Pros: Having a Remote Display is great in situations where it's hard to read the display or you want to check something while working out of sight on another place . Normally many of this situation would require two people, instead you can just go with this Fluke 233.
Cons: Some people have reported that the batteries will wear out faster than expected, which is the only flaw one can find on this meter. However it seems that newer models no longer have this issue.

1. The Fluke 233

This multimeter is great for one reason: It allows you to be in two places at once! This is a real innovation and I haven’t seen any other DMMs with this feature. As other models from Fluke it has a great build quality and safety. It includes a standard 3 year warranty which falls short to the lifetime warranty you will get when buying some other Fluke meters but is on par with DMMs from other manufacturers.

This meter is suited for most of the standard appliances in automotive, electronics, HVAC (heating, ventilation, and air conditioning), industrial, lighting and machinery. It’s made in the US, as oppsed to other meters which are mostly manufactured in China. If you have any need for the remote display feature, this is a great meter unlike any other on the market. Being able to read the display apart from the measurement can also often mean a substantial safety improvement and I can think of numerious situations where it is useful to have the display with you while measuring somewhere else. One example would be if you make measurements on a car and want to compare the result from the meter with the car controls (which are inside).

3. Features

The remote display really makes this one special. Other than that, the Fluke 233 has all the feature you will need for most applications. The DC Accuracy is sufficient for most applications with an VDC accuracy of 0.25% + 2. Average cheap meters have usually as much as 3%-5% discrepancy. For measuring AC it’s important that it is an True RMS meter, multimeters without this feature will often have more than 10% inaccuracy for nonlinear power sources, in fact this is very important as alternating current signals are everywhere.

It includes a thermometer aswell which is a nice feature to have. If you need it more often you will be pleased not to need an additional thermometer. It’s about the same size as the Fluke 87V and in typical Fluke quality it is very robust and durable. The accuracy of multimeters will normally decrease over time (and sometimes very fast if you use low-quality meters). From my experience with many meters I can assure that with on exception. DMMs from Fluke keep their accuracy for very long time, even decades without calibration. But anyway I would still recommend to check calibration from time to time, especially if you use it daily. With Fluke a recalibration after every couple of years will be sufficient, I’ve seen many Fluke meters holding calibration like the first day for more than 10 years. Another point is the battery life. 400 hours is a lot and can last for years depending on how you use it.

4. Comparable Multimeters

If you look for a remote display DMM you don’t have alternatives to this meter. It seems to be the only one on the market so far. If you could live without this feature you could aswell go with the Fluke 87V which as a bit higher accuracy. As an amateur you could go with a model of the Fluke 110 series. If you need features like a graphical display and data logging I can recommend the Fluke 289.

5. Other Reviews

On Amazon there are 13 reviews with an average of 4.1 of 5 Stars. On the homepage of the maufacturer 26 reviews are available with an average of 3.8 out of 5 Stars. Most of the bad reviews critize bad battery life, which is now fixed as of June 2013. New units seem to have no battery draining issues and keep the promise of 400 hours battery life.
