Testo AG has introduced a set of fi ve instruments for measurements on electrical appliances and systems. These include a digital multimeter in three versions, which recognizes the measurement parameters by socket use. Three clamp meter models have also been launched, with clamp mechanism for measuring tight-fi tting cables available with two current-voltage testers that fulfil the newest voltage tester standard and allows selection of measurement parameters automatically, without the risk of confusion. Completing the range are three voltage testers equipped with an all-round LED display which can be read from any position – and a non-contact voltage tester with a filter for high-frequency interference. With the introduction of these electrical measuring instruments, Testo now offers portable and stationary measurement solutions for almost all areas of application for HVAC&R.
