HI 8711 memungkinkan pemilihan dua set point dengan dua output independen untuk dosis asam dan alkali.
Setiap model menerima input langsung dari elektroda pH atau ORP atau dari pemancar melalui input 4-20 mA. Instrumen ini juga menyediakan output daya ± 5V dan terminal input untuk elektroda yang diperkuat. Selain itu, Anda dapat memilih konfigurasi output untuk menghubungkan perekam atau PLC, antara 0-20 atau 4-20 mA.
HI 8711 menggabungkan perlindungan dosis lembur yang bisa disesuaikan dari 5 hingga 60 menit. Jika dosis melebihi waktu yang dipilih, alarm akan dipicu dan kontak dosis akan dinonaktifkan. Fitur ini dapat diaktifkan atau dinonaktifkan.
