Designed for your water quality applications measuring simultaneously pH and Dissolved Oxygen (DO), the Hach HQ40D portable multi meter is a two channels advanced handheld digital meter that takes the guesswork out of measurements. The Hach HQD digital multimeter combines reliability, flexibility and ease of use. The HQD portable meters connect with a wide range of Intellical smart electrodes addressing different parameters, sample types and operating environment for water quality, environmental and treatment process purposes. The Intellical probe automatically recognize the testing parameter, store the calibration history, and method settings to minimize errors and setup time.
Intellical™ PHC101 and LDO101 are digital combination pH and Dissolved Oxygen electrodes with built-in temperature sensor. PHC101 has low maintenance needs thanks to a non-refillable gel-filled single open reference junction. The LDO101 is fitted with an automatic pressure sensor module and a temperature sensor. The DO sensing cap comes with an iButton to track days in use and remind remaining life of the sensing cap element. These electrodes are shockproof with their plastic body protecting down to the sensing element. Ideal for measuring pH and Dissolved Oxygen in wastewater, drinking water and general aqueous applications. The PHC101 is not suitable for use with organic solvents or samples with pH less than 2.
