Qualitest products ship internationally from the United States directly to your New Zealand address. Most orders dispatch within 5-10 business days of order placement. Estimated delivery to New Zealand is 10-20 business days from dispatch, depending on freight mode, customs clearance, and carrier schedules.

Delivery timeframes for larger or heavier items may vary. Some products may be subject to extended lead times depending on stock availability at the time of order. For time-sensitive orders, contact us before purchasing to confirm current lead time.

Returns & warranty

Qualitest products are covered by manufacturer warranties against defects in materials and workmanship. Warranty periods vary by product - many instruments in the Qualitest range carry a 12-month manufacturer warranty, and selected products such as the Qualitest CMX ultrasonic thickness gauge series carry a 2-year warranty. Contact us for specific warranty details for the product you are purchasing.

Returns are accepted within 30 days of delivery for products in original, unused condition with all original packaging and accessories intact. Due to the international nature of these shipments, return freight costs are the responsibility of the buyer unless the item arrived damaged or was incorrectly supplied. Items that have been used, installed, calibrated, or modified are not eligible for return.

For warranty claims or return requests, contact us at sales@testingcore.com or call 09 558 3100.

The QualiSurf II is a surface roughness tester suited to scientific labs, factory metrology rooms, and out on the work site. It measures surface roughness on a range of machining components, with 45 selectable roughness units to choose from (Ra, Rz, and others), and stores both results and surface profile on the unit before sending them to a PC.

We also carry the QualiSurf II-S alongside the standard II - it uses an external transducer on an extended connection cable, which makes it a better fit for measuring roughness inside pipes and tubes.

  • Multi-parameter measuring - 45 selectable roughness units, including Ra, Rp, Rv, Rt, Rz, Rq, Rsk, Rku, Rc, and more
  • Touch screen / TFT colour LED display
  • High-accuracy inductance pickup
  • 2RC and GAUSS filtering methods
  • Meets ISO 1997, ANSI, and JIS 2001 standards
  • Shows all parameter values and graphs after each measurement
  • Connects to a PC or mini printer to print parameters and graphs
  • Both USB and RS232 interfaces
  • Automatic switch-off
