PHS-W 系列
Benchtop pH/mV meter
PHS-W series is an easy-use basic pH meter designed for daily testing and controls are required.
Automatic Calibration:
The meters are 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 decide 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.
