About This Product

■Measure ORP with titanium body electrodes

The HI 991001D and HI 991003D feature robust titanium body electrodes, making them perfect for outdoor use. It is popular for environmental surveys of wastewater, river water, etc., and septic tank management. With the HI 991003D, ORP can be measured at the same time as pH.

■This is the point

Adopts a titanium body electrode. It is more durable than those with a glass body, so it can be used outdoors and in tough environments. (The tip of the electrode is made of glass) The electrode has a built-in amplifier that prevents noise errors and enables quick and stable measurements. The pH electrode status is displayed on the left side of the screen for 12 hours after calibration. By understanding the condition of the pH electrode, which is normally invisible to the naked eye, you can appropriately determine when to perform maintenance or replace it. The calibrated standard solution value is also displayed on the screen. Connecting the electrode and main body is easy. The main body is IP67 waterproof, and the connections are also fully waterproof.

■Features

・Information of reading timing by displaying measurement stability mark ・Hold button to fix reading value ・With automatic temperature compensation - Approximately 1,400 hours of use with 3 AAA alkaline batteries ・When the battery level drops below 10%, you will be notified on the screen. ・Comes with a case that is convenient to carry

■Set contents

Main unit, pH electrode (depending on model), 1 dose each of pH4.01 & pH7.01 standard solution, 2 doses of electrode cleaning solution, 100mL plastic beaker, 3 AAA alkaline batteries, resin carrying case, Japanese instruction manual, etc.
