Haze&Transmittance Meter
   WGT-S Light transmittance / haze meter is applicable for light transmission rate / fog density measurement of all transparent or semi-transparent samples with a parallel surface (plastic plates, and sheets, etc), as well as turbidity or clarity determination of liquid samples (water, and drinks, etc.). The technical design meets the requirements of relevant standards, such as GB2410-80, ASTMD1033-61 (1997), and JISK7105-81, etc. The instrument adopted a method of automatic micro-computer operation. It is convenient for use, and may display light transmission rate and fog density at the same time. There is a standard printer interface on it.

WGT-S Character: 

1. Product could meet GB2410-80, ASTMD1003-61(1997), JISK7105-81 production standard, which could reach abroad technology.

2. Use parallel illumination, semi sphere scattering, integrating sphere 

photoelectric reception method.

3. Use micro computer automatically control and data processing system, 

no button to use, convenient to operate, have standard printer interface.

4. Automatically display light transmittance/ fog density average figure among

several testing, light transmittance accuracy to 0.1%fog density accuracy display to 0.01%

5. No zero drift, output data reliable.

6. Special design for the opened mode sample window, not influenced by sample

 size limitation, quick getting result.

7. Use modulator, machine not influenced by surrounding light, not need to be

 dark room, guarantee operator safety especially testing large samples.

8. Micro computer electronic circuit, high accuracy.

9. Have standard printer interface, could connect printer.

10. Have film magnetic fixture and sample cup, bring customer convenience to use.

11. Have a piece of haze plate, easy to check machine function.
