Service
1. Longlv provides customers with remote installation and debugging services, as well as other technical consultations. When necessary, technicians can provide on-site technical training. If customers have any technical questions, technicians will respond within 24 hours.
2. Longlv products are strictly designed and produced in accordance with the ISO9001 international quality system. Sensor products have a 1-year warranty. Instrument products have a 3-year warranty, 7-day return and exchange, and lifetime maintenance. (Man-made damage is not covered by the warranty, and customized products are not returned or exchanged without quality problems.)
3. For returns and exchanges due to quality problems, Longlv will bear the return and exchange freight. For returns and exchanges not due to quality problems, the customer will bear the cost. Note: Quality problems refer to customized parameters such as functions, dimensions, indicators, and installation methods that are not customized according to the customer's requirements, inconsistent functions, dimensional errors, and inaccurate precision (except within the error range). Customized products must be processed and produced after both parties confirm the drawings. If the product does not meet the customer's requirements, a written objection must be raised within two weeks. If the customer does not raise an objection within the prescribed period, it will be deemed to have passed the acceptance. If an objection is raised within the time limit, both parties confirm that it is indeed a product quality problem or it is not produced according to the requirements confirmed by both parties, it can be exchanged or refunded. If there is no quality problem, and the delivery model is complete and correct with the contract model, no return and exchange service will be provided.
4. The test results of products returned to the factory for repair will be issued within 3 working days, and the repair will be completed within 7 working days.
