Today I am reviewing the MF100 AC/DC Magnetic Field Meter from Extech. The MF100’s primary function is to measure both AC and DC magnetic fields in gauss and mT (milli Tesla) via an advanced uniaxial Hall effect sensor with automatic temperature compensation.

Lots of changes have made their way into the HVAC Industry with the latest being the shrinking size of the recovery machine. Yellow Jacket has released their own version with the Yellow Jacket 95730 YJ-LTE Refrigerant Recovery Machine. This unit is hailed by Yellow Jacket as the smallest, lightest, and most powerful unit in its class. The YJ-LTE can be used with Vapor, Liquid, and standard push/pull and weighs in at a lowly 24 pounds. The oil-less compressor packs ½ HP with twin cylinders and has a high pressure shut off at 517 psi.

Is finding the moisture content of a roof or wall something that would be of use to your operation? Today’s review will help answer that question as we look at the Tramex RWS Moisture Content Detector.  This handheld scanner is really two of Tramex’s products built into one device. One half of the device is used to for roofing and the other half is for use on exterior walls. Let’s start with a quick explanation of how it operates.

Today I am reviewing the Tramex DEC Scanner DSAL Roof Moisture Detector. The Tramex DEC Scanner’s primary function is to continuously measure moisture content as the user pushes it across a roof. This design is more than twice as fast as nuclear meters, and provides instantaneous and clear indication of the roof condition. The Tramex DEC Scanner is very straightforward to use, and does not require any formal license or training.

Having poor grounding can lead to premature equipment failure and extended downtime which can be quite costly to a company’s operations. The handheld unit is lightweight (2.2lbs) features an easy to read display and has a simple to navigate menu system.
