Another commonly deployed but optional sensor (Turbidity) was quoted at ($1,340; YSI), ($1,525; Hach-Hydrolab), and ($1,431; In-Situ).
Always confirm and spec out the components, hardware/software and supplies you will need/prefer to meet the monitoring conditions you anticipate, before negotiating best price possible. There may be additional ancillary components you want to consider (battery chargers, various interface cables for laptop, extra/backup sensors etc.)
Some common additional sensors (depending on sonde type/vendor) that may be utilized (DQO dependent) are Turbidity, Chlorophyll a, Blue-Green Algae, Rhodamine WT, Ammonia/Ammonium, Nitrate, Chloride, ORP/Redox, Ambient Light - PAR, Total Dissolved Gas, (Salinity/TDS, like Sp.Cond. are calc. from raw conductivity using the manufacturer's built in algorithms).
