Overview
The HANNA HI8424 is a Portable water quality measuring instrument designed for the measurement of pH, Oxidation-reduction potential (ORP) and temperature. It has the function of simultaneous measurement of pH, ORP and temperature. It is lightweight and easy to carry. It is suitable for water quality monitoring indoors and outdoors. It has automatic temperature compensation and waterproof design to ensure accurate measurement results in different environments.
Features
1. Waterproof design
2. LCD screen display, carrying temperature sensor, automatic temperature compensation function
3. BEPS battery error prevention system, the battery symbol flashes when the battery is lower than 5%
4. Built-in three calibrating points, automatically identify one or two point calibrating
5. Data Reading Stability Display
6. PEI material plastic acidity composite Electrode, suitable for on-site or field harsh environment measurement
7. Easy to operate and cost-effective
8. Choose the right Electrode pairing for different applications
Principle
The HI8424 collects water quality parameters through pH Probe and temperature sensor, and uses automatic temperature compensation to correct pH and ORP Measured values at different temperatures to ensure data accuracy. The instrument is designed with high input Impedance to reduce signal interference and automatically identify the calibrating process with built-in calibrating points.
Applications
Indoor water quality monitoring, outdoor water quality monitoring, field measurement, field environment measurement
Steps
1. Power on the instrument
2. Connect pH Probe and temperature sensor
3. Select the calibrating mode, the instrument automatically recognizes one or two point calibrating
4. Immerse Probe into the solution to be tested
5. Read the pH, ORP, and temperature data displayed on the LCD screen
6. Clean the Probe and turn off the power after use
Notice
• Avoid use outside the ambient temperature range (0 - 50 ° C)
• Replace the battery in time when the battery is lower than 5%
• Probe clean before calibrating
• Pay attention to the use restrictions of waterproof design in humid environment
• If it is not used for a long time, it should automatically shut down to save power.
