孟加拉采购需求：其他仪器,pH计

I'm interested in purchasing a specific type of pen-style pH meter, and I'm looking to buy 100 units for my upcoming project in Bangladesh. I'd like to know the pricing for this quantity, including any additional costs such as shipping or taxes. Additionally, it would be great if you could provide some details about the product, like its specifications and any warranty or after-sales support available. If possible, please let me know the lead time for delivery. Looking forward to your prompt response with the required information!
