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.

The LAQUAtwin pocket meter is a simple and compact design that allows accurate direct measurement from a single drop of sample on its unique flat sensor (see image).
LAQUAtwin pen pocket meters are available for seven electrochemistry parameters, including pH, conductivity, various ions (Na+, K+, NO3, Ca2+) and salt concentration. This blog will be focused on pH meter calibration. How...
In the food industry, pH monitoring may be required during the production or pre-production process for a number of reasons including for microbe monitoring and taste purposes. In baking and bread-making there are a number of reasons why you would wish to know the pH - having a low pH in sourdough inhibits growth of pathogenic bacteria and in bread dough pH control agents (preservatives) may be...

Many pH meters also have a separate reading range which gives results in mV. This can be used for a range of applications.
1.) Checking your pH electrode calibration. Most meters automate the calibration of pH which makes it simple to perform and ensures consistency in results. However, when issues ar...
If not prepared properly there is a potential risk that sushi rice will develop bacteria, parasites, and viruses harmful to human health. One of the aspects that must be measured and controlled in preparation of sushi is the rice pH. If the rice has a pH less than 4.5 this will prevent bacteria growth and toxin production. This pH is lowered by the addition of vinegar and salt. ...
Testing pH in milk and dairy products is key to detecting impurities and signs of infection both upon collection of milk at the point of delivery. In the sterilization process, checking the pH is important as the lower the pH the faster the process will be. However, lower pH values in milk may also indicate that the cattle producing it may carry an infection.

pH meters are wonderful devices until they go wrong. You are then left with your sample sitting on the bench and in some instances, not knowing what is wrong. The following questions and answers are designed to help you diagnose the problem.
My pH meter won't give a fixed reading – is drifting or providing erratic...
One of the golden rules to pH measurement is to routinely calibrate your pH meter before measuring any samples. pH buffers have a known pH value, most commonly 4, 7 and 10. Calibration with these buffers gives the meter reference points to use whilst measuring the pH of other samples. https://www.youtube.com/watch?v=0t240gykR_I The TRUEscience SMART cap system uses a bluetooth signal t...
To measure the pH of soft cheeses is quite simple but the right equipment is required to ensure reliability and consistency of results.
A comparison can be drawn between the TRUEscience food testing kit and conventional pH meters:
TRUEscience smart pH meter kit for food testing has a spear shaped pH probe that allows the tip to pierce the dairy product or foodstuff so it is in good contac...
Q: I am looking to buy a pH electrode, many of them say "Na error over..." - what does this mean?
A: Sodium error is also known as alkaline error, and is a phenomenon that occurs at very high pH levels - usually pH 12 or over.
At very basic or alkaline pH levels, where Hydrogen ion concentration is relatively low compared to the Sodium ion concentration in the sample, you can see a Sodium...
Quality control (QC) checks are used to review the quality of production, processes and competence. It is essential to continuously test and challenge these aspects to ensure and maintain the highest quality process as possible. [caption id="attachment_11361" align="aligncenter" width="794"] TRUEscience pH Meter[/caption] For pH measurement, performing a QC check allows you to have an additio...
If you're looking at new lab equipment or instruments, you will probably shop around and research the options before you buy. But how can you get a more in depth feel for the products before you buy?
Jumping straight to a live demo of the equipment is not always the best way - this can delay the process if you need to wait for an appointment, so there could be faster ways of getting the info...
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...
