Meets EPA Method 180.1

• Single-standard RapidCalTM calibration offers the simplest solution for low-level measurements.
• Single-step verification and on-screen assisted calibration eliminates the need to reference complicated manuals.
• Exclusive algorithm in the Rapidly Settling TurbidityTM mode provides accurate, repeatable measurements for rapidly settling, difficult-to-measure samples while eliminating the need for redundant measurements and estimating.
Hach portable turbidimeters are supplied with four AA alkaline batteries, a carrying case with insert, StablCal primary calibration standards in 1" sealed vials ( 20, 100, 800 NTU) , a 10 NTU primary verification standard, 6 sample cells with screw-tops, instrument manual ( printed and on CD-ROM) , quick start guide, silicone oil and oiling cloth.
