Super low temperature water bath, high and low temperature constant temperature water bath

Super low-temperature water bathIt is a high-precision constant temperature bath, and the super low temperature water bath is widely used in research departments such as chemical engineering and physical property testing, such as the softening point test of ductility tester molds and the constant temperature of needle insertion sample dishes. The components of the super low-temperature water bath are made of stainless steel, with the upper part being the electrical control part, the right part inside the box being the working water tank, and the left part being the temperature controlled refrigeration system. The water bath has a sealed coil inside, and the overall appearance is lightweight and beautiful, easy to operate, and the temperature changes quickly.

Marking anti reflection coefficient measuring instrumentOverview

By using DELTA's gradient refractive index and * * * optical system, various types of smooth and cross-sectional markings can be measured. The sensor response complies with CIE (Commission on Illumination) human eye response and A light source requirements, as well as CEN and ASTM requirements for cross-sectional height and color.

The anti reflection coefficient measuring instrument for marking lines is designed using professional optical and sensor technology with new development levels, and is a robust, durable, and good instrument equipment.

Features of the Marking Reverse Reflection Coefficient Measuring Instrument:

1. RL (nighttime visibility) and Qd (daytime visibility) in dry and humid environments

2. Short time measurement of 1-3 seconds

3. Measure smooth and cross-sectional markings up to 5mm

4. Memory with over 200000 measurement records

5. Multi language menu

6. Color LED display, easy to read data

7. Display and store date, time, humidity, and temperature

8. Convenient insertion and storage of road IDs, marking types, and user IDs

9. Easy to obtain the average value of measurement results

10. The humidity timer is convenient for measuring wet road markings

11. Free maintenance of LED lights as a gift

12. With high precision, various road markings can be measured at a simulated distance of 30 meters.

13. The reproducibility is+/-5%, and the repeatability is+/-2%.

14. Measure RL (nighttime visibility), Qd (daytime visibility), visibility in dry, humid, and continuous rainy environments according to the selected mode

15. Measure white and yellow markings without adjustment

16. There is automatic stray light compensation, which ensures that daytime and other light sources do not affect the accuracy of the measurement results.

17. The road sensor control software (RSC) combined with USB interface can easily download data and generate reports such as EXCEL.

18. GPS data can be easily converted to GPS programs such as Google Maps, which can visually display the locations that have been measured.

Marking anti reflection coefficient measuring instrumentCompliant with the following standards EN 1436 and ASTM E1710 "Transportation Industry Standard JT/T612-2004 of the People's Republic of China" for retro reflection measuring instruments.
