Often used for chemical feed, these scales typically weigh Chlorine and SO2 one ton cylinders. They must be corrosion resistant for this type of environment. They also must be very rugged to handle tough tank loading and at the same time, remain accurate.

Extremely Durable Chlorine Scales

Most “Tonner” scales are constructed from welded steel with a powder coated finish. In most cases, that is usually enough until the paint gets scratched, leaving an opening for corrosion to migrate under the coating. Arlyn's Chlorine Ton Scales are constructed from stainless steel, greatly reducing corrosion and providing longer, trouble free life.

Very Accurate

The industry standard for Chlorine Ton Cylinder Scales is to apply the weight to a single load cell through a pivot and lever system. This construction presents a number of problems. First of all, this is an old weighing method that is susceptible to inaccuracies as the pivots wear. Any change in position of the tank will alter the weight. Instead, the Arlyn's Ton Scales uses four (4) heat treated, abuse resistant stainless steel load cells. There are absolutely no pivots and levers to degrade over time. Accuracy is as much as five times better!

Versatile Connectivity & Output Options

A variety of optional outputs are available for seamless connectivity. For PLC, 4-20mA analog signals are an industry standard. Other analog signals include 0-5V and 1-5V. Modbus RTU, ASCII or TCP is also available. In fact, with the optional Arlyn UpScale Touchscreen Indicator (equipped with Wi-Fi connectivity), cloud monitoring and data logging also becomes possible. See the Available Upgrades table below for a list of available options.

Monitor and Track your industrial scales on the cloud, anywhere on any device using the new AxChange Cloud Monitoring and Weight Tracking system. Limited free beta accounts available.

Intrinsically Safe Versions Available

For hazardous or classified environments, we also manufacture Intrinsically Safe Chlorine Ton Scales equipped with FM Approved display indicator and stainless steel load cell sensors. See our ArlynGuard T Product line or contact us at (800) 645-4301 for more details.

Low Cost

Although the features and performance would suggest otherwise, Arlyn’s Factory Direct sales channel and in house design and fabrication capability result in a lower cost.
