Environment Meter
Overview
The MT941 5-in-1 digital Multifunction Environment Meter has been designed to combine the functions of a Sound Level Meter, Light Meter, Humidity Meter, Temperature Meter and CFM/CMM Thermo-Anemometer. It is an ideal Multifunction Environment Meter with scores of practical applications for professional and home use. The Sound level function can be used to measure noise in factories, schools, offices, homes, checking acoustics of studios, auditoriums and hi-fi installations, etc . The Light function is used to measure luminance in the field. It is fully cosine corrected for the angular incidence of light. The light sensitive component used in the meter is a very stable, long life, silicon diode. The Humidity/Temperature uses a humidity/semiconductor sensor and K-type thermocouple. CFM/CMM Thermo-Anemometer is suitable for use in a wide variety of applications, including plant maintenance operations, environmental analysis, fume hood testing, and HVAC system assessments.
Features
- Large LCD display with backlight
- MAX, MIN and AVG measurements
- Display shows Sound, Light, K-Type Temperature, Humidity & Temperature as well as Air Velocity & Air Flow
- Electronic Offset function allows compensation of thermocouple errors to maximize overall accuracy
- The device measures air velocity, it features 5 selectable units of velocity measure: m/s, ft/min, km/h, MPH, knots, and it features 2 selectable units of flow measure: CFM, CMM
- Easy to set Area dimension (up to 6 points) for air flow measurement
- USB interface, USB to UART Bridge Controller
- Low battery indication, Auto Power Off (Sleep mode) adjustable
- Data Logging

Burn me once

Cheaply made, Irish pennants dangling from several places on the garment.

Short sleeve button down shirt
Size: XX-Large, Color: Navy Blue
These might run a size smaller. It still fit me but it is closer to XL than XXL in my case. It is great and comfortable as a casual shirt to wear out. It is easy to wash and dry, it did not shrink with cold water and just a tumble dry.

Comfortable, roomy fit and quality fabric
Size: Medium, Color: Flamingo, Size: Medium, Color: Flamingo
This is a comfortable, well-made guayabera (Cuban wedding-style shirt) available in a range of colors. It fits true to size on me, offering a little extra room to help you contend with the summer heat. The color and size hold up well in the wash; I've worn this shirt several times and it still looks great and hasn't suffered from any kind of shrinkage at all. I particularly like the linen blended with cotton here; linen is nice and light but can be too light sometimes and it wrinkles when you look at it, but the cotton balances it out nicely. The current discounted price of $20 a pop here is an absolute steal as well; I'm tempted to get another couple just to have some more options in my closet. Overall, I'm happy with this product.

Excellent dress shirt for the summertime!
Size: X-Large, Color: Navy Blue, Size: X-Large, Color: Navy Blue
This has rapidly become one of my top shirts to wear during the summertime, and it isn’t even summertime yet! Got this shirt in the other day and this shirt just checks all the boxes for me. It is comfortable in fact that it’s very comfortable. The material is not dry fit but it is not a material that will make you sweat the way cotton would make you sweat.. the fit is spot on, and it just happens to be one of those shirts (we all have shirts like this) where it is one of the go two shirts that you grab when you wanna look nice, yet you wanna be comfortable.
Another thing I like about this shirt is the collar it doesn’t stick out too far and it just seems to fit in place the right way. Some collar on some shirts rest too far outside of your neck and some hug along your neck line, this shirt does neither of the two, it just fits perfectly. The material is very breathable allowing this shirt to be worn in any nice weather climate whether that is warm, hot, or that very sticky humid hot..
Another great thing to point out is I have washed it twice already and it keeps its nice clean look to it and I have not really had to go crazy with the ironing. For the price I think it is aAnother great thing to point out is I have washed it twice already and it keeps it’s nice clean look to it and I have not really had to go crazy with the ironing. For the price I think it is a steal of a deal, yeah I wish I had a closet full of these shirts with other colors.
