Trading since 1965, and known since 1987 as No Climb Products Ltd, we re-branded as 'detectortesters' in 2007 when the name 'No Climb' no longer focussed on our core activity.  We are the company behind the world leading Solo, Trutest, Chekkit, Scorpion, Testifire and Smoke Sabre smoke, heat and carbon monoxide (CO) detector testers.

Based on a small niche viable only on a global scale we sell all over the world and operate from both UK and USA.  Focussed on the design and manufacture of outstanding quality, innovative products we invest heavily in R & D, close technical and strategic alliances and strong customer service and support.  As a result, we enjoy trading partnerships with more than 90 countries worldwide - leading the market for our products in many of them.
