INTRODUCTION
Congratulations on your purchase of WT-80 pH/ORP meter. A convenient
instrument to measure water pH/ temperature and ORP value.
Features
• Automatic buffer recognition to avoid pH calibration error.
• Hold function to freeze the record.
• Max./Min. review of memorized data.
• Backlight for dark environment operation.
• Easy to view pH probe calibration data.
• USB connection for data download to a PC
• pH electrode with automatic temperature compensation.
• Auto power off to save battery power
OPERATION
Starting Up
1. Install batteries or connect with an adaptor to the power socket.
2. Connect pH or ORP electrode to the BNC port on the top of the meter.
While using pH probe, please also connect the temperature sensor plug
to the socket next to BNC.
3. Available parameters for two probes are:
pH probe:
pH value, mV value & Temperature.
OPR probe:
mV value
NOTE:
pH unit for ORP probe is meaningless
pH Probe-pH/mV Measurement
This meter is designed to take reading with automatic or manual temperature
compensation. Automatic temperature compensation only occurs when the
temp.sensor is plugged. For manual temperature compensation, the default
setting is 25ºC / 77ºF. You can manually adjust the temperature.
Be sure to remove the pH electrode soaker bottle before measurement. To
take the readings:
1. Rinse the probe with de-ionized or distilled water before use to remove
any impurities adhering to the probe. If the electrode is dehydrated,
soak it for 30 minutes in KCl solution.
