A new probe capable of measuring relative humidity, dewpoint, absolute humidity, specific humidity, wet bulb temperature, and dry bulb temperature is available for the AdvancedSense HVAC/OH/FM/IAQ meters. The small-diameter probe may be directly connected to the AdvancedSense meters via the lower left 7 pin socket.

Now available with Bluetooth wireless communication, the portable BTU4400-NOx flue gas analyzer is designed for emissions monitoring, maintenance, and tuning of combustion processes. Its rugged design and “true NOx” capability makes the 4400 an ideal industrial analyzer for boiler, engine, furnace, and other combustion applications.

Two combustion analyzers, models 310 and 320, can be used by HVAC techs for residential tuning and commercial applications. The 310 is a residential analyzer designed to measure flue gas, draft, ambient CO, and pressure, while the 320 is for residential and commercial boiler/burner tune-ups, service, and maintenance.

The AB-100CS Acid-Buster™ Injection Kit is designed to bond with acids without forming chemical byproducts and prevents acid build-up in air conditioning and refrigeration systems. Use of the injector requires only one connection to add acid scavenging solution into the system.

A DVD titled “Minneapolis Blower Door™ Quick Guide” is available. A copy of the DVD is included free with the purchase of any Minneapolis Blower Door. Professionals use the blower door to measure the airtightness level of building envelopes, diagnose and demonstrate air leakage problems in buildings, and more.

Compact and lightweight, the Optimax™ 400 is a cordless, true UV LED leak detection flashlight that emits less visible light so refrigerant leaks are clearer and easier to spot, saving valuable inspection time, said the company. It features a high-output UV LED that causes dyes to fluoresce more brilliantly.

With four ports and a built-in vacuum gauge on the SMAN4 digital manifold, users can evacuate a system, pull a vacuum, add refrigerant, and dial in the charge without unhooking their manifold. There are three standard ¼-inch ports and one beefy 3/8-inch port with the bore in the manifold being 3/8 inch throughout.

The overall height of Weather Guard® Protect-A-Rail® cab protectors has been reduced to make them more compatible with current full-size truck model year designs. In turn, two mounting brackets have been modified to allow the cab protectors to be installed with the Ford F-250/F-350 Super Duty and the Dodge Ram.

The HVAC service cart’s workbench allows the technician to work from an upright position. With a mounted vise the technician can prefabricate piping on the cart, instead of working in awkward, hard-to-reach areas where injuries and fire may result, said the company.

Used in pairs, the Attic-Trax™ Walkboards help workers in the construction, HVAC, and electrical industries move safely through an attic space, while preventing ceiling damage and increasing productivity. The boards are constructed from durable, lightweight composites.
