Extech EX845 Meterlink clamp meter – transmits to FLIR IR cameras
By Anthony Capkun
Extech Instruments’ EX845 is a 1000A AC/DC CAT IV clamp meter with Meterlink technology and a built-in infrared thermometer. Meterlink is a technology that wirelessly connects FLIR infrared cameras to Extech meters via Bluetooth. Meterlink imprints electrical readings from the meter onto a related IR image from the camera. The 4-digit, 4000 count backlit display is complemented by several one-button functions including data hold, min/max, and selectable auto- or manual-ranging. The 1.7-in. jaw opening handles conductors up to 750MCM, or multiple conductors such as two 500MCM. The EX845 has a CAT IV-600V, CAT III-1000V over-voltage safety rating and is CE and ETL approved. It comes complete with an 8-piece test lead set, 9V battery, Type K temperature probe, and a belt holster.
