HQ40D Portable pH and Dissolved Oxygen Meter

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™ PHC301 and LDO101 are digital combination pH electrode and Dissolved Oxygen sensor with built-in temperature sensor. The PHC301 has a refillable with two ceramic pins reference junction. These electrodes are shockproof with their plastic body protecting down to the glass bulb sensing element. 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. The PHC301 pH sensor and CDC401 Conductivity Cell are recommended for wastewater, drinking water and general aquous applications. The PHC301 is not suitable for use with organic solvents.
