I have a lot of DIY electrical projects. Most are in my Jeep as it's the platform for many toys, but I have them all over. Part of this is a LiFePO4 bank that I initially built for car audio but quickly discovered could be used for a lot of things. I wanted to keep tabs on the temperature because lithiums don't like to be charged below freezing. I wanted to see the temp so that I could operate a set of heating pads to regulate the cell temperature. When I saw these I decided to try them.They work! These are AC, which I have working off household power, so just keep that in mind when buying. They show the temperature clearly and lets me see the temp at the bottom, middle, and top of my bank.Overall I'm happy with these sensors. The display is bright and clear and they seem to be accurate.

Operating off two wire AC voltage input from 50 - 360 Volts these are useful when mounted into a display panel. Consider these as a steel cabinet mount type thermometer for measuring internal equipment temperatures and for that purpose are perfect.

I haven't used these yet because the wiring isn't labeled at all. It has a 3 wire pigtail coming off the back and I havent taken the time to see what's what just yet. I like putting indicators on my projects to know if the power is there or not and assist with troubleshooting.I wish they tossed a little instructions sheet in with these but ill get it figured out.

Connect this meter across any single phase AC line to monitor the frequency. Display comes on at around 10Volts and displays the frequency in Hertz. At 50VAC the meter is quite bright and draws about 6mA. At 100VAC the display is only slightly brighter and draws about13mA. My Variable supply topped out at 151VAC and the current draw at this voltage was 26mA. The frequency is very accurate. Below 9.0VAC Frequency measurement becomes erratic or may even pause. As expected, as the line frequency increases, the sensitivity of frequency measurement increases.

I've used lamps from this company before (multiple times). Excellent products. They look great when mounted, are bright, easy to solder leads onto.In this case I thought the lamps were 50-300vac, but I actually got 220vac + so I can't use it for my intended application. That said I'm holding onto them because I might be able to use these to count on/off cycles for a 220v fan which this would be great for.

Counts pulses coming in on the middle wire. Counts up to 999999, but it wraps the digits into two rows which is not immediately apparent.

I order these as a replace for a power light on my diesel generator. I needed a light that worked from voltages 110-240. When I saw this I though that it would be even better than a simple light. It does light up bright, but will also tell me the frequency the generator is running at. They come in a 3 pack, I may put on in my breaker box so I can monitor the frequency from inside the house when my generator is running.

I just had to apply power and position the sensor and I had the temperature in Celsius.The wire for the sensor is 37" long, which is enough to reach all of the locations I needed these for.The reaction time for temperature changes was quick and comparable to my infrared temperature measuring tools.The digits are clear, bright, and easy to read.I recommend these Digital Thermometer Displays for monitoring.
