I have a used YSI Model 50B DO meter for sale. The meter has a microprocessor with a digital readout and was designed for field or laboratory use. It is in good to excellent condition, fully functional, easy to calibrate, and includes an instruction manual. Unfortunately, = it does not include a probe/cable set; however, I understand that a = replacement probe (YSI 5739 Field Probe) and cable (YSI 5740-series of various = lengths) are readily available via YSI Incorporated. Calibration/operation instructions are on the reverse side of the meter. The meter includes automatic temperature correction and operation from either a power cable (available via YSI) or batteries (6 D cells typically provide ~1,000 = hours of use).
=20 As you are likely aware, YSI meters have been used by at wastewater treatment facilities for years and this meter will likely serve you well either in the field or lab for the foreseeable future. This meter would = be an excellent backup or even primary meter for supporting water quality monitoring programs. =20 =20 I am asking $250 for the meter and assume the buyer will pay shipping/insurance.
