The Hanna Instruments BL7916-1 is a combined pH controller and chemical dosing pump intended for use in water treatment applications. It has a flow rate of 7.8 to 13.3 liters per hour (LPH). The pH controller is accurate to 0.01 pH of set point for control of acid or base chemical dosing. It has a control panel with LCD, set point trimmer, selection switches, and auxiliary contacts for connection to external devices (sold separately) such as fluid-level control. A transparent plastic cover protects the control panel from contamination and liquids. The power supply accepts 115V, 50/60Hz input power. The pH controller/pump unit includes suction and discharge valve assemblies, 7' of LDPE tubing, a power cord, and instructions. Required accessories are foot valve assembly and injection valve assembly (all sold separately).
