Factory QA benches checking incoming ingredients and finished product: moisture, pH, water activity, and microbial counts. Most orders here repeat against a fixed test method rather than changing month to month.
For measuring pH in various industries including food, beverage, textile and cosmetics, and for checking the acidity and alkalinity of raw water sources and wastewater treatment ponds.
The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference…

The HI83742-25 is a high quality reagent that is pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. This reagent allow for a direct reading of the sample.
The HI83740-20 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow a method in which the reaction between copper and reagents causes a purple tint in the sample.
