I'm looking to purchase some horizontal measuring instruments in varying lengths. Specifically, I need 20 units each of 50m, 100m, and 150m models. Please provide your best pricing and availability for these items. Additionally, let me know about any warranty options and lead times for delivery. I'm eager to establish a good working relationship and would appreciate prompt feedback on this inquiry. Thank you!
