The TIS 1005 is a pocket sized checker for indicating loop impedence, socket polarity and RCD 30mA are all ok. Indication is by LED's and buzzer. It is an ideal unit for initial "checking out" of a 13A socket and will advise if the circuit is ok, needs attention, or needs urgent attention.

replaced my 3 light ester with this - excellent - easy to use and seems to do exactly what it says. If your replacing a 3 light tester- buy one like these much more useful.
