Work’s fine- recommend!

I am well impressed with these little units. The digits are very easy to read and it appears accurate. In particular it surpasses all the other plug in units which are often difficult to read especially in inaccessivle places and which are practically useless in the absence of a battery as their readings are los as soon as unplugged or if the power fails. These units retain cumulative energy usage and can also be reset manually when required.I bought two to make up my own energy monitors and needed a housing for them. Initially I bought two ASHATA 3 module consumer unit boxes. They are rubbish, flimsy, difficult to open and far larger than advertised so they are going back. In their place I bought two Wylex ESE2 enclosueres which are good looking and very sturdy boxes which will make perfect housings. Bet bit - they are only £3.55 each - incredible!! A bit of work fitting plugs/wantering sockets and I shall have two first rate energy monitors.

Had a electrician to fit mine along with a change over switch, seems to be OK at the mo,

Bright, easily read display, though the current reading seems inaccurate when you work it out from watts/voltage (I believe this was mentioned in an earlier review).

I bought this to get more specific data about my heat pump energy usage, as the built in Mitsubishi data is too high level. I particularly like the fact that this device does not interfere with the wiring, as the sensing is done by running a power wire through a hole in the device, unlike some others where you connect L & N in, and L & N out. If the device were to fail, it will not effect my heat pump.

I used the meter to measure the electrical output from a petrol generator that I can run my house with during a power cut. The meter allows me to decide which items I can switch on and which to switch off. The meter works really well and I am very pleased with. The only mistake I made was to buy a two position enclosure because there wasn't enough space for the additional wiring.

Very accurate

excellent little din rail mounting meter .I used it for measuring solar output from a 50hZ sine wave invertor
