The Model 3330 Laboratory PH/Ion Meter |
|
Dual Display Simultaneous display of
primary and secondary measurements. A Switch Screen key is used to toggles
the input channel priority. Ease of Use A simple push-button control panel, used in conjunction with the display, ensures that even inexperienced operators can achieve reliable results. Dual Input (Rear Panel) The Model 3330 Laboratory PH/Ion Meter features two independent input channels for both sensor and temperature monitoring. A socket is provided for connection to an optional overhead or bench stirrer which can then be controlled directly from the instrument keypad. Set Up Menus Set-up menus are provided on the Model 3330 Laboratory PH/Ion Meter to give access to all user defined options. |
Languages Clear user instructions are available in six language
options, (English, French, German, Italian, Portuguese or Spanish),
operator selectable via the instrument set up mode.
Calibration A choice of 1 to 3 point calibration is offered for pH
measurement and 1 to 5 point calibration in Ion mode. The Model 3330 will
automatically recognize 2, 4, 7, 9 and 10pH buffers with a manual override
facility.
Sample Measurement Icons and prompts guide the user through
calibration and measurement routines.
GLP Essential to the modern laboratory GLP protocols are fully
supported. Product performance is continually monitored, with all logged
results being time and date stamped, thus satisfying the requirements of
Good Laboratory Practice.
RS232 / Analog Outputs The Model 3330 Laboratory PH/Ion Meter can
download directly to a computer or printer by the bi-directional RS232
link and provides an analogue output for connection to a chart recorder or
datalogger.
Other Ion Meters available from Techne® are the Model 3205 Portable Ion Meter and the Model 3345 Laboratory Ion Meter.
