Hach have just launched their new HQ meters - a range of robust portable electrochemistry meters ideal for use in the field and beyond. Models are available with up to three input channels and have advanced features that you would not normally find in a portable meter.
The HQ range by Hach are robust, portable electrochemistry meters.

Simple and easy calibration - most measur...
Conductivity (also called electrical conductivity or EC for short) is a measure of a substances ability to conduct an electrical current and this can be measured using a conductivity meter. In the farming and the agriculture industry, conductivity can be used as an indicator of overall soil nutrient levels.

What is conductivity? Conductivity is a measure of the ability of a substance to conduct an electrical flow through it. In water, many compounds and molecules (such as dissolved salts and inorganic materials) dissociate into constitutive ions. Ions are small sub-atomic particles and carry with them an electrical charge; either positive (cations) or negative (anions). These particles help condu...
The Bluetooth enabled Ultrapen meters by Myron L Company for pocket sized, portable testing of pH and conductivity are a great way to take, store and send readings. The app to take readings from the pens has now been updated to be compatible with iOS 9 devices - just search the app store for "Ultrapen PTBTx" to download the latest version and get testing.

Mettler Toledo have released their new FiveEasy range of benchtop meters for pH and conductivity. The new models, still part of the FiveEasy family, have been redesigned and have had extra features added. We were impressed at the compact, clever design and the flexibility the new range offers. [caption id="attachment_8141" align="aligncenter" width="300"] The new FiveEasy range, but what ...
Laboratories using a deioniser system to generate deionised (or DI) water in house should test the water produced regularly, to ensure the system is working well and producing water of the required purity. [caption id="attachment_8125" align="aligncenter" width="300"] How can you test your DI water is pure enough?[/caption] Conductivity is usually used as a good indicator of the quality, ...
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?

What is Reverse Osmosis and how do I test the water?
[caption id="attachment_3360" align="aligncenter" width="294"] osmosis[/caption]
OSMOSIS
Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached. Reverse Osmosis (RO) is a membrane process of purific...
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...
