Spesifikasi pH METER EDUCATION
PH Meter
This instrument also features an extended pH range, dual-level LCD with icons for stability and buffer recognition, built-in magnetic stirrer, automatic pH calibration, and temperature display in either Celsius or Fahrenheit. In addition, all readings are automatically compensated for temperature variations. In the classroom, this compact unit reduces clutter and utilizes a minimal amount of space on the desktop. Switch to battery power and the instrument can be taken outside the classroom for field studies. When lab time is over, the instrument is easily cleaned and can be placed out of the way—right away.
Advantage:
1 Compact and lightweight.
2 Built-in beaker and beaker-top electrode holder.
3 pH and temperature in one probe.
4 Built-in magnetic stirrer.
5 Dual-level LCD.
6 Automatic calibration.
7 Operated by battery or 12 VDC.
8 °C and °F temperature scales.
