Tools were promoted as being easy and even comfortable to use. Test instruments reflected the ability of such products to do more functions at a faster pace.
Here then, in alphabetical order, is a look at the latest.
Amprobe (www.amprobe.com) released four new voltage and continuity testers, the VPC-10, VPC-10N, VPC-20, and VPC-20N, the latter two being digital voltage and continuity testers. The N models also offer noncontact capability.
The company also released five new clamp-on multimeters. ACD-6 Pro and ACD-6 TRMS Pro feature auto and manual range selection and data hold. ACDC-400 measures voltage up to 600 V, and AC/DC current up to 400 A. The ACD-14 and ACD-14 TRMS' dual display allows technicians to view amperage and voltage simultaneously.
The G5Twin is a recovery unit from Appion Inc. (www.appioninc.com) that uses an extra-heavy-duty crankcase for driving twin pistons. The twin cylinders are said to allow for greater throughput for both liquid and vapor pressure. The crankcase is isolated from the refrigerant flow, so the unit's main drive will last much longer because the bearings are not being washed in refrigerant, according to the manufacturer.
Bacharach (www.bacharach-inc.com) showed an improved version of its Stinger universal refrigerant recovery unit. A dual-valve compressor provides faster recovery rates, according to the company, and the unit is capable of pulling a vacuum for an extended period of time without damaging the compressor.
New vacuum pumps (part of the Pro-Set® line) were shown by CPS Products (www.cpsproducts.com). Dual-voltage de-signs operate on 115 or 230 VAC. The two-stage design pulls deep vacuums to 15 microns. The single-stage design quickly pulls a vacuum to 100 microns, the company said.
A Digital Refrigeration System Analyzer (DRSA) manufactured by Digi-Cool Industries Ltd. (www.digi-cool.com) was shown at the booth of Shook Manufactured Products (www.shookmfg.com). The DRSA includes superheat and subcooling display plus pressure max/min tracking. The unit's features are designed to make system commissioning, service, and diagnostics simpler, quicker, and more accurate, according to the companies.
Dillon Enterprises claims its Colorfullâ„¢ sight glass is designed to make it easier for techs to distinguish between an empty sight glass and one that is completely full. When the glass is empty, it is clear and works like a conventional sight glass. As it fills, it changes color.
"The change is so dramatic that it can been seen from several feet away, often without the need of a flashlight," the company said.
The company's new photo/contact tachometer (RPM10) includes a built-in, noncontact infrared thermometer with laser pointer that provides surface temperature measurements in locations that may be unsafe or hard to reach. Another new product is the RH520 humidity and temperature chart recorder, which provides simultaneous numerical and graphical displays of humidity (20 percent to 90 percent rh) and temperature (-20 degrees to 140 degrees F). The 1000A and 800A Series clamp meters include the former with a noncontact infrared thermometer and laser pointer to monitor temperature and locate hot spots.
Fluke (http://us.fluke.com) introduced the 983 Particle Counter, a compact test tool for IAQ work. It features expanded data logging and six-channel particle size display, allowing users to run more tests faster and spend less time cycling through screens to get the data they need, the company said. The tool's liquid crystal display includes a backlight.
The company also showed its 87V digital multimeter, capable of measuring voltage and frequency on adjustable-speed motor drive systems. It comes with a built-in thermometer and features large display digits and a bright white backlight for easier reading in low-light areas. The Fluke 430 Series three-phase, handheld power quality analyzers feature AutoTrending, which records everything on the screen automatically; and SystemMonitoring, a quick diagnosis of system performance against user-defined limits.
Inficon (www.inficon.com) introduced Vortex AC, which the company billed as the next-generation refrigerant recovery machine. An upgraded compressor has ceramic bearings for longer life and increased recovery rates; a single-valve, liquid-tolerant, oil-less compressor is driven by a 1/2-hp AC motor.
The company also introduced CO Check, a carbon monoxide meter for residential, commercial, and industrial applications designed for one-handed operation. Audible and visual alarms indicate the level of gas present.
The device was created to provide all of the key operating data a contractor may need to detect and diagnose developing problems before they cause a failure in equipment, the company said. The kit consists of a monitor with 10 sensors and six open sensor inputs, which is mounted on a customer's equipment and connected to a phone line.
Klein Tools reported that its Klein Tradesman Club helps keep members regularly informed of the latest developments in tool technology. Information is available at www.kleintradesmanclub.com.
A thermocouple temperature switch from Love Controls Dwyer Instruments (www.love-controls.com) helps monitor and control temperatures in heating-cooling applications. The Series TCS offers a wide temperature range, two selectable alarm sets, and an internal buzzer that indicates an alarm condition or error.
The AirMaster from Mannix (www.mannix-inst.com) is a digital airflow meter that measures cfm, Btu, temperature, humidity, dew point, and wet bulb. The WDCFM8951 has a small wind vane and long telephone-style cord.
A digital pressure-temperature chart from Mastercool (www.mastercool.com) is a compact, pocket-size device that provides pressure/temperature references on an LCD display. Readings are in psi, bar, and MPa for such refrigerants as R-12, -22, -134a, -401A, -402B, -404A, -410A, -500, -502, and -507.
Two new products from Meterman Test Tools (www.metermantesttools.com) are the EPM3 phase-sequence and motor-rotation tester, and the AC71 digital multimeter. The EPM3 tests three functions: open phase, phase sequence, and motor rotation. Half of the unit measures the phase sequence of a three-wire system using the power of the unit under test. Using lamp indicators, it shows the three-phase sequence or alternately indicate an open phase. The opposing half of the EPM3 verifies three-phase motor rotation (clockwise or counterclockwise) on an unpowered motor using an internal 9-V battery.
The AC71 DMM is a clamp-style meter employing AutoTectâ„¢ plus an automatic backlight. The AutoTect feature automatically senses what type of measurement is being made when test leads are placed across a measurement point. With no knobs to turn, the meter automatically senses what is being tested and displays the measured valve along with the associated unit icon.
Quart and gallon package sizes are now being offered by Nu-Calgon (www.nucalgon.com) for its Zerol Ice compressor lubricant. The product is designed to enhance the lubricity of the oil, reducing friction drag in the compressor.
Onset Computer Corp. (www.onsetcomp.com) introduced the HOBO U9 light on/off logger, a compact, direct-USB data logger for recording light usage. Designed for energy service contractors, facility managers, and others who need to analyze light usage patterns in commercial and institutional buildings, the logger performs around-the-clock monitoring of light on/off status.
Promax (www.provaxac.com) showed the ProVax, a portable A/C service system that combines a high-end oilless refrigerant recovery unit with a vacuum pump. It can recover all refrigerants, the company said. The unit uses a 1/2-hp motor to drive the recovery and evacuation processes.

Setra (www.setra.com) showed its Systems 260 pressure transducers that sense differential or gauge (static) pressure and convert this pressure difference to a proportional electrical output for either unidirectional or bidirectional pressure ranges (field selectable).
The Optimaxâ„¢ portable fluorescent leak detector from Spectronics Corp. (www.spectroline.com) is said to pinpoint all refrigerant leaks. The product uses LED technology to deliver 10 times brighter leak detection light than regular LED lights, the company said.
In addition, two new EZ-Jectâ„¢ dye injection kits feature the EX-50 dye-injector assembly, an A/C hose assembly with check valve, a 1/4-inch flare fitting, two dye cartridges, and a purge fitting. The EZ-Ject is said to be easy to use because it requires only one connection to add dye into high-pressure systems.
Also new was an Optimax Jr.â„¢, a cordless leak-detection flashlight that reveals refrigerant leaks in cramped areas inaccessible to larger lamps, the company said.
