The Optris CSvision R1M two-color pyrometer stands out for its ability to deliver consistent and repeatable results. Unlike single-color pyrometers, which rely solely on intensity measurements, the CSvision R1M utilizes a ratio-based approach, measuring infrared radiation at two closely spaced wavelengths. This method provides unparalleled accuracy, particularly as temperatures rise and an object’s emitted radiation increases across the wavelength range.
One key advantage of the CSvision R1M is its reliability in adverse conditions. Unlike single-color devices, this pyrometer can provide accurate results even when emissivity is unknown or changes with temperature. This is especially beneficial when the measuring spot is partially on the object or when the object is smaller than the pyrometer spot size.
The two-color measurement principle of the CSvision R1M 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 95 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.
The CS Vision series’ innovative video sighting and crosshair laser make aligning the sensor easy. The CSvision R1M also features 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 makes the pyrometer suitable for various applications, enabling users to focus on targets at various distances.
The CSvision R1M offers a wide temperature measurement range from 550 °C to 3500 °C, with superior optical resolution up to 150:1. The infrared thermometers’ internal motorized focus enables contactless measurements from variable distances. Moreover, 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), ensuring reliable temperature measurements even in demanding industrial environments.
With flexibility in temperature ranges and 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, the CSvision R1M is adaptable to diverse industrial settings. The rugged design of the infrared pyrometers and German manufacturing ensure durability and accuracy, making it an ideal tool for critical temperature control in industries like metal and semiconductor manufacturing. The Optris CSvision R1M sets a high standard for 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).
