The testo 755 current and voltage tester

For those in the heating, ventilation and air-conditioning industry, a tool that offers total functionality across the entire range of measurement processes hasn’t existed; until now.

The testo 755 family is the first current and voltage tester range of its kind, offering the automatic measurement of voltage, resistance and current. With these readings accounting for around 70 per cent of all HVAC contractor applications, having a single device that doesn’t require the inclusion of additional tools for current calculation can be of great assistance to HVAC professionals.

Automatic detection for error prevention

The testo 755 range does everything on its own – able to detect the measurement objective of the user, the tool automatically takes readings without the need for the operator to press anything. Both testo 755 products offer this automatic detection, giving dependable, accurate readings and ensuring the prevention of selecting the wrong measurement type.

According to the electrical standard EN 61243-3:2010, all voltage testers must provide the ability to detect voltage even without battery power. To address this need, the testo 755 family is equipped with a special red LED, providing accurate and safe voltage results at all times.

The testo 755-2 product also offers rotating magnetic field testing and a voltage measurement range of up to 1,000 V – with automatic recognition activating when a current reaches and exceeds 6 V. Both the testo 755-1 and 755-2 provide current and resistance measuring up to 200 A and 100 kilohms, respectively.

Another feature of the testo 755 family lessens the dangers posed to HVAC and other professionals when working around electricity in darkened spaces. The inclusion of a built-in flashlight means that, even when working in dark or poorly lit conditions, you can rely on the testo 755 for safe electrical readings.

No replacement necessary

A common issue experienced when using a single tool or product can be early erosion or damage. The testo 755 range is equipped with removable and replaceable test leads – when the tips of these leads become damaged, the user can simply order a replacement tip, rather than an entirely new tool. This not only means you can still use the testo 755, but not having to purchase a replacement device will save on costs.
