Kami jual Kyoritsu KEW 4106 murah dan asli. Silahkaan hubungi kami di 0822 2409 5859 atau WA 0822 8816 0875. Kyoritsu KEW 4106 adalah Earth Resistance dan Resistivity Tester yang memiliki:
- Uji arus tinggi hingga 80mA menghasilkan resolusi 0,001 pada rentang 2Ω.
- Metode Penyaringan Tingkat Lanjut (berdasarkan FFT Fast Fourier Transform) mengurangi gangguan kebisingan untuk mendapatkan pengukuran yang stabil.
- Pemilihan Otomatis dan Manual pada Uji Frekuensi Saat Ini pada empat pita (94/105/111 / 128Hz). Dalam mode Otomatis, KEW 4106 akan memilih Frekuensi yang paling sesuai.
- Beberapa sub-hasil dapat ditunjukkan pada layar: Resistance of Auxiliary Earth Spikes, Frequency of Test Current, Voltage dan Frequency of Interference (noise), Residual Resistance Rk, dll.
- Peringatan untuk kebisingan yang berlebihan dan ketahanan Basis Auxiliary Earth yang tinggi.
- Tampilan Grafis Besar dengan lampu latar untuk pembacaan di daerah yang tidak menyala dengan benar.
- Hingga 800 hasil pengukuran dapat disimpan dalam memori dan diingat pada layar.
- Hasil yang tersimpan dapat ditransfer ke PC menggunakan perangkat lunak "KEW Report" dan adaptor USB (Model 8212-USB) yang disertakan.
- Desain yang kokoh dengan perlindungan IP54.
