Portable pH/mV Meter HI 8424: 马来西亚的首选 ENVIROLAB SDN. BHD.

详情

Features

Waterproof - Compact, heavy duty casing that is protected against any ingress of water that would damage the electronics.
Automatic Calibration - calibration to one or two points to any of the three programmed buffer values (pH 4.01, 7.01, and 10.01).
Automatic Temperature Compensation - Separate temperature probe is supplied to provide temperature compensated measurements.
High Resolution/Accuracy mV Range - The HI8424 automatically switches resolution from 1 mV to 0.1 mV when ORP readings are between -699.9 to +699.9 mV. The accuracy within this range is ±0.2 mV.
Automatic Shutoff - The automatic shutoff feature will turn the meter off after 20 minutes to conserve battery life.
Low Battery Indicator - A low battery indicator will be displayed when the battery life is almost exhausted (5% remaining) alerting the user that a new battery will be needed in the near future.
