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...
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...
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...
The portable meter SD 310 Oxi from Lovibond / Tintometer meets the day to day demands for sturdy and reliable measurement of dissolved oxygen, with an instant sensor.
The well known Clark-oxygen-sensor with integrated temperature compensation allows instant measurement without the need for time-consuming polarisation.
A direct, convenient user interface facilitates meter operation...
Hanna Instrument's latest multiparameter meter the HI-98194 offers a comprehensive solution for measurement in the field.
The IP67 rated waterproof portable meter measures up to 12 different water quality parameters - the multi-sensor probe directly measures pH, ORP, conductivity, dissolved oxygen, temperature and pressure.
Additional parameters such as pH-mV, total dissolved solids, resi...

Mettler toledo have just announced new firmware for the Mettler Seven Excellence series of electrochemistry meters. The v2.2 is the newest firmware release for the Mettler high-end benchtop multi-parameter instruments. The new firmware features a number of important improvements to SevenExce...
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...
IP ratings on instruments what do they mean?

Thanks for sharing such a great information.. It really helpful to me.. I always search to read the quality content and finally i found this in you post. keep it up!
I came across your article about "DPD Tablets" on Camlab Info, and it's a valuable resource for anyone seeking information about water testing and analysis using DPD tablets. Your explanation of their usage and significance in water quality monitoring is quite informative.
This article on nanocolor tube tests is a gem for analytical enthusiasts. The idea of zero calibration is intriguing, and your detailed explanation makes it accessible. The step-by-step process helps demystify the technique for beginners like me. The use cases you've highlighted, particularly in...
Grant have introduced the new Controlled Rate Freeze Thaw (CRFT), which is a liquid nitrogen and cryogen free controlled rate freeze and thaw system for cryopreservation in a wide range of applications. Cryopreservation is a process where biological materials such as cells, tissues...
A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be...
Purchasing items using donated funds without the burden of VAT will now save many Millions of pounds each year which can be put to better use in advancing scientific knowledge to provide new treatments and cures that will shape the medicines of the future.
Working with pressure/vacuum conditions in the lab is common but not all products are designed to withstand this. Products with appropriate geometry and wall thickness are suitable for working safely with pressure. For example, filtering flasks, desiccators, or flat flange vessels, as well as...
