PHS-W series is an easy-use basic pH meter designed for daily
testing and controls are required.
Automatic Calibration:
The meters is capable of calibrating up to 2 points using USA or
NIST pH standard buffer. Press the CAL key to enter calibration
mode and immerse pH sensor into indicated calibration solutions,
press ENTER key and meter is automatically calibrated.
Auto-Buffer Recognition:
During the calibration, if the calibration solution does not match meter
indicated value, an ERROR indicator will be displayed.
After calibration, the percentage slope of the electrode is displayed
before the meter return to pH measurement mode. Per the electrode
slopes, you can decides whether to replace the sensor.
Automatic or Manual Temperature Compensation:
The meter provides manual or automatic temperature compensation
mode for optimum accuracy under variable temperature conditions.
The integrated plastic housing & keypad is sealed to protect against
accidental spills, The holder arm is rapidly switched to both sides &
swivels and articulates for convenient use and positioning.
