220/221 Series
A & E Lab.
Main Products: Atomic Absorption Spectrometer (AAS), Fluorescence Spectrophotometer, Bio-Spectrophotometer, UV Vis Spectrophotometer, Visible Spectrophotometer, Flame Photometer, Whiteness Meter, Turbidity Meter, Colorimeter, Gloss Meter, Tintometer, Automatic Polarimeter, Auto Melting Point Apparatus, Automatic Refractometer, Abbe Refractometer, PH/DDS/TDS Meter, etc.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. After calibration, the percentage slope of the electrode is displayed before the meter returns to measurement mode. Per the slope value, you decides whether to change the pH electrode.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.Hold Function:
To keep the latest measurement on the display, after taking a reading press the HOLD key and the measurement remains on the display, You can easily view and record data.Power Monitor:
During using, The CPU continuously monitors and displays the battery level, When the battery is running out of power, The battery icon will disappear from the LCD.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 50 discrete data sets. Press the SAVE to store the current measured values and it automatically generates a serial number with the date and time. This data can then be sent to a computer via the USB port.
