TN480 Waterproof Turbidity Meter Kit – IC-TN480

The Apera Instruments TN480 Portable Turbidity Meter is built with an infrared light source, using ISO7207 compliant nephelometric method (90 degrees), equipped with a large TFT colored screen, designed for reliable turbidity measurements from 0 to 1000 NTU in various applications both in-field and in-lab e.g. environmental monitoring, water treatment, beverage making, etc.
Supplied with calibration standards, three sample vials, polishing cloth, batteries, USB cable and silicone oil in hard carry case.
The standards have a guaranteed one-year shelf life even if you’ve opened the bottle and happened not to have recapped it tightly. The convenient submicron polymer suspensio
Features:
– Automatic calibration with progress bar, on-screen guide and low battery indicator, and automatic power off, etc.
– Autoranging from 0 to 1000 nephelometric turbidity units (NTU).
– Meets ISO 7027 (DIN EN 27027) performance criteria.
– Infrared light source – delivers laboratory accuracy.
– Data storage for 200 data sets
– USB port for data export
– 0.0 NTU Error Reminder: If the zero point is calibrated with contaminated 0.0 NTU standard solution, the measurement will have a negative error. The instrument can automatically recognize the negative error at the zero point and remind users to re-calibrate, as shown in the right figure. If the reminder appears again after calibration, it means that the 0.0 NTU standard solution is invalid and should be replaced.
– US EPA recognized standards are included in sealed vials.
– Large coloured TFT easy-to-read screen (blue backlight).
– Easy to use. Easy to calibrate.
– Modern design.
– Designed for the rigors of rugged field applications.
– Waterproof.
– Convenient rugged carrying case.
