Fluke TIS40 9HZ Thermal Infrared Camera with IR-Fusion, Picture-in-Picture, Voice Annotations, 3.5" LCD, Fixed Focus, 160x120 Resolution

works great. I recommend this product.

The battery lasts about 15 minutes. The unit takes 10 seconds to power on and off. The menu buttons are unresponsive a lot of the time. Definitely not worth the money we paid for it. The resolution was not as described. Poor quality instrument.

It has a frame rate of 30 Hz, but the temporal resolution is actually much worse than 1/30 s.

I received my TiS40 as promised but it appears to have a spot in the image while in the IR mode just below and to the right of the center of the image. The spot does not appear in the normal camera mode. Could this unit have a defect in the IR camera? The IR camera appears clean.

This thermal imager is middle of the road in the performance series. The construction is solid and reminds me of DeWalt tools with good feel and high quality plastics. The resolution of 160x120 is relatively small but other models in the line have larger resolution at greater expense if you need it. This model also has 30Hz refresh as opposed to 9Hz. A full gamut of modes are available. My favorite is IR-fusion which blends visible and IR images in 5 presets.What I do not like about this unit:SETUP: you can easily take the imager out of the box and start using it. However, if you want to use some of the other features such as wifi connection or Fluke Connect, you have to first download the SmartView desktop software and then go through multiple registrations to the fluke site. The software just has a feel of being old... like from 20 years ago. I did not like having to complete 3 different registrations to unlock functionality. The setup process as depicted in the Quick Reference guide is not intuitive. I would recommend going to Fluke and downloading the user manual as your first item to do.STARTUP: From power up to use takes at least 20 seconds. To me, that is a really slow startup time for a device. That's much slower than booting up Windows 10 or Mac OS!CHARGING: this unit really needs an external battery charger. Instead, you get a charging cable that you insert into the unit's head. I find this cumbersome and not only that, the screen is on the whole time showing charging progress. For the cost of this device, I would think the 2-bay battery charge base would have been standard.CONNECTIVITY: there has got to be an easier way! Connecting to the SmartView desktop software with the USB cable is about all I've managed so far. Using the Fluke Connect Mobile app is not intuitive. I've used digital cameras that connect to mobile apps that were much easier to connect than this thermal imager.In summary, this thermal imager performs well and appears well built. I feel the connectivity process is not where it needs to be and needs to be improved in future iterations of the product line.

This is a very interesting instrument, and quite useful for anyone who does maintenance of equipment or buildings. It can see temperature differences of less than one degree centigrade. As a result it can see bearings that are getting warm, electrical issues, and such things as heat loss from a building.In the latter case, I was impressed that it can easily see studs inside a wall. Now, I was using it when it was colder outside than inside. Studs conduct heat differently than insulation, so the walls, both inside and outside, are a different temperature over the studs. The siding on my home is the type that goes on in 4x8 sheets, and has vertical grooves. These are also obvious. Using this I can easily see where I need to do some work to stop heat transfer.If you point it at electrical outlets, it will instantly show you if an outlet is getting warm or hot. I found one outlet with nothing plugged into it which was quite warm, and it did have a bad connection.The battery, although removable, can be charged by connecting the supplied charger to the device. It comes with adapters to fit most of the different outlets found around the world. The device also needs a mini SD card if you want to capture images. That is not supplied.This works right out of the box, but you have to spend some time online to get all features activated, and you must also download the manual, since none is supplied. They do suggest you charge the battery before you use it. It comes in a soft, zippered case and also a hard case which holds the soft case. It takes 20 seconds or so to initialize when you turn it on. It is comfortable to hold, and not too heavy, but also does not feel flimsy. It is well balanced. There is a built-in lens cover, and the screen is clear. There is an adjustable strap which goes around your hand when you are holding it for added security, although the specs do say it can withstand a 6’ drop. I will let someone else test that.Our company is planning to offer an energy study where we show people exactly where their home or other building is losing or gaining heat, and we already have several clients signed up for this service. While too pricey for the average person to want to own one, it certainly has a lot of uses around the typical building.
