Lovibond has two variations in its range of portable waterproof handheld meters. These electrochemical measuring instruments are designed for safety, mobility, and ease of data retention and storage.
The data loggers regularly save the collected measurement data which can be transferred to the computer via USB interface (serial or analogue).
With the SD 305/315/325 series, the instrument is ...
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 SD 400 Oxi L is Oxygen meter which allows the measurement of dissolved oxygen (DO) at a high level. This is done thanks to the optical technology of luminescence. It uses an Optical DO probe which has distinct advantages: Low maintenance Easy calibration Fast response High accuracy The applications for this meter include: Waste Water Water Treatment Marine Water Surf...
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...
The portable FiveGo range by Mettler Toledo have had a re-design. They are now available with IP67 waterproof protection whilst still maintaining ergonomic design and intuitive operation. There are three meters in the range to cover pH, Conductivity and Dissolved Oxygen measurements. The FiveGo Design The large, well-structured display is great for easy viewing The LCD display ...
The Edge meter by Hanna Instruments can be used with one probe to measure either pH, conductivity or dissolved oxygen. For maximum flexibility this smart slim unit allows use on the bench top, as a handheld or in a wall mount - whichever is easiest for you.

Ask the expert:Â What are the differences between Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD)?
Answer: Both COD and BOD test methods aim to give an indication of the amount of pollution in a water sample. COD is the amount of oxygen required to chemically breakdown the pollutants. Whereas BOD is the amount of oxygen required to do this biologically through micro-organisms. T...
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...

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...
