Automated Moisture Analyzer


Nine samples. 40 minutes. Zero busywork. Other loss on drying methods require hours of shuffling samples in and out of machines. The ROS 1 automates the monotony, freeing you to do more profitable work.

Forget about it.

Analyze as many as nine samples at once. Once you fill the sample cups and press start, the ROS 1 takes care of the rest. 

It collects extensive data, enters it into a spreadsheet, creates a live drydown curve, and safely ends the test – all automatically, with no supervision necessary.


samples at once

World-class analysis.

ROS 1 heats samples, but it’s far more than a drying oven or moisture balance. Its unique heat source gently and precisely raises the sample’s temperature, vaporizing moisture without scorching or burning. 

As samples dry, they’re cycled across a highly accurate scale that records changes as small as 1/1000th of a gram. It’s MC analysis at its best: Precise, repeatable, reliable.


MC readability  

High heat ≠ high speed. Scorched samples give bad data. Unlike other methods, ROS 1 is both quick and accurate, thanks to predictive software and a unique heating element.


No spilled samples or fat fingered data.

ROS 1 and its companion app, Bridge, eliminate the time-consuming work and long experience needed to collect precise MC data. There’s no need to record or weigh anything. Interaction with samples is minimal. The machine does the work. 


Insights that moisture balances and ovens can’t detect.

Where moisture balances burn samples under imprecise halogen bulbs, the ROS 1 gently heats the sample itself, not the chamber. That means the ROS 1 moisture analyzer for food offers the exact temperatures of a drying oven paired with automated, accurate weighing and remarkable speed. 

Any sample, always accurate

92% of the top 100 food companies use METER devices. Throughout formulation, production and QA — from raw ingredients to final product and anything between.

Efficient, human-centric design 

METER’s easy-to-use and beautiful products win design awards across the globe. Device training is simple, operation is intuitive, and the resulting productivity gains are invaluable.

In the lead for 40 years

Since our founding in 1983, we’ve stayed laser-focused on moisture management science – and built the industry’s largest body of expertise on the topic.

Quick ROI

Reliably accurate moisture measurements allow tighter process controls, saving you money on energy bills, reducing risk, preventing rework and maximizing yield.

Feature summary

Conform with AOAC, ASTM, ISO — Dry to a constant weight or enter a time and temperature for your test

No method development —Patented software and breakthrough algorithms make the ROS 1 completely sample agnostic

Automate busywork — ROS 1 tracks and graphs sample weight, temperature and test time

Rapid testing, high throughput — Measure up to nine samples at once in 40 minutes or less – about four minutes per sample

Simple operation — Included Bridge desktop app makes taking readings and exporting results quick and intuitive

Precise results — High-grade integrated scale, exact temperature control and patented vapor pressure correction software ensure quality readings

Highly repeatable — Consistent and exact control of each relevant parameter 

Auto dry-detection — As evaporation slows, the ROS 1 weighs samples more and more frequently, then stops precisely when the sample is dry
