RCD/ ELCB Loop & Polarity Tester
Overview
The MT312 is a compact, versatile tester designed for 3-wire AC circuits, supporting ELCB/RCD testing, loop impedance measurement, and polarity verification. It features a Non-Contact Voltage (NCV) function for safe AC voltage detection and displays wiring status clearly on a large, easy-to-read LCD screen. Voltage measurements between Live and Neutral, as well as Neutral and Earth, are shown directly on the display. The MT312 automatically performs loop impedance testing to verify correct wiring, with intuitive LED indicators: Green for Good, Orange for Check Circuit, and Red for Urgent Check, highlighting any potential faults. During ELCB/RCD testing, the device measures fault trip times up to 99.9ms, with a 10-second buzzer alert confirming a successful trip. A key feature of the MT312 is its interchangeable leads, enabling testing of standard power outlets with the included test leads or distribution boards using the optional MT350L test lead set.

Perfect After-Sun Lotion
This lotion feels amazing after being out in the sun all day. It keeps my skin soft and hydrated without feeling greasy, and the scent is light and tropical. I also love the subtle glow it gives my skin. Great size for keeping in a beach bag or taking on vacation. Definitely recommend if you want your tan to last longer and your skin to feel moisturized.

Smells Devine
I got this Hawaiian Tropic After Sun Lotion to use after long beach days this past summer, and it quickly became part of my routine. It feels soothing on the skin after sun exposure and absorbs nicely without leaving a greasy layer.
What I noticed most is how well it helps maintain my tan. My color seemed to last longer and fade more evenly when I consistently used it. I even saw a difference when I was using tanning beds — my skin looked more hydrated, which made the tan appear richer and less patchy.
The scent is another highlight. It has that classic tropical fragrance that instantly smells like summer vacation — warm, beachy, and nostalgic without being overpowering.
I’ll definitely be repurchasing before my upcoming vacation because it makes such a noticeable difference in how my skin looks and feels after sun exposure.

Better than expected!
I was pleasantly suprised by this lotion. I bought it to help maintain my self tanning lotion, and also for days after being in the sun. The lotion is not too thick and not sticky. The scent is tropical and nice, bit it’s not too strong. I will buy this lotion again.
