IMH Technologies Ltd

IMH Technologies Ltd is the exclusive UK and Eire distributor for the Dranetz range of power quality monitors, Powerside (formerly Power Standards Lab) range of power monitors and Dent Instruments energy loggers. In addition, IMH represents the interests of Electrotek who are a specialist power quality analysis software company.

Formed in 1993, IMH Technologies Ltd applies nearly 30 years of experience, to offer an independent power quality consultancy service that has benefited major utilities and customers throughout the United Kingdom and offshore.

IMH offers a full repair and calibration service for our major products and is the European Service Centre for Dranetz portable instruments. Calibration to National Standards is performed at competitive prices. We are also experts in configuring our instruments with the latest 4G routers - that access the strongest mobile data signal for a given location - to give full remote control of our power monitors.
