Will this detect electricity in swimming pool.

Asked by Mmarky May 10, 2018
2
Answers

The Klein Tools NCVT-4IR can detect the presence of AC voltage from 12-1000V when the sensing antenna is in close proximity of a current carrying conductor. Please see the product instructions for further details on product usage. We recommend contacting a qualified electrician for the resolution of electrical wiring concerns.

Does this read temperatures on aluminum metals

Asked by john December 6, 2017
2
Answers

It will read the surface temperature of any object you put in front of it. However, be aware of the beam spread being 1" for every 4" away from the object. If you are too far away from a small object you will be reading some of the background beyond the object which will be averaged into the reading.

I bought this tester for work back in December 2018. I really liked this tester for being able to do 2 things instead of the usual 1. I don't like to have to carry any more tools than I have to on my job. However, it is not as rugged as you would expect Klein tools to be. It fell out of my cargo pants pocket down by my knee and the top of the cap that holds the batteries in broke right off. Of course, the little metal piece that connects to the battery got lost. I would really like to give this tool a better rating, which I will happy to do, if I can get the cap replaced promptly.

(What's this)
A well-designed and constructed multi-use test instrument, this tester, although marketed to the HVAC sector, will also be useful for electricians and (with the frequent installation of electrically powered on-demand water heaters) plumbers. The rugged clip provided will secure the tool either in one's pocket or tool pouch and the moisture resistant, O-ring sealed battery compartment will add to its longevity under adverse weather conditions. Electrically, the tool will sense from 12V to 1000V. below 120 volts, the tool will emit a slow beep...above that level, the beep will be more rapid. Frequencies from 50 to 500 Hz can be sensed (which may be a limitation if one works with higher frequency variable Frequency Drive motors operating at higher frequencies). The 4:1 sensing "cone" ratio for the IR thermometer will be adequate for most applications, such as checking for proper flow in condenser or evaporator coils (for the HVAC tech) or overheated contacts and terminations for the electrician. The tool is rated for use down to 32 degrees F (no doubt limited by the LCD display) requiring some care as to storage and use, however the sensing device can measure down to minus 22 degree F (just keep it in your pocket in between readings). Operation is quite intuitive in either temperature or voltage sensing modes. If one prefers to read temperature in degrees C, the display can be easily toggled to do so. The voltage sensing element is well protected by a substantial plastic "nose" to prevent damage. All in all...a very well built tool.

(What's this)
A great combination of "no contact" meters in a small package. I've used no contact testers for both temperature and volt over the years but this is the first time I've run across both no contact volt and temperature tester and having it pocket size really makes this an awesome tester. Meant ideally for the HVAC tech., however the low cost of this combination meter makes it worth having for any Diy-er. The compact size fits in a shirt pocket without feeling too bulky. The tool itself seems to be well constructed to hold up to the rigors of being in a pocket or a tool bag. The sensor end for both temperature and volt is well built. I've experienced tip breaks on other no contact volt meters however Klein did a great job in the design and construction of the NCVT-4IR. The display is only for infrared temperature reading and battery status. The display is backlit for easy reading in low light areas, however, the display does not provide voltage measurement. The tip will change colors from blue (power on) to red (voltage detected). Two buttons on the NCVT-4IR allow operation between temperature measurement and voltage detection. There are also options to turn on/off the laser spot for temperature and change from Fahrenheit to Celsius as well as select on/off audible for voltage detection. Batteries access is easy and takes 2) standard AAA batteries. Both temperature measurement and voltage detection work very well. The distance of the tester to the surface temperature being measured will affect accuracy but this is true for any infrared thermometer. Pros: - 2 great no contact test meters in one small package - easy to operate and use - well constructed, durable - great features without being cluttered with buttons or operation menus - takes standard batteries Cons: - none, I've been using for about a month and I absolutely love this tester

Handy addition to the at home toolbox for any DIY'er. I do much of my own electrical work around the house, running new circuits, adding lighting and outlets, both low and high voltage. Normally I would get the multi-meter and touch both leads to the exposed wires to determine if they're live or not. This meter eliminates the guesswork. I know quickly and simply if the wire is live or safe to work with. The thermometer is a nice add-on, but not totally necessary for at home use. However for the price you can't beat the combo. Tester also is a good size and has a nice weight to it, doesn't feel flimsy in hand.

(What's this)
This was easy to use and well-designed! This Klein non-contact voltage tester with a built-in laser infrared thermometer has a lot of useful design features which will make it a go-to tool for testing voltage and temperature. I liked the design of the battery compartment in the body of the tester. Klein wen to the trouble of including a rubber O ring (see picture) to seal the battery compartment (it takes two AAA batteries). In my experience, Klein has always made a high quality tool, and this one certainly is high quality. The plastic case is very solid so this will take the usual wear and tear of being in a tool box or getting dropped frequently! It is very rugged. The laser function is good for testing temperature in hard to reach places, like inside an HVAC unit or heating/cooling pipes just out of reach but still within sight. The voltage testing part of this tool is an audio and visual display (not a digital readout), as explained in the 12 page fold-out instructions that come with the tester (see picture). I found it easy to use – just hold up the end of the tool to the circuit, and a fast red light blink (see picture) is high voltage (120V), and a slow red blink is low voltage (12V). The blue light indicates no voltage present (see picture). I highly recommend this tester because of its excellent design and high quality. It is a must-have tool!

This is a GREAT! addition to my electricians tool bag. It is small (6" long) and lightweight (3 oz). It comes with a sturdy pocket clip which allows you to carry it around in your front pocket. This small non-contact tester easily allows you to detect the presence of AC voltages in wires, sockets and switches. Bright LED lights and an audible alarm indicate if a wire is energized and whether it is less than 120v AC or greater than 120v AC. The detection range for AC is 12v to 1000v. The tester includes a non-contact infrared thermometer. Included is a built in red laser pointer for aiding in pointing the thermometer at the desired location. I measured the temperature of an ice cube and a pan of boiling water and found it measured pretty accurately. See the photo and video.

I am an experienced HVAC service technician who has received this product as part of a promotion #kleincrusaders. In the time I have been using the tool it is able to quickly and accurately determine low and high voltage within energized circuits with visual and 2 different audible sounds. The sensitivity is perfect as it allows you to determine which wires are live and which are not even if the wires are in close proximity to one another. The infrared thermometer is useful and appears to be fairly accurate at about a third of the size of most infrared thermometers. Highly recommended tool for any tradesman who works with electricity or varying temperatures.

I was hoping on voltage testing it had an digital read out.It doesn't that just for temp read out.Be nice to have that feature besides just beeping at me . Kinda like to know how much voltage I'm dealing with.Since nothing really explained it I guess low beep is low shock and fast beep is knock you out of boots who knows.
