Q:  How do Temp-Plates work?

A: Temp-Plate temperature sensitive labels are adhesive labels with different temperature “spots” laminated between a heat resistant cover.  These temperature “spots” are made of a temperature sensitive chemical substance that has been designed to change at the marked temperature.

Q:  How do I store unused Temp-Plate labels?

A: All Temp-Plate labels should be stored in their original container. Temp-Plate Labels with indication points of 120°F (48°C) or below should be refrigerated upon receipt to prevent any temperature points from turning prematurely. Temp-Plate Labels with indication points above 120°F (48°C) should be stored at an average room temperature of 60°F (15.55°C) to 80°F (26.66°C) and relative humidity of 50%.

Q: What is the shelf life of a Temp-Plate?

A: Temp-plates are guaranteed to stick for a minimum of five years from date of manufacture when stored in their original container under the following conditions:

Temp-Plate Labels with indication points of 120°F (48°C) or below should be refrigerated upon receipt to prevent any temperature points from turning prematurely. Temp-Plate Labels with indication points above 120°F (48°C) should be stored at an average room temperature of 60°F (15.55°C) to 80°F (26.66°C) and relative humidity of 50%. If you install Temp-plates according to instructions and have any issue, return the remaining unused labels to us for a no charge replacement.  If it sticks – it works.

Q:  How do I install a Temp-Plate?

A: The surface to be monitored should be clean and dry. Peel backing material from Temp-Plate and press adhesive side firmly against the surface. Use fingers to smooth out all air bubbles beneath Temp-Plate.  Rated temperature has been reached when indicator point turns black.

Q:  What does NIST Traceable mean, and why should I care about it?

A: NIST stands for the National Institute of Standards and Technology, a United States organization that defines and standardizes measurements, among other things.

When we describe a label as being NIST Traceable, we mean that we maintain an unbroken chain of calibration records from the NIST standard measurement, all the way to your final finished label.  We maintain calibration records of every batch of  “spot” material we use, identifiable by lot number.  This unbroken chain of measurements from the NIST Standard, to our test equipment, to your Temp-Plate label produces a temperature measurement that is traceable back to NIST Standards.

What does this mean to you? You’re ensured a consistent and accurate temperature measurement every time.

Q: I want to use Temp-Plates in a less than clean environment.  Will they still work for me?

A: When Temp-Plates are properly installed, they will resist exposure to solvents, fuels, grease, oil, water, and steam.  Make sure your installation surface is clean and dry before applying.

Q: How do I remove a Temp-Plate Label from a surface?

A: That depends on what your Temp-Plate label is applied to.  You can often remove a Temp-Plate label with a fingernail. You can also use rubbing alcohol or a tape removal product, but be sure that any solvent you use will not damage your substrate.

Q: What is the Harmonized Tariff Code for Temp-Plate Labels?

A: Temp-Plate Labels are coded 9025.80.4000 in the Harmonized Tariff Schedule of the United States.

Q: Where can I find the SDS sheets for Temp-Plate Labels?

A: Visit our Downloads page to access SDS information in .pdf format on our Temp-Plate labels.

Q: When will my order ship?

A: While many models of Temp-Plates are in stock, some labels will have to be produced once we receive your order.  If your label is in stock, your order will ship in 2 to 3 days.  If your label must be produced, it could take up to 2 weeks for your order to ship.  If your order is time sensitive, please call us directly at 1-800-421-2853 so that we may help you make arrangements to meet your schedule.

Please note that low temperature Temp-Plates that have indication spots below 120°F (48°C) must be shipped via overnight service with an ice pack to ensure that the labels do not turn accidentally in transit.  These low temperature Temp-Plates are only shipped from our factory Monday – Thursday, unless Saturday delivery is requested.

Q: Why do my Temp-Plate labels have to ship overnight?

A: Wahl Temp-Plate Labels that have indication spots of 120°F (48°C) or below must be shipped via overnight service with an ice pack to ensure that the labels do not turn accidentally in transit.  As we can’t control the environments your Temp-Plates may encounter during the shipping process, we don’t know if they might end up in the back of a hot truck that could turn the temperature spots on the labels prematurely.  Domestic shipments of lower temperature labels are shipped via overnight service with an ice pack to guarantee your Temp-Plates arrive at your facility in the best possible condition.  International shipments must use Express or Priority service.  Low temperature Temp-Plates are only shipped from our factory Monday – Thursday, unless Saturday delivery is requested.

Q: Why will my shopping cart only let me choose Next Day Air Shipping?

A: If even one of your items is a low temperature label that requires overnight shipping, you will only be allowed to choose from overnight shipping methods when checking out.

Q: What forms of payment do you accept?

A: Our website accepts Credit Card payment only, via Visa, MasterCard, Discover, or American Express.  By contacting us directly at 1-800-421-2853 or sales (at) palmerwahl.com, customers can also arrange to be considered for an open account, or arrange payment via wire transfer.
