Features
Digital pH-meter PHS-W is user-friendly and simple tool for routine measurements and water quality control. PHS-W series include 3 models:
Automatic calibration
To provide more precise measurements pH-meter PHS-W has 3-level calibration according to NIST standards (pH 4.00, 6.86, 9.18) and USA (pH 4.01, 7.00, 10.01). Digital pH-meter PHS-W automatically determines and calibrates measurements. For choosing way of calibration press button CAL, then put pH sensor in calibration solution and press ENTER. Then, calibration will be run automatically.
Auto-buffer recognition
In case when calibration solution doesn’t meet displayed values, pH-meter automatically informs about error. After calibration percent value of slope ratio will be displayed, then ph-meter will turns back to measurements. With help of electrode slope coefficient its easy to decide whether to replace pH electrode.
Automatic and manual temperature compensation.
Main feature of Digital pH-meter PHS-W is presence of automatic and manual compensation with precise accuracy in different temperature conditions.
Digital pH-meter PHS-W includes:
- pH-meter
- electrode holder
- standard pH samples (pH4.01 25оC, pH10.01 25оC, pH7.00 25оC), glass electrode
- adaptor
- sensor
