PH- series is an easy-use basic pH meter designed for daily testing and controls are required. This series pH meter includes model PHS-25CW, PHS-3CW and PHS-3BW, it widely used forwater quality research, industry and education applications.
Automatic Calibration:
The meters is capable of calibrating up to 3 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 calibration, if the calibration solution does not match the meter’s
indicated value, an ERROR message is displayed. After calibration, the percentage slope of the electrode is displayed before the meter returns to measurement mode. Per the electrode slopes, you can decides whether to replace the pH electrode.
Automatic or Manual Temperature Compensation:
The meters provides manual or automatic temperature compensation mode for optimum accuracy under variable temperature conditions.
Fluid Resistant Housing and Swivel Electrode Holder:
The integrated plastic housing and keypad is sealed to protect against accidental spills. The electrode holder arm is rapidly switched to both sides and swivels and articulates for convenient use and positioning.
Accessories:
GlasspH Electrode, Temperature Probe (Only for PHS-3BW)
Standard pH Buffers (pH4.01, 7.00, 10.01)
9V/350mAPower Adapters
