Olt Stick - the original and still the best non-contact voltage tester range - has now launched the unique VSPU-1 Proving Unit - designed to provide even greater safety and peace of mind for electrical, gas and utilities engineers - and everyone else wise enough to keep a Volt Stick tester close to hand. Initially developed to meet the most stringent Health & Safety policies and requirements of the UK's major utilities providers and public sector engineers, Sagab's new VSPU-1 Proving Unit is specifically designed to provide confident functionality testing of the Volt Stick 230v product range (Volt Stick 230Y, 230B, SOUND and LV50 models).
