MULTI-PARAMETER WATER QUALITY TESTER
The PH-2398 multi-parameter water quality tester measures pH, electrical conductivity (EC), oxidation-reduction potential (ORP), and temperature. A large backlit LCD presents readings clearly, while automatic temperature compensation is available for pH and EC measurements. The instrument also supports automatic calibration and stores up to 50 measurement records.
Built-in Bluetooth supports data collection and monitoring through a computer or Android phone. The PH-2398 is designed for users who need several water-quality measurements in one instrument, with configuration options for different ORP measurement needs.
| Four Parameters | One instrument measures pH, EC, ORP, and temperature |
| Display | Large backlit LCD for clear readings |
| Temperature Compensation | Automatic temperature compensation for pH and EC |
| Calibration | Automatic calibration for convenient setup |
| Bluetooth | Built-in Bluetooth connection to a computer or Android phone for data collection and monitoring |
| Data Storage | Stores up to 50 measurement records |
| Optional FCL | Optional free chlorine (FCL) function is available |
The large backlit LCD shows the active parameter and its reading. The control panel carries the mode and calibration keys, marked with the pH 4.00 and pH 6.86 calibration points, and the instrument floats upright so readings can be taken while it stays in the water.

Measurement selection: select the pH, temperature, ORP, or EC measurement mode.
Data logging: manually save readings and review up to 50 stored records.
Bluetooth data transfer: connect to a computer or Android phone for data collection and monitoring.
Automatic calibration: the instrument supports automatic calibration using the specified pH and EC calibration solutions.
The source describes the tester as sealed and waterproof but does not provide an IP rating. Keep the charging-port cover firmly closed after charging. When replacing an electrode, seat the waterproof gasket correctly and tighten the electrode to help prevent water ingress.
Free chlorine (FCL) measurement can be added as an optional function. Confirm the FCL probe and measurement specifications for the selected configuration.
