What is Prop 65?
In 1986, California voters approved an initiative to help them make informed decisions about the products they buy. That initiative became known as Proposition 65. Proposition 65 requires the state of California to publish a list of chemicals known to cause cancer/ reproductive harm. You can learn more about Prop 65 here.
Why do METER products have a Prop 65 warning?
METER is required by California law to post a warning on any product that might be sold in California if it contains or might contain one of the more than 900 chemicals known to the state of California to cause cancer and/or reproductive harm. Because consumers learn about our products from our website, we are required to post these warnings on the product web pages as well. California residents are used to seeing these notifications on many products, including household items, electrical wires, electronics, jewelry, dishes, flashlights, cosmetics, skincare products, and much more. People who live outside the state of California may be surprised and alarmed by these notifications. It is important to know that nearly all electronic products require the notification label even though the chemicals involved may only be potentially harmful when eaten in large quantities.
Are METER products safe?
A Prop 65 warning does not necessarily mean a product is in violation of any product safety standards or requirements. Because METER sources manufacturing materials from other suppliers, we provide the warning in order to acknowledge that METER products may contain one or more of the chemicals listed. However, it’s likely that those chemicals are in such small amounts that they fall into the no-significant-risk category. To be safe and compliant, we have elected to label all product web pages and packaging with this warning.
What types of chemicals are on the list?

- CONSUMABLES How long can I store the verification solutions?
The verification standards have an expiration date of one year. If your standards have reached the expiration date, you will need to order fresh standards as the standards can no longer be guaranteed to read within our specifications.
- CONSUMABLES Can I reuse the standards or sample cups?
The standards we use are unsaturated salt solutions, which are created with high accuracy and precision. They are not reusable, however, as exposure to ambient conditions will begin to alter the standards. If they are kept in a sample cup with a lid, they can be kept for up to two hours but no longer. The sample cups are meant to be disposable. Residue left behind from the previous sample can impact your readings and introduce error. Repeat washing of the cups breaks down the coating and material can become embedded in the plastic, which can also introduce error. For consistent and accurate results, we do not recommend reusing the cups.
