Moisture Analyser Suppliers

A small sample of a substance is placed in the moisture analyser and weighed. The substance is then heated to dry it out and then it’s weighed again. Simple math is then used to subtract the dry weight from the initial weight to determine the moisture content. 

It’s not rocket science, but it’s both accurate and effective. Most units will have a computer interface for observing and analysing the sample before and after the drying process.

• Food manufacturers. Moisture analysers are a critical component in both food product development and ongoing quality assurance. Just because one shipment of custard powder has the right moisture content doesn’t mean the next one will. Moisture analysis is therefore a critical day-by-day component of food manufacturing procedures. 
• Pharmaceutical companies. The efficacy of drugs or, more specifically, pills is clearly crucial for companies manufacturing them, doctors prescribing them and patients taking them. The right moisture content analysis is an essential part of the process to ensure drugs do exactly what they’re designed to do. 
• Oil and gas companies. Moisture analysers are used by major oil and gas companies to measure moisture in hydrocarbons and for analysing such things as natural gas and petrochemicals.

• Halogen 
• Infrared
• Glass-free metal heaters

Definitely. Moisture analysers are faster than ovens and complete the measuring process in fewer steps meaning there’s less chance for errors. Equally importantly, moisture analysers can be hooked up to computers and printers for easy data evaluation. 

Moisture analysers are also far more portable than ovens.

There are almost as many moisture analysers on the market as there are substances to analyse. So it’s important to compare specifications in great detail. You also need to consider factors that can’t be accurately assessed off a spec sheet, such as how easy the unit is to use in a real time sampling environment. 

With that in mind, here are the main questions to ask when choosing a moisture analyser:

• What are the sample types and substance characteristics the unit needs to analyse?
• Is the unit operator-friendly and easy to use on a repetitive basis?
• How does the unit process data?
• Does the unit have a computer interface?
• What optional accessories are available for the unit?
• Does the unit come with speedy service and support?

There’s more to a moisture analyser than meets the eye as they are highly calibrated and offer analysts the benefit of the most minuscule variations. So prices start at around $2,500 and can go over $4,000 with an average price of around $3,400.

Basically, there’s one primary problem - Ignoring temperature calibration. 

It’s an easy mistake to make as the essential function of a moisture analyser is to weigh samples before and after heating. As a result, operators can focus solely on ensuring the weight calibrations remain accurate while temperature goes haywire. If the sample dries too fast or too slow due to undetected temperature problems, the ensuing analysis can be wildly inaccurate. 

Regularly check to make sure the unit’s temperature is calibrated correctly.

If a moisture analyser isn’t properly maintained, the accuracy of sample readings suffer. First and foremost, keep your moisture analyser clean.

• Position the unit safely away from dust, dirt, temperature shifts and drafts
• Remove any residue from the unit immediately after each measurement
• Wash the sample dish, dish retainer, sample dish holder, draft shield and base plate using a soft cloth, water and mild dishwashing liquid, and then…
• Wipe each part with a soft cloth dampened with fresh water, and then…
• Dry each part thoroughly with a soft, dry cloth
• Avoid moving the unit as this can throw out weight and temperature calibrations
• Ideally, leave the maintenance of temperature sensors to technicians
