HI8417, HI8519, HI8520, and HI8521 are bench-top pH meters from Hanna Instruments, designed for simplicity and ease of use.
This document provides instructions for the use of four Hanna Instruments bench-top pH meter models: HI8417, HI8519, HI8520, and HI8521. The manual details the functional descriptions and specifications for each model, noting that most are microprocessor-based with automatic or manual temperature compensation capabilities.
| Range pH | 0.00 to 14.00 |
|---|---|
| Resolution pH | 0.01 |
| Accuracy pH | +0.01 (at 20°C / 68°F) |
| Temperature Range | -10.0 to 125.0 °C |
| Recorder Output | 0 to 2 Volts |
The HI8417 automatically recognizes six standard calibration buffer values: three each for NBS (pH 4.01, 6.86, 9.18) and technical standard calibration buffers (pH 4.01, 7.01, 10.01).
The battery lasts approximately one month when fully charged and is automatically charged whenever the meter is plugged in.
The dimensions are 230L x 170W x 10H mm (9.1x6.7x2.7 inches).
