1, Measuring accuracy up to +/-0.002pH. 2, USA or NIST pH Buffer Standards. 3, Fluid Resistant Housing.
High accuracy bench top ph meter
92 series meters includes models 920, 921 and 922, which is a high accuracy meters used for measuring the acidity, alkalinity or oxidation-reduction potential of liquids, its measuring accuracy up to +/-0.002pH.
Feature:
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 pH 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 electrode slopes, you can decide whether to replace the pH electrode.
Choice of USA or NIST pH Buffer Standards
Bante 92 series meters built-in 2 standard pH buffer groups. Through the choice of the Setup Menu, User can set the default standard.
Automatic Temperature Compensation
The meters provides manual or automatic temperature compensation mode for optimum accuracy under variable temperature conditions. Insert the temperature probe into meter, the temperature value will automatically displays on the screen.
Message Indicator
92 series meter have a message indicator, it can shows many helpful messages like an on-screen manual for easy operation.
Communication Interface and Data Store
The meters have real-time date/clock stamps, the memory stores up to 99 data sets. Press SAVE key to store the current measured values and it automatically generates a serial number with time. All of stored data can then be sent to a computer via the USB port.
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.
