Digital Turbidity Meter
Model No – NT 4000
Turbidity Meter – Advanced NT 4000 Model
The Turbidity Meter is an essential instrument in laboratories for measuring the cloudiness or haziness of liquids. Traditional turbidity meters often use incandescent lamps as light sources, which emit a broad spectrum of wavelengths. This wide range can cause colorimetric interference in turbidity readings. Additionally, incandescent lamp output tends to reduce over time, requiring frequent replacement of the lamp and recalibration.
NT 4000 Turbidity Meter with IR LED
The Spectralab Model NT 4000 Turbidity Meter overcomes these challenges by using a narrow band monochromatic IR LED light source. This design minimizes wavelength interference and offers a much longer life compared to incandescent lamps.
Microcontroller-Based Turbidity Meter
The NT 4000 Turbidity Meter is a benchtop and portable microcontroller-based instrument, built on nephelometric and ratiometric measurement principles. It uses LED technology and fully complies with EPA 180.1, ISO 7027, and the EPA GLI Method 2 (infrared ratio mode).
Features of the NT 4000 Turbidity Meter
- Memory to store up to 40 results
- Data transfer capability to PC for documentation and printing (with report number, date, and time)
- High accuracy with reduced wavelength interference
- Longer lamp life, reducing maintenance
