Frequently Asked Questions (FAQ)
-
Can this rod be used for high-viscosity liquids like oil or syrup?
Yes, the ball tip design helps reduce liquid adherence, but for very viscous products, we recommend a larger ball tip or a flat tip to minimize drag. Contact us for custom options. -
Is the rod fully extendable to exactly 3 meters?
The adjustable length range is designed to cover 0.5m to 3m. The rod consists of multiple sections that can be assembled or telescoped; the maximum length is 3.0m. Please specify if you need a different maximum length. -
What is the thread standard? Can I use it with BSP threads?
Our standard is 1/2" NPT (National Pipe Thread). If you require BSP or other thread types, we can produce custom threads upon request. -
How is the scale marked? Is it accurate?
The scale is laser-engraved for high durability and readability. Accuracy is ±1mm per meter. We can provide imperial or metric scales as per your preference. -
Do you offer certificates of material or calibration?
Yes, we can provide a certificate of material (304 SS) and a calibration certificate for the rod length upon request. Please note that this is a customized service. -
What is the packing method? Can I get samples before bulk order?
Standard packing includes individual polybags and foam padding inside cartons. Sample orders are welcome; we can ship a single rod for evaluation. Lead time for samples is 5–7 days. -
Can the rod be used for underground storage tanks?
Yes, as long as the tank opening is at least 1/2" NPT compatible. The adjustable length makes it suitable for varying tank depths. For underground tanks, ensure the rod is long enough to reach the bottom. -
What is the warranty period?
We offer a 12-month warranty against manufacturing defects. For any issues, our technical team will provide remote support or replacement parts.
