Had to replace a lamp, but the same was no longer available. Great advice, found a suitable replacement and delivered it quickly.

HT Instruments Test Equipment for Electrical Contractors

HT Instruments offers a broad test instrument portfolio covering the typical measurement tasks in electrical contracting: from straightforward voltage testing with a multimeter through complete installation verification with an installation tester to power quality analysis and earth resistance measurement. Test accessories such as safety inspection labels, crimping pliers and extension leads complete the range for documented test operations.

  Installer's tip: For periodic inspection to IEC 60364-6, a full installation tester is not always necessary. A multimeter with insulation measurement and a dedicated RCD and protective conductor tester cover most verification requirements. For contractors who regularly commission installations and need inspection records, an HT instrument set provides a matched combination of meter, accessories and clamps in a single package.

FAQ: HT Instruments

What does HT Instruments manufacture?

HT Instruments is a manufacturer of test instruments for electrical contractors and industry. The range includes multimeters, installation testers, clamp meters, residual current clamps, earth resistance clamps, power quality analysers, voltage testers, cable testers, lux meters and matching test accessories.

What does an HT installation tester check?

An HT installation tester checks electrical installations to the requirements of IEC 60364-6: insulation resistance, loop impedance, prospective short-circuit current, RCD trip time and current, and protective conductor continuity. It documents results for the inspection report and is the standard tool for initial and periodic installation verification.

What is an earth resistance clamp?

An earth resistance clamp measures the earth resistance of an earth electrode without disconnecting it from the earthing system. It clamps around the earth conductor and measures resistance contactlessly using an inductive method, allowing measurements during normal operation.

Which HT Instruments products are available at WATT24?

WATT24 stocks HT Instruments multimeters, installation testers, clamp meters, residual current clamps, earth resistance clamps, power quality analysers, phase data loggers, voltage testers, cable testers, LED lux meters, wall scanners, instrument sets, safety inspection labels, crimping pliers, safety test probes and extension leads.
