JENWAY 3345 ION ANALYSER
Contact Spectronic on sales@spectronic.co.uk for info on the 3340 which is a lower cost option to the 3345
Dual Display Simultaneous display of primary and secondary measurements. A Switch Screen key is used to toggle 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 3345 Laboratory 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 3345 Laboratory 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 3345 will automatically recognise 2,4,7,9 and 10pH buffers with a manual override facility.
Incremental Methods The Model 3345 Laboratory Ion Meter is programmed to make the calculations necessary when carrying out Known and Sample Addition and Subtraction, and Multiple Sample Addition.
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 3345 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.
A portable instrument, the Model 3205 Portable pH/Ion Meter is also available from Jenway.
