Hanna ISO Turbidity Portable Meter HI98713-01

The HI98713-01 ISO Turbidity Portable Meter is a high-accuracy, manufacturer-specified portable turbidity meter designed for water quality measurement and compliance testing. It measures turbidity using an ISO 7027–adapted nephelometric method and provides reliable FNU/NTU readings across low and high turbidity ranges for field and laboratory applications such as drinking water monitoring, surface water assessment, treated wastewater verification, and industrial process control.

Key Features:

• Model: HI98713-01 (ISO Turbidity Portable Meter)
• Turbidity range: 0.00–9.99; 10.0–99.9; 100–1000 NTU (FNU)
• Resolution: 0.01 / 0.1 / 1 FNU; Accuracy: ±2% of reading plus 0.1 FNU; Stray light: <0.1 FNU
• Light source / detector: 860 nm IR LED with silicon photocell; ratio nephelometric method (90° & 180°)
• Data & power: USB or RS232 connectivity, 200-record log memory; powered by 4 × 1.5V AA batteries or AC adapter
• Physical: 224 × 87 × 77 mm; weight 512 g; operating environment 0 to 50 °C, RH max 95% non-condensing

Advantages:

• ISO 7027–adapted measurement ensures results aligned with international turbidity standards.
• High sensitivity and low stray light (<0.1 FNU) enable accurate measurement in very low turbidity ranges.
• Portable, battery- or AC-powered design with USB/RS232 and 200-record memory supports field testing and data transfer.
• Multiple-point calibration (two to four points) with supplied AMCO-AEPA-1 standards provides traceable verification and long-term accuracy.
