Salter Brecknell ESA-300 precision balance is an economical balance ideal for general laboratory, industrial, and educational applications requiring multiple weighing units.  ESA-300 digital scale weighs up to 300 grams in 0.005 gram intervals.  This precision balance features a round, 4.65 inch diameter weighing pan and comes with a draft shield for better performance.

Salter Brecknell ESA balances are equipped with bi-directional RS232 for communicating with a PC.  These balances are portable and operate on 6 AA batteries (not included) as well as an AC Adapter.  Salter ESA-300 balance supports external calibration but requires a calibration mass (sold separately).

Salter ESA series precision balances come standard with an RS232 interface for data communications.  If you purchase an Acculab Vicon or an Ohaus Scout, you are required to pay extra.  Salter Brecknell's economical balances integrate this feature at no additional charge, but again, with Ohaus or Acculab, you have to pay!
