No. Zydax sensors utilize patent pending technology that correctly reads salt crystals as dry, while detecting even minimal amounts of moisture. The photo below shows the wet/dry portion of a T2WD Sensor with salt crystals present. The sensor reported dry.

This question needs to be answered in terms of the product design and not the brand name. As we all know, there are many brand names of products with varying amounts and types of commonly used ingredients.
We have tested many different products where sodium chloride, sodium acetate, magnesium chloride, and calcium chloride were the primary ingredients. We have also tested products where the primary ingredient was Calcium Magnesium Acetate (CMA) or potassium acetate. Additionally, we have tested these various deicer components in various mixtures with each other, both with and without corrosion inhibitors. What we have found from the extensive testing to date is that the Zydax Intelligent Sensor can not only see them, but can also accurately report the freeze point of different blends at different concentrations.
Zydax is very confident that Zydax Intelligent Sensors can detect and report accurate information about whatever product you are using. Also, with the benefits of both the active and passive sensor abilities in one unit (ZAPSS) combined with the intelligence inherent in the ZAPSS, we are able to accurately deliver freeze point information on a brine that may be present on the sensor, even if we don't know what it is.
If you have a specific product that you have concerns about, targeted product testing can be arranged by contacting Zydax. Testing may be done as a part of the sensor purchase process or for a fee. In same cases both may apply. The requester will be required to supply Zydax with a sample of the product (minimum 16 ounces) with complete data sheets listing its components, in what quantities, and a phase curve for the product. Arrangements for the product testing by Zydax must be made in advance of sample shipment.

Zydax sensors can be used to monitor surface and other environmental conditions in many different applications.
Our sensors offer the critical, maintenance oriented information that, in the past, was only availble through RPU based systems that could cost $50,000 or more. A Zydax system can cost as little as 10% of that amount.
The low cost and flexibility of Zydax sensors makes it possible to deploy our systems in many applications where traditional systems were just too expensive.
