This document provides an introduction to the features and usage of the HI2400 microcomputer printer desktop dissolved oxygen meter, including probe connection, power on, measurement operation, calibration, and settings.
The HANNA HI2400 is a desktop dissolved oxygen measuring tool based on electronic processing. It features an LCD display capable of storing up to 99 total records with a capacity of 8,000 sets of readings. The device measures dissolved oxygen in ppm or % and compensates for temperature via an internal ATC circuit. This manual is written in Chinese.
| Dissolved Oxygen Range (ppm) | 0.00~45.00 |
|---|---|
| Temperature Range | -5.0~300.0 |
| Dissolved Oxygen Resolution (ppm) | 0.01 |
| Calibration Points | Single or Dual at 0% and 100% |
| Data Storage Capacity | 99 total, 8000 sets per lot |
The standard calibration procedure involves two points: 0.0% (zero point) and 100.0% (slope).
For accuracy, it requires 20 seconds to stabilize at a correct reading under normal temperature of 25°C.
Yes, the user can switch between ppm and % measurement modes using the RANGE key.
