Buyer questions

Q: Is the digital temperature tester safe to use near electrical circuits?
Yes, the device does not have its own power sources that could cause a short circuit. It only uses batteries and a sensor clamp. However, follow safety rules and do not touch high-voltage parts. The device has a low voltage of 4.5 V, making it completely safe with electricity.

Q: How long do the batteries last, and are they easy to replace?
The batteries will last for several months during regular use because the current consumption is low—less than 30 mA. Replacing the batteries is very easy: open the bottom part, remove the old 1.5 V cells, and insert new ones in their place. No professional help or special tools are required.

Q: Does the device come with a storage case and a warranty?
Yes, the AUTOOL LM55 package includes a protective case, which is convenient for carrying and storage. The product has a standard 12-month manufacturer's warranty that covers manufacturing defects. If the device malfunctions during this time, please read the seller's return policy.

The AUTOOL LM55 digital temperature tester is an indispensable tool for professionals and enthusiasts.
