Seri UT139 adalah multimeter digital CAT III 600V yang dirancang untuk teknisi listrik. Fitur NCV-nya dapat secara efektif memeriksa status kelistrikan melalui pengukuran intensitas medan elektromagnetik. Model UT139E/S yang baru mencakup fitur-fitur khusus seperti LoZ (ACV) untuk mengukur tegangan ‘ghost’. Batang analog 31-segmen bawaannya juga memberikan teknisi listrik representasi visual yang lebih baik dari hasil pengukuran. UT139S dibuat dengan layar EBTN hitam dan merupakan meteran yang sempurna untuk bekerja di lingkungan yang gelap.
