Fluke VT02 Visual IR Thermometer is the first IR thermometer to bridge the gap between digital thermometer and thermal imager. Blending a visual and thermal image of the targeted area allows you to see where the temperature is and pinpoint the problem without a lot of guess work.

Now, instead of the tedious tasks of taking and recording multiple, individual temperature readings, you get the complete picture with a blended visual and thermal image of your target area. The Fluke VT02 strikes the perfect balance between performance and affordability. Learn more...

Hello everyone. Today I am going to be putting the spotlight on the lowly, under appreciated chimney sweep brush. In particular, I want to discuss the various styles of brushes and the applications they would be used for.

First, lets talk about size. Brushes need a diameter that is larger than the diameter of the chimney that is being cleaned, with ideal size being between 1-2" above chimney diameter. This allows the brush to do its work with little need for side to side movement and ensures soot removal is at a maximum.

When it comes to brush styles there are two main categories, Stainless Steel and Fiber. Stainless Steel comes as a Crimped wire or a Flat wire, while Fiber has Perlon and PEK.

Stainless Steel Crimped Wire is a softer steel brush that can be used in all chimney types for soft to medium soot

Stainless Steel Flat Wire is a more solid steel brush that cleans harder deposits found in masonry and tile chimneys.

Perlon Fiber brushes are black plastic fibers that can handle light condition sweeping for stainless steel chimneys. Perlon fibers have a heat tolerance up to 122 °F.

PEK Fibers are a high tech synthetic fiber that handles light condition sweeping of stainless steel chimneys, ducts or pellet stoves. PEK fibers have a heat tolerance up to 300 °F.

Here at Valuetesters we carry the Wohler line of chimney brushes. Not only does Wohler make a great line of Chimney Cleaning Tools with the Viper series, it backs them up with quality brushes. Wohler has been a staple in the HVAC field for 75 years with its commitment to quality tools and service.

Poor air quality causes tiredness, inability to concentrate, and even illness.  IAQ monitoring and surveying especially for CO2 levels and air ventilation has become widely applied in public offices, classrooms, factories, hospitals, and hotels.  It is also recommended for regulating standards of industrial air quality in some countries.

UEi AQM4 Indoor Air Quality Meter features 4 in 1 measures of CO, CO2, temperature and RH.  This universal meter is unique, as it comes with CO sensor for added security of IAQ testing.
