Standard products usually ship within 7–15 working days. Custom configurations typically take 15–25 working days depending on specification and quantity. We confirm the exact schedule with your quotation.

Our factory is ISO 9001 certified. SF6 density relays are EMC-tested to the IEC 61000-4 series and sealed to a helium-tested leakage rate of ≤1×10⁻⁸ Pa·m³/s. CE declarations are available, and ATEX can be supported on request. Certificates and type-test reports are provided with orders.

We commonly work with T/T (bank transfer); other terms can be discussed for repeat or project orders. Quotations state terms clearly with no hidden costs.
We export worldwide by courier (DHL/FedEx/UPS) for samples and small orders, and by air or sea freight for volume orders — with export packing designed for instruments. We can ship EXW, FOB or CIF according to your preference.
Products are covered by a standard manufacturer warranty against defects. Because you buy factory-direct, engineering support comes straight from the people who build the instruments — usually within 24 hours.
