How to Calibrate the Hach LDO Probes

Let us first look at the probe. The Hach dissolved oxygen probes are equipped with a measuring LED that emits a pulse of blue light and a photodiode as a light detector. The probes are also equipped with a sensitive luminescent coated spot that is exposed to the sample. The measuring LED emits a pulse of blue light which irradiates the back of the oxygen-sensitive spot. The coating mate...

Measuring Dissolved Oxygen in Wine

Oxygen can dissolve into wine throughout production causing wine oxidation which in small amounts can be beneficial to some varieties such as red wines, but in large amounts can shorten the wine's life and lower the quality. Being able to measure the dissolved oxygen throughout wine production allows the winemaker to control and influence the amount of oxygen exposed to each variety before bott...

What type of electrode should I use to measure Dissolved Oxygen?

Quite simply, dissolved oxygen (DO) is free (non-compound) oxygen present in water. Oxygen dissolves by diffusion from the surrounding air, gained by aeration from turbid water or a waste product of photosynthesis. DO is vital to maintain aquatic life from fish to plants to bacteria and thus an important parameter to be able to measure. There are many factors to take into account when ch...

Can I use two probes of the same type with a Hach HQ40D meter?

Yes - two probes of the same type can be used with the Hach HQ40D. The Hach HQ40D is a multi meter with two channels - this means it can accept two probes and measure two parameters from pH, conductivity and dissolved oxygen simultaneously.   If you want to compare two samples you can attach two of the same type of probe, e.g. two pH probes. The split screen will then show...
