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 excellent condition, fully functionaly, easy to calibrate, and includes an instruction manual, 10 feet of probe cable, and DO probe. Calibration/operation instructions are on the reverse side of the meter. It 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).
The meter would be an excellent backup or even primary meter for water quality monitoring programs. YSI meters have been the workhorse of the wastewater treatment industry for years and this meter will likely serve you well either in the field or lab for the foreseeable future. I am asking $400 for the meter and accessories and assume the buyer will pay shipping/insurance. Please reply by e-mail or call me directly if there is an interest. Thank you. Regards, I.
