Product Warranty Policy

Product Warranty

Warranty period

In general, Hioki products are covered by a three-year warranty (some exceptions apply).
Warranty was extended in April 2018 (from one to three years) and it is applied to products with serial numbers since April 2018.

Warranty terms

In the event Hioki is responsible for the failure of a product during the warranty period beginning on the date of purchase (or beginning in the month the product was manufactured if the date of purchase is unclear), we will repair or replace the product free of charge.

Warranty scope

The specifications, performance, and functionality of Hioki products are primarily verified on a standalone basis. Although we verify that products operate properly when connected to standard options, you are responsible for verifying proper operation while connected to products from other manufacturers. The scope of Hioki’s warranty is limited to Hioki products. Connected devices and issues caused by connected devices are considered outside the scope of the warranty. In the event of physical damage, any compensation that might be provided by Hioki is limited to the purchase price of the product.

Accuracy guarantee

For products with an accuracy guarantee, we guarantee the level of accuracy indicated in the specifications for a certain period of time following shipment from the factory. In the event of an accuracy defect during that period of time, we will adjust the product free of charge.

Consumables and parts with a limited service life

Consumables and parts with a limited service life are not covered by product warranties. Such parts must be replaced as part of periodic maintenance in order to ensure the product can be used in a stable manner over the long term. Please see the Maximizing Performance page.

Consumables

It is recommended to replace consumables, which include single-use supplies such as recording paper and batteries as well as components such as probes that degrade over time due to bending and tensile force, on regular basis. Parts like probes, which incorporate tip pins, connectors, and cables, are also considered consumables.

Examples: Batteries, probes, test leads, cables, temperature and humidity sensors, thermocouples, recording paper, and dry cells

Exceptions: Consumables that are covered by the product warranty

Consumables that comprise a significant portion of the product and account for a majority of its product value are covered by product warranties. However, connectors and cables are not covered by product warranties.

Examples: Current sensors, clamp-on probes

Parts with a limited service life

The amount of time for which parts with a limited service life can be used may decrease due to deterioration or wear caused by factors such as frequency of use, passage of time, and the operating environment (temperature, humidity, etc.). Such parts must be replaced as part of periodic maintenance in order to ensure the product can be used in a stable manner over the long term.

Examples: Displays, backlights, disk drives, power supply units, fans, aluminum electrolytic capacitors, and relays
