Wiggens pH Meter


The WalkLAB Professional pH Meter pH90 is a portable yet highly accurate pH meter. It is used in all industries as well as commercial and educational teaching aids.
The meter uses a regular BNC connector and accepts a variety of other electrodes for special measurement needs. The meter comes complete in a hard carrying case with calibration buffer solutions.
Advanced Features:

Large LCD with Multiple Display
Display of pH, temperature and time simultaneously

Autolock Measurement
Meter automatically sense a stabilized endpoint reading
This ensures workers only takes in an accurate reading
all the time and every time.

Multi-point calibration
Automatic buffer recognition with built-in standards:
ISO – pH7.00, 4.01, 10.01
NIST – pH6.68, 4.01, 9.18
Custom – Manual set to any buffer standard.
Up to 5 points calibration

Electrode status indicator
Able to display the percentage of the slope of the electrode after successive calibration. This feature enables the user
to determine if the electrode should be replaced due to wear and tear.

Real-Time Memory
Able to save records of up to 99 data memory with date and time, enable download to PC.

Online PC link
Able to link to a PC for online display with optional PC kit (sold separately) and download saved data.
Meter uses regular AAA size batteries and taps power source from PC when connected via the USB cable.
