Hach HQ40D [8507100] Portable pH and ORP/mV Meter, Laboratory Kit w/ 1m Cable

Designed for your water quality laboratory applications measuring simultaneously pH and ORP, 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™ PHC281 and MTC101 are digital combination pH and oxidation reduction potential (ORP/Redox) electrodes with built-in temperature sensor. The PHC281 is a pH refillable probe made for difficult samples. These laboratory electrodes are shockproff plastic body protecting down to the sensing element. The PHC281 refillable pH electrode has a high electrolyte flow rate and a large open junction ideal for difficult samples, such as Low Ionic Strength (LIS), Ultrapure, dirty samples and samples with high solids content. The PHC281 and MTC101 are not suitable for use with organic solvents.
