KERN EW-N EG-N Precision Weight Scale
The KERN EW-N and EG-N precision weight scale line is the best choice for simple weighing tasks. Reliable and easy to use, this laboratory balance provides you with accurate measurement results and a long service life.
Feature rich yet economical precision weight scale. A great laboratory balance.
Features
- Internal calibration, EG-N. External calibration, EW-N.
- Precise piece counting. Reference optimization gradually improves the average value of the piece weighing. Reference quantities of 10, 30, 50, 100 pieces
- GLP/ISO record keeping when used with statistical printer
- RS232 data interface
- Draft shield standard for all models with weighing plate size B. Removable cover with opening for using a pipette. Weighing space WxDxH 158x130x78 mm.
- Weighing with tolerance range (check-weighing). Input of one upper and lower limit value is possible in grams, pieces or %. A visual signal on the display assists dispensing or grading. Balance displays value over or under limits.
- Displays deviation from reference weight in %
- Capacity display. An ascending bar graph displays the remaining available weighing range
- Suspended weighing with hook on underside of balance
- Protective working cover over keyboard and housing
- Can be switched to non-metric units at the touch of a key.
- Permitted environmental temperature +10 to +30 °C.
- 3-year warranty
Options
- Internal rechargeable battery pack, operating time approx. 32 h, charging time approx. 12 h. Selectable AUTO-OFF after 3 min without change of load to preserve battery.
- Loop for suspended weighing
- Glass draft shield with 3 sliding doors, left right and top, weighing space WxDxH 150x140x130 mm, for all models with weighing plate B
- DKD calibration certificate available
