920/921/922 Series Precision pH/mV/ORP/oC/oF Meter.
This series include 920, 921 and 922. The meters are used to measure acidity, alkalinity or oxidation-reduction potential of liquids.
Automatic Calibration:
The meters is capable of calibrating up to 3 points using USA or NIST pH standard buffer. From Setup Menu, choose Calibration and immerse pH electrode into indicated calibration solution, 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.
Automatic Electride Slope Display.
After Calibration, if the calibration solution does not match the meter's indicated value, an ERROR message is displayed.
Automatic Temperature Compensation:
Using the supplied temperature probe, the temperature value is displayed on the screen. The meters provides manual or automatic temperature compensation mode for optimum accuracy under variable temperature conditions.
Message Indicator:
The meters displays helpful messages like an on-screen manual for easy operation of this meter and choosing of the various functions and options.
Save And Communication Interface:
This series all have real-time date / clock stamps, The memory stores up to 48 discrete data sets. Press the SAVE to store
the current measured values and it automatically generates a serialnumber with the date and time.
This data can then be sent to a computer via the USB port.
Meters Included:
pH Electrode, pH Standard Buffer, Temperature Probe, Power Adapters, ORP Electrode (Only for 922), Electrode Holder
Features:
::2 points push-button calibration with automatic buffer recognition
::Manual or automatic temperature compensation
::View electrode slope
::Automatic message indicator to help you operate meter
::Expanded memory stores and recalls up to 99 data sets
::Built-in real-time clock stamps for stored data
::USB Communication interface.
