Well worth the money
Got the cl 110 and liked it that much I upgraded to the 800. Brilliant! The only niggke is it didn't come with the longer leads the cl 110 did but my long fluke leads fit in really well.

Good but corners have been cut...
When this first arrived I put the supplied batteries in and was met with a dead device & blank screen. After testing the batteries and reinserting them it came to life and has been fine since. Everything worked well but attention should be paid to the manual to fully understand all the settings options. Thereafter it's simple to operate, and comfortable to hold and use. The supplied thermocouple is only rated to180°C although the meter supports higher temperatures. I have a calibrated Testo class 1 thermometer & probes and found the Klein was consistently reading 1 to 1.5°C above that of my calibrated thermometer. This was the case using the same probes on both devices. I won't be using it to measure temperatures except when it's all I have to hand. The meter defaults to the farenheit scale but you can change that to default to celsius. The display backlight is bright and clear but the led work light is a bit dim. You might find yourself using the backlight often as some of the icons on it are tiny. It's a pity the leads are probes only as the inclusion of hooked and crocodile clip attachments would have been welcome additions, as would the magnetic hanger have been too. Where Klein additionally cut corners is with the case. It's a floppy'ish zipped case with no partitioning or mesh separators. It would have been nice to see separate compartments for the meter, leads, & thermocouples. It also needed some rigidity as it was flimsy and not well padded. I suppose most engineers will just wrap the leads around the meter and keep it in their work bag instead of the supplied case. The supplied user manual is quite small and could do with being better printed. Do yourself a favour and download the online PDF version instead. It's much easier to read. Despite the obvious corner cutting this is an excellent value Cat4 TRMS Clamp meter capable of both AC and DC ampere readings providing you focus on its core strengths and ignore the minor issues. As such I give it the thumbs up 👍.

Dropped just once from 20 cm and stopped working....
Dropped just once from 20 cm and it stopped working. Worked perfectly until it was dropped. I fixed it but taking it apart and tightening the screw holding the dial selector. Not sure how long the repair will last. Don't but this product.

Excellent meter with many useful features. I will mostly be using for AC/DC Volts and Current readings but so many other great features. Would be nice if the included pouch had an inside pouch for the cables and accessories. Used this morning on some DC current and voltage readings and works very well, is compact enough to get into tighter spots and the backlight and work light is a nice feature. Would highly recommend to anyone wanting a rugged, all-purpose tool for electrical applications. Tried the temperature feature which also seems to work well but an infrared temp probe with laser would be much easier. I will continue to use my temp gun for taking temp readings.

Excelente producto calidad precio para todos aquellos que hacen mantenimiento. Un producto con materiales de buena calidad, se siente muy bien en la mano, el peso es adecuado a su tamaño. Buena lectura en su pantalla, se agradece mucho la buena iluminación en la pantalla y la linterna integrada, muy útil cuando estas trabajando en lugares poco iluminados o cero luz. En su estuche cabe perfectamente el equipo y sus accesorios y un par de pilas extra. 100% recomendable. La entrega fue acuerdo a lo programado. llego en su empaque original y en perfectas condiciones.

“I recently purchased the Klein multimeter, and it has quickly become one of my favorite tools. The build quality is solid, and it feels durable enough for both professional and DIY use. The readings are precise and reliable, whether you’re measuring voltage, current, or resistance. The display is clear and easy to read, even in low-light environments, thanks to the backlight. It also has an auto-ranging feature, which makes it convenient for switching between different measurement tasks without needing to adjust settings manually. Another standout feature is its safety – it feels well-insulated, and the leads are sturdy. The battery life is impressive, and I appreciate the built-in stand that allows hands-free use. For the price, it offers excellent value and performance. I’d highly recommend the Klein multimeter to electricians, technicians, or anyone needing a dependable, accurate tool for electrical work.”
