The Optris CSvision R2M two-color pyrometer offers consistent and repeatable results, excelling in capturing changes in emitted radiation as temperatures rise. Unlike single-color pyrometers, which rely solely on intensity measurements, the CSvision R2M measures infrared radiation at two closely spaced wavelengths, providing unparalleled accuracy.
One standout feature of the CSvision R2M is its ability to deliver reliable measurements in adverse conditions. Unlike single-color devices, a ratio pyrometer can provide accurate results even when emissivity is unknown or changes with temperature. This versatility is particularly useful when the measuring spot is not fully on the object or when the object is smaller than the pyrometer spot size.
The two-color measurement principle of the CSvision R2M ensures repeatable and accurate measurements under varying conditions, offering resistance to dust, smoke, steam, and dirty observation windows. The infrared sensor remains reliable even with up to 90 percent attenuation caused by changing transmissions in the optical path. Additionally, this approach allows precise temperature measurements when the object is not fully placed on the pyrometer spot or is in rapid motion.
Aligning the sensor with the CSvision R2M series’s innovative video sighting and crosshair laser is effortless. The switchable two-step brightness reduction filter further enhances visibility, making the pyrometer easy to focus on bright objects.
Another notable feature of the CSvision R2M is its motorized focus capability, allowing for adjustable focusing from 350 mm to infinity in the standard focus version and 200mm to 400mm in the close focus version. This flexibility enables users to easily focus on targets at various distances. The optical resolution of the CSvision R2M is 75:1.
The CSvision R2M offers a wide temperature measurement range from 250 °C to 1400 °C, with a superior optical resolution of up to 75:1. The internal motorized focus enables contactless measurements from variable distances. Additionally, the device’s system accuracy, measured at an ambient temperature of 23 ± 5 °C, is highly precise, with a deviation of only ±(0.5% of the reading + 2 °C). This level of accuracy ensures reliable temperature measurements even in demanding industrial environments. Moreover, the pyrometers repeatability, measured at an ambient temperature of 23 ±5 °C, is ±0.3% of the reading, guaranteeing consistent performance over repeated measurements.
The CSvision R2M supports various analog and digital outputs, including 2x 0/4 – 20 mA, 0 – 5 V, 0 – 10 V, USB, RS485, Modbus TCP, ProfiNet, and Ethernet IP, providing flexibility in integration. The infrared thermometers adaptability to adverse environments, operating from 0 °C to 65 °C without additional cooling, further enhances its utility.
Manufactured in Germany, the CSvision R2M’s rugged design makes it suitable for critical temperature control in industrial manufacturing applications. Industries such as metal and semiconductor manufacturing benefit from its adaptability, durability, and accuracy, ensuring precise temperature measurements in challenging environments. The Optris CSvision R2M is a reliable choice for those seeking excellence in non-contact temperature sensing technology.

Thermography software optris PIX Connect is included and license-free.All infrared cameras are delivered with the thermography software optris PIX Connect, developed specifically for the extensive documentation and analysis of thermal images. The Windows-based PIX Connect software enables users to tailor the infrared cameras to meet specific requirements. It analyses live and recorded temperature data and triggers alarm signals for process integration. The key to leveraging the Optris infrared camera is a correct configuration. This includes detailed device-specific configurations such as frame rate, measurement range adjustments, external communication settings, and USB/Ethernet configurations. Moreover, PIX Connect facilitates firmware updates and the download of configuration files over the Internet.
Optris offers several different SDKs for our Xi and PI thermal imaging cameras. Depending on the operating platform, the infrared camera, the coding language, and the hardware platform, different software interfaces can be utilized:
The Optris IRmobile allows users to set up and commission an Optris infrared pyrometer or infrared camera with an Android smartphone or tablet. This tool becomes handy for commissioning and aligning the infrared camera’s field of view or adjusting the configuration. The app analyzes the connected infrared camera‘s live infrared image stream with auto hot and cold spot detection. For pyrometers, a temperature-time diagram or the video signal is displayed. This app works on most Android devices running 5.0+ with a USB port supporting USB-OTG (On The Go).
