The first digital multimeter (DMM) in its RS PRO product range to feature a built-in thermal imager has been released by RS Components. The RS-9889 thermal imaging multimeter allows engineers to identify thermal overload issues in electrical equipment from a safe distance, without the need for any physical contact.

The multimeter is an all-in-one handheld device designed to combine durability and reliability with excellent value for money.

It is suitable for a wide variety of applications, ranging from smart manufacturing in the industrial automation sector, to general electrical tasks such as testing sockets and lighting during business safety audits and home renovations.

The features of a digital multimeter — measuring circuit parameters such as voltages, currents and resistances — are combined with an infrared thermal imaging camera to allow hot and cool points in electrical components to be identified on a viewable thermogram.

The thermal imager offers max, min and centre crosshair targeting to help the user identify and measure required temperature ranges easily.

A Bluetooth Low Energy (BLE) connection allows thermal images to be shared quickly to other devices via the Thermview+ app.

The thermal imager has a 2.8-inch colour TFT LCD screen with an infrared resolution of 80 x 80 pixels, a 21° x 21° field of view, thermal sensitivity (NETD or noise equivalent temperature difference) to less than 0.1°C/100mK, a fast 50Hz thermal image frame rate, an object temperature range from 20° to 260°C, a spectral range of 8–14μm, and accuracy to within ±2°C, or ±2% of the reading.

The versatile RS-9889 include also functions as a diode, resistance and continuity tester, equipped with a buzzer, and can measure temperatures all the way up to 1000°C using a K-type thermocouple probe. AC and AC+DC voltage and current are true RMS.

A lightweight portable device allowing users to work on the go, the RS-9889 measures just 80 x 58 x 195mm and weighs 540g. It is shipping now from RS in the EMEA and Asia Pacific regions.
