Designed for water quality experts, the Hach HQ411D Laboratory pH Meter is an advanced laboratory digital meter that takes the guesswork out of measurements. HQD laboratory meters connect with smart IntelliCAL<sup>Ⓡ</sup> electrodes that automatically recognize the testing parameter, calibration history, and method settings to minimize errors and setup time. The advanced HQD digital meter is designed to withstand years of continuous lab use. HQD bench meters feature a simple user interface that does not require manuals or training to operate. The HQ411D pH-meter is ideal for measuring pH, or mV/RedOx/ORP, in wastewater, drinking water or general water quality, soil, and food or beverages applications. A wide range of IntelliCAL electrodes and sensors are available to perform accurate pH measurements in any sample media types.
- High quality laboratory pH meter digitally deliver reliable measuring results with the aid of intelligent electrodes
- HQD laboratory bench instruments are easy to use thanks to the intuitively understandable user interface enabling one-touch measurements
- Large, illuminated graphic displays is easy to read, even in difficult light conditions.
- All the necessary information about each reading is automatically saved.
