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...
Palintest have announced that the ChloroSense, ChlordioXense, ChlordioX Plus, ChloroSense HR and PAASense units have been discontinued and have been replaced by the Kemio. The Kemio is a multi-parameter next generation instrument capable of measuring chlorine (free and total), chlorine dioxide, chlorite and peracetic acid (PAA) in water. You can read our post on the feature of the Kemio here.Â

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...
The quality of water used has a huge effect on the quality of the beer produced. Several different parameters are key when brewing, all of which have different effects on the final product. For example Sulphate brings out the bitterness in hops, Chloride can enhance the flavour in low concentrations, but can give a medical taste in high amounts, and Calcium lowers the pH which contribute...
The popular MD610 portable multiparameter photometer is now available with Bluetooth connectivity, for transferring the results to a smart phone or tablet. The free of charge app is compatible with Android or iOS systems.

Answer: Total Dissolved Solids (TDS) is a measure of the combined content of all the inorganic and organic substances such as mobile charged ions, minerals, salts or dissolved metals in a volume of liquid. Normally TDS is used in water testing, where TDS is defined as anything present that is not pure water (H2O) molecule or suspended solids. Finding out the exact amount of TDS in water ...

There is a standard USB A to B cable in the kit supplied with the Palintest 7500. Â When you plug the instrument into a PC then it will then act just like a flash drive and you can drag the 7500log.txt file onto the PC. This text file ca...
Total Base Number (TBN):
[caption id="attachment_5071" align="aligncenter" width="199"] Testing Oil samples[/caption]
Total Base Number (TBN) is the measure of the quantity of basic components in a petrochemical sample. TBN is determined in both new and used oils and is a value of the oil’s ability to neutralize the acids produced in the oils during normal use. The higher the TBN value of an ...
Total Acid Number (TAN):
[caption id="attachment_5085" align="aligncenter" width="300"] Oil testing[/caption]
Total Acid Number (TAN) is a measure of the quantity of acidic compounds present in a petrochemical sample. The TAN value is determined for both new and used oil samples. New oils are monitored to ensure the initial quality of the oil meets the specific TAN range for the sample type. U...
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...
