I'm in the market for a hand-held laser remote methane gas leak detector and would like to request a quotation for your current pricing. Specifically, I'm interested in understanding the cost details along with any potential discounts for bulk orders. If possible, please include information about the additional features or specifications of the product that may be relevant to our usage. In addition to the pricing, it would be helpful if you could provide details on the lead time for shipping, warranty terms, and after-sales support options. We're looking to make a decision soon, so any information you can provide would be greatly appreciated. Thank you!
