Waterproof pH and Meter - Two buttons for simple operation
- Single probe measures pH and
- Long battery life for extended use
The HI 9210N heavy-duty pH meter is designed to provide laboratory results and accuracy under the harshest of industrial conditions. HI 9210N is supplied with a rugged pH electrode which, in addition to the pH reference system and sensitive bulb, incorporates a temperature sensor and a miniaturized amplifier. You need to use only one probe for both measurements! The electrode signal is also pre-amplified and strengthened to give you better protection against noise and electromagnetic interference, a common phenomenon in industrial applications. Calibration is manual and the trimmers are placed behind a protective cover. This assures that the unit can be calibrated at any pH buffer value. The protective cover also keeps the meter water tight and prevents the calibration from being tampered with. Even though the HI 9210N's battery life is an incredible 2000 hours, a low voltage indicator appears on the screen to alert the user that there is only 20 hours of battery life left. Afterwards, the BEPS (Battery Error Prevention System) will stop any false readings by shutting the meter off.
HI 9210N is supplied complete with HI 1217D gel-filled combination pH/ electrode, and 1 m (3.3') DIN cable, 4 x 1.5V AA batteries and instruction manual.
