Supply of Four Electrode Unidata Conductivity Loggers

The Department of Water, Water Information Branch requires the purchase of 48 (forty eight) four electrode Unidata conductivity loggers only (probes not included, the Department will supply its own) for replacement of existing Unidata toroid conductivity systems that are now 20 years old and are no longer supported by the manufacturer. The department currently operates 145 Unidata four electrode conductivity loggers. Every logger manufacturer supplies its own data logger software that must be used to operate the instrument. The Unidata logger software package (Starlog) is widely used throughout the Department of Water for not only conductivity measurement but also for measuring a wide variety of other environmental parameters.
