How to choose a pyrometer
The question often arises as to which pyrometer is better to buy. Main selection criteria:
- Classification. The mechanism of establishment of devices can be different. You can find optical, brightness, spectral and radiation devices. The most popular is the infrared pyrometer.
- Appointment. Stationary and portable models are available for purchase. In certain areas of production, it is advisable to use pyrometers that are fixed in a specific place and operate from a standard network. They are distinguished by increased accuracy and reliability. It is advisable to make periodic measurements of temperature indicators at various points of the company or construction site using a mobile device. Less accuracy is compensated by its compact size and lightness.
- Temperature range. Taking into account production needs, products with a specific temperature range are selected. Universal pyrometers determine negative and positive temperatures. For workers in metallurgical enterprises, it is advisable to focus on the range of 50-2000 degrees, and for utility workers, -50 + 50 is suitable.
- Range of exposure. Not in all cases is it safe to capture data near the object under study. Therefore, it is required to take into account the distance from which the device determines the temperature indicators. Optical resolution will be an important criterion. It will show the ratio of the distance to the object, its dimensions. The temperature indicators of the product are measured shortly with sighting from 1: 1 to 20: 1. The long focus is from 30: 1 to 100: 1.
- Accuracy. Each device has a measurement error ranging from 0.5 degrees to 3-4%. Optimum accuracy is 1-3 degrees.
- Measurement speed. You should not be in certain places for a long time. Therefore, the device must very quickly determine the temperature indicators. A product with a response speed of 0.25-0.5 seconds is suitable for everyday life. In higher-speed models, this parameter fluctuates in the range of 0.1-0.15 seconds.
- Additional functionality. The price of the device will depend on the key characteristics and the presence of auxiliary functions. Some products detect humidity, others record data on a video camera. Useful functions will be the presence of a laser pointer, monitor lighting, data storage in memory.
To get the best pyrometer for measuring temperature, you need to consider these recommendations.
