(What's this)
This meter does just about everything except take out the dog. The unit ships with ample accessories (see picture A). The features I am most impressed with are the ability to easily measure inrush current (see picture B); two temperature ports (see picture C) and differential temperature (see picture D). Using the test leads it can also be used as a digital multimeter (see picture E). Picture F shows all the capabilities this meter has to offer. Little things that make this unit great are the large primary display digits with optional backlight; power down after 10 minutes of inactivity (optional) and drop tested to 6.6 feet.

(What's this)
If you are planning to buy a clamp meter this is the one to get. I have a few of them but this has many features built into one unit and it is sold at an excellent price point. It has a simple eight position dial used in conjunction with a select switch to change modes within the function. It also auto ranges but you can override into manual mode with a button. It accepts two K-Type probes for dual temperature readings. It has standard probes for measurement and also has a clamp function for measurement of amperage. Additionally there is a non-contact voltage sensor in the tip of the unit. The display also features a bar graph that is an analog representation of the measurement which displays three to five times faster than the main display. Measuring options: AC / DC Voltage (up to 1000V) AC current [clamp] (up to 600 Amps) AC inrush current [clamp] Microamps DC current (up to 200 micro Amps) AC / DC low impedence (LoZ) Voltage AC + DC Voltage AC Voltage + AC Amperage Continuity (including audible mode) / Resistance (up to 60 Mega Ohms) Capacitance (up to 6000 micro farads) Diode test Frequency / Duty Cycle (up to 1000 kHz) Temperature (-40F to 1832F) Differential Temperature I performed Voltage, Amperage, Frequency, Diode, Resistor, Continuity and temperature tests (see pictures). It performed accurately for each of the test. The package includes a soft case, the meter, standard probes, two K-Type probes, batteries and a manual.

(What's this)
This versatile multi-meter adds non contact in circuit clamp measurements as well as temperature probes. While designed for HVAC work it can be used for all manner of electrical and electronic measurements. It comes with temperature probes so I will not have to rely on my fingers for checking for overheating. It measures currents down to micro amps and voltages to millivolts so I will use it while designing circuits. Although sensitive, this measuring tool is rugged, they claim it can survive a six foot fall, but I will not deliberately put this to a test. Surprisingly this meter did not come with a line splitter which is needed whenever you want to measure the current of an appliance coming though a cable or power cord. I made one with a plug and socket from my scrap box, but I could also have sacrificed a short extension cord by separating the three lines. Since I do all kinds of electrical and electronic projects as well as household repairs this is one meter that should meet all my needs.

(What's this)
I have the skills to service my air conditioning system and recently obtained the new Klein Tools HVAC Clamp Meter (CL450) to supplement my equipment. This multimeter has everything needed for an HVAC Technician, and is very intuitive and easy to use. It comes with test leads, nylon case, batteries and two K-Type thermocouples for measuring differential temperature across a heat exchanger or cooling coil. After using the Klein Tools CL450 for several weeks, I am very impressed with the features and performance. This is a true RMS Cat IV 600 Volt meter with Clamp for measuring AC current and inrush current. However, it also has the ability of measuring DC Microamps for sensitive electronics, and resistance, continuity, frequency, duty-cycle capacitance and diodes. It includes a backlit LCD display for use in low lighting, and heavy duty plastic case, designed to withstand a drop from 2 meters. I highly recommend this tool for the professional HVAC Technician and Do-It-Yourself Handyman.

Gosh!!! Where do I start. This HVAC Clamp Meter has all the bells and whistles you would ever need to do just about any job that goes with that profession. I am overwhelmed at all of the things this tool can do and it comes from a company that has a long line of success in the professional electrical tool line. This tool is easy to use and if you have a problem, the directions manual can answer most of them. If you need additional guidance you can go to Klein tool customer service by phone or computer and they are more than willing to help out. This tool has so many functions, I can tell you of 18 for sure and I am sure that there are more than that in the right hands. I am a novice so I just stick to the directions in the manual. It is awesome to use. Its easy to understand and if you follow the manual its easy to use if you dont let it overwhelm you. This is a very good tool to have in the bag but not something everyone should have unless you know what you are doing.

Why does Klein Tools need nine different models of clamp meter? NINE! For the most part they all share the same suite of features with slight variations. Their newest models the CL900, CL450 & CL380 are all at the high end of the line but it's impossible to say which is the flagship model because when compared to the other two each has a couple features the others do not. Why can't they make one model that has it all? They really only need three models at three different feature/price points but instead we are subjected to these marketing shenanigans that require one to purchase several of their meters to have it all.

Seems to be a good meter for the price but really haven’t used it much. Purchased mainly for the rush current measurement feature.
