Neiko Professional Digital Laser Photo Non-Contact Tachometer - Accurate to 99,999 RPM Measurement Review

Neiko Professional Digital Laser Photo Non-Contact Tachometer - Accurate to 99,999 RPM Measurement
Average Reviews:

(More customer reviews)
I bought this to determine how far off my motorcycle's tach was.It has remarkable pickup of nearly any bright, reflective surface such a chrome or semi-bright aluminum cast so be careful to provide decent background surface isolation.Don't work about running out of reflective tape.I was able to get great results using Testor's silver model paint painted directly on to my engine's flywheel.You can accomplish the same results by painting a spot on a piece of masking tape and sticking the tape to whatever you are reading from.

The down-side of the device is that it is pretty much contoured for hand-held use.I had to rig some velcro to it so that I could strap it to a tripod (leaving me with less to juggle why adjusting carberators).The strapping does make it a little difficult to manipulate the buttons while still being able to see the readout.Don't get me wrong, using this as a hand-held works quite well but does require a steady hand if you are shooting through a narrow space.Overall, I'm quite satisfied with it for the little $$$ it cost.

Amprobe PM55A Red and Black Compact Precision Digital Multimeter Review

Amprobe PM55A Red and Black Compact Precision Digital Multimeter
Average Reviews:

(More customer reviews)
Pros:
+ Super small and light
+ Works fine
+ Continuity checker is reasonably loud
+ Much better quality than those small Radio Shack mini meters, albeit a tad larger
+ Case is nice

Cons:
- I don't like that the probes do not plug in with standard probe plugs.This means you can't use all your standard Fluke clamps, alligator clips, and standard probes.They could have fit it that way and still kept it flat, and included these mini probes.This ALMOST made me give it three stars, but then one has to take into consideration that its purpose is for travel, not perfection
- The instruction manual (yeah, I know... how hard can it be) doesn't fit into the case.Were it just a bit smaller, it would fit fine.That's just weird.
-Don't like that it uses a whacky small battery (CR-2032; easy to find at any watch store or radio shack, but hard to find in the middle of nowhere).Understand it has to to be so flat, but I'd rather a small bump and two AAs or AAAs.I am probably alone in this opinion.Still, how about inside having a built in holder for a spare battery; that way if you're stuck somewhere and it runs out, you have one in there.I put an extra one in the pack just in case.You should too.

Palm-Size Handheld Digital Multimeter, DT830B Review

Palm-Size Handheld Digital Multimeter, DT830B
Average Reviews:

This is not a Fluke nor is it even a Radio Shack, but the price is right and as an occasional household tool the DT830 works well enough. However If you are an electronic hobbyistthis meter will probably not meet your needs. The Ohm-meter function works poorly in it's lower ranges and the diode check has no feedback tone. I could go on about its crude finish, but it's still a bargain if you need something cheap and expendable.

Sinometer DT9205 8-Function 32-Range Digital Multimeter Review

Sinometer DT9205 8-Function 32-Range Digital Multimeter
Average Reviews:

(More customer reviews)
This multimeter has many good functions, but it is poorly made. Don't expect to put it in a drawer for 2 months and be able to use it: It drains the 9V battery quickly, even when not in use. In order to change the battery you have to remove boot and then the entire back (no separate battery compartment). I suggest spending a few bucks more and getting a better quality meter.
