The Extech EX845 provides TRMS AC/DC Current & Voltage measurements upto 1000A and 1000V respectively and has a built-in non-contact IR Thermometer with a laser pointer that is capable of measuring upto 270C. However the real benefit of the Extech EX845 is the Bluetooth transmitter with MeterLink technology that allows this clamp meter to wirelessly communicate with a wide range of Flir Thermal Imaging Cameras including the new E-Series. Valuable voltage and current readings can be wirelessly transmitted to a Flir infrared camera and be integrated with the thermal images to provide a comprehensive overview of an electrical system.

A Flir IR camera can quickly identify problems on electrical systems and provide infrared images which clearly locate the specific component with the fault. Using MeterLink the Extech EX845 allows a thermographer to quickly take an electrical readings on the faulty component and instantly record them on the thermal image they have just taken. In addition the EX845 clampmeter has a CAT IV 600V safety rating for added protection and making it suitable for industrial applications. The EX845 jaw opening size of 43mm will fit conductors up to 750MCM or two 500MCM. The TRMS feature ensures highly accurate readings of non-sinusoidal waveforms and the peak hold function can be used to capture inrush currents and Transients.
