KETOTEKVoltmeter Ammeter, 20A 80-260V Electric Circuit Tester, LCD Display Multimeter with Power Overload Alarm, Energy Reset, Backlight Control, Data Storage when Power Off

I was concerned to monitor my PC power usage as it is left on 24 hours in order to do backups etc.I used a C13 'kettle' plug extension cable, which I cut in half and then wired both end to the monitor so that I can put it in line with any device that uses a kettle plug power lead.The accumulated KWh seems to be accurate.

Good piece of kit

Installed quite easily - screen a bit difficult to read if you are at the wrong angle but seems to show the required readings okay. There is a back-light too.

Wired into 240v a.c. circuit. No reading for current or watts Very disappointing

Ordered on 10 December 2021, and I must admit it’s taken me a while to actually get round to fitting it, but I finally connected this in last night and it’s not working by the time I looked at it again this morning, so it’s barely lasted 12 hours. The backlit background no longer works and the lcd screen is only visible from an angle, it’s as if it’s running out of batteries. Very unprofessional. It would seem that it only has a 30 day warranty period and Amazon make it very difficult to get in touch with the supplier as they are not listed. It’s almost as though Amazon don’t want to know either. Save £20 and buy a different one.

When the product is operating it gets hot where the wire terminal is, and blacks out the screen.Tried wiring different ways to no avail.Measured voltage different multimeter reading, so not reluably accurate as far as i can tell.

Inaccurate on voltage reading, amp reading fixed at 0.02 amp rubbish

Had this item about 6 months now. Worked fine for about 4 and the last 2 months the unit reports utter jibberish. Connected to a 230v site and it’s reporting between 68 and 71 volts. Not impressed with the one I have purchased.

Efficace et précis dans les mesures.Fait son travail une fois installé.

Artículo necesario si quieres saber en tiempo real el consumo que estás teniendo es esos momentos, así como saber si no tienes a nadie "enganchado" a tu red. Aporta las medidas justas y necesarias para controlar la corriente que llega a tu casa, el consumo total que tienes durante el mes y una alarma muy práctica que te avisa cuando te pasas del consumo instantáneo que tienes contratado. En resumen, un aparato que te puede ayudar a ahorrar unos euros y tener un buen control de la corriente que te llega a casa. Muy recomendable.

prima controle apparaat voor spanning,stroom,vermogen

Prodotto facile da installare per un elettricista o simili. Molto intuitivo ed efficace. Consigliato puoi misurare i consumi reali di un utenza, di un elettrodomestico importante e altro. Ottimo

Lo mejor el diseño pequeño y compacto.Lo peor es que dudo un poco de su efectividad ya que en el voltaje de AC de mi piso me marcaba 247V. y con un multímetro me marca 232V.
