face...... fits your face ...... well ......

This is a measurement mode This is a measurement mode In this measurement mode, the This mode checks whether for selecting a mask that matches that can perform a check in penetration rate of dust particles the number of particles in the shape of your face by 30 seconds at the shortest into the mask can be easily the measurement environment performing several specified using the test guide.

Fit Test This is a test to select a mask that (Example) In the case of the OSHA fits your face. 29 CFR 1910.134 standard Several types of specified exercises are performed during measurement, The following specified exercises are performed for one minute each (⑥ and the measurement results for for 15 seconds), and measurements each exercise and the overall result for each exercise are made. are acquired. In addition to the methods (protocols) described in the ①Normal breathing ⑤Talking Japanese Industrial Standard (JIS), ②Deep breathing ⑥Grimace③Shaking head side to side⑦Bending over protocols such as the US OSHA ④Moving head up and down⑧Normal breathing protocols are included. Basic Fit Check Procedure ① Put on the mask ② Insert the test guide, which is connected to the‘MASK’side, between the face and the mask ③ Check the fitting of the mask again. ④ Hold the test guide connected to the‘OUTSIDE’side near the face ⑤ Press ‘START’ button (measurement can be taken in 30 seconds at the shortest!) ⑥ The pass/fail result and numerical results (count and fit factor) are displayed on the screen. ⑦ If the check fails, re-check the fitting of the mask or replace the mask with a different type or size and make the measurement again ● Two Types of Measurement ■ Test Guide (non-destructive mask test) Because it does not require any processing such as opening a hole in the mask (non-destructive mask test), the wearer can enter the workplace directly with a mask whose fit has been confirmed. It is suitable for routine fit checks! ■ Tube Joint Set (open a mask hole) Fixing the tube directly to the mask (open a mask hole) reduces the risk of Test Guide the tube falling out of the mask during measurement. It is suitable for a Fit Test mode that involves body movement during measurement. Tube Joint Set ●Communication function between 　PC and MT-05U • The MT-05U can be controlled from a PC (up to 4 units can be connected simultaneously). • Information about a subject, who is being tested, and mask information Fit Test Report can be stored in a database. • The set up enables the recording, browsing, and printing, etc. of measurement results for each measurement mode. • Measurement results can be saved 　in CSV format and it is processed Step Exercise Duration(Sec.)

Features With a single detector (particle counter), MT-05U measures the Outside inlet Mask side inlet number of particles in the room (outside the mask) and inside the mask alternately to quantify how tightly the mask fits the face. As a result, errors due to differences in detector characteristics are reduced. There are four modes: Daily Check mode, Fit Test mode, Fit Check Exhaust mode, and Training mode, that enable a user to use according Heater Touch panel RS-232C output to the application. Measurements can be made using a test guide (non-destructive Control circuit USB mask test) or a tube joint set (open a mask hole). Solenoid Flowmeter valve START button Automatic recording function for measurement results (Daily Particle counter Check mode, Fit Test mode, and Fit Check mode). Needle MT-05U communicates with PC using a USB cable. valve Leakage rate can be measured while the fitting of the mask is Pump checked by using attached mirror.
