Digital multimeter with thermal imager

23 October 2019 Test & Measurement

A digital multimeter (DMM) with a built-in thermal imager has been added to RS Components’ RS PRO product range. The RS-9889 allows engineers to identify thermal overload issues in electrical equipment from a safe distance, without the need for any physical contact. The instrument is an all-in-one handheld device designed, like other products in the RS PRO range, to combine durability and reliability with 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 RS-9889 combines features of a digital multimeter – measuring circuit parameters such as voltages, currents and resistances – 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 of the RS-9889 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/100 mK,

a fast 50 Hz thermal image frame rate, an object temperature range from 20°C to 260°C, a spectral range of 8–14 μm, and accuracy to within ±2°C, or ±2% of the reading.

The versatile RS-9889 also includes functions such as a diode, resistance and continuity tester, is 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 195 mm and weighs 540 g.
