ETCR3620 Portable Milliohmmeter
ETCR3620 Portable Milliohmmeter DC Low Value Resistance Tester
ETCR3620 Portable Milliohmmeter, juga dikenal sebagai Dc Low Resistance Tester, DC Resistance Tester, Ohm Meter, yang digunakan untuk mengukur resistansi kawat pada kabel, resistansi kontak sakelar, konektor dan relai, resistansi DC rendah pada kumparan belitan, motor dan resistansi saluran transformator, resistansi sambungan antara bagian paku keling logam dan komponen logam, dan resistansi sambungan antara konduktor yang terhubung pada tiang jaringan tanah. Ini banyak digunakan di perusahaan industri dan pertambangan, stasiun pemeriksaan kualitas konstruksi, pengawasan perusahaan, unit konstruksi,, perusahaan proteksi petir, departemen tenaga listrik dan pabrik mesin kapal, dll.
Miliohmmeter Portabel ETCR3620 terdiri dari host dan kabel uji. Instrumen ini mengadopsi teknologi mikroprosesor dan metode 4-kawat presisi untuk menguji, akurasi tinggi, dengan teknologi pengukuran metode jembatan listrik lengan ganda, bukan meminta untuk menguji resistansi saluran. Alat uji resistansi: 200mΩ, 2Ω, 20Ω, 200Ω, 2kΩ, 20kΩ, arus uji maks: 1,2A. dilengkapi dengan baterai lithium berkapasitas besar, fungsi penyimpanan, mudah dioperasikan dan dibawa.
