Hey, I looked into the Sper Scientific 860040 Turbidity Meter, and it seems like a solid pick for anyone who needs to measure turbidity, whether in the lab or out in the field. Although I couldn't find specific details about its measurement range, it does follow the ISO 7027 standards. That's typically used for nephelometric turbidity units (NTU), so it should work for a fair number of applications.

One thing that really stands out is its portability. The meter weighs less than four pounds, so it’s super easy to carry around. It's even small enough to hold comfortably with one hand—perfect for taking measurements on the go.

Plus, it comes with a carrying case and some handy accessories like calibration solutions and sample cell bottles, which are nice to have when you're testing in different spots.

Also, according to our findings, it's pretty user-friendly. People have found it easy to calibrate and use, even if you're in a moving vehicle, which is pretty cool if you're doing fieldwork.

As for accuracy, its compliance with recognized standards means you can expect consistent and reliable results in various environments. This would make it a practical choice if you need dependable readings for different settings.

If you decide to go for the Sper Scientific 860040, just remember to double-check with the product specs or get in touch with the manufacturer directly if you need to know the exact measurement range. That way, you can be sure it fits your specific needs.
