อุปกรณ์วัด pH (Waterproof Portable pH Meter)

HI 9124

Waterproof Portable pH Meter

The HI 9124 is a waterproof pH meter. A large dual-level LCD displays both the pH and temperature along with an operational guide. Graphic symbols are displayed to help the users during the calibration process.

The pH calibration procedure is automatic with five memorized pH buffer values
and buffer recognition to simplify the calibration process.

This meter utilizes the HI 1230B double junction pH electrode. The double junction helps to minimize junction contamination for accurate, consistent results.
