The Professional Plus is one of the most versatile multi-parameter handheld meters on the market. A combination of up to 11 parameters can be measured on a single bulkhead, including pH, ORP, ammonia, nitrate, chloride, DO, conductivity, salinity, TDS, barometric pressure and temperature, meaning only one cable is required.

• Rubber, over-moulded IP 67 housing (even without battery cover)
• Rugged cable sensors with military specification, waterproof connectors
• USB connection and Data Manager software with GLP functions
• 5000 data sets memory
• Easy to read graphic, backlit display and keypad, and multiple language interface: English, German, French, Spanish, Italian, Portuguese and Norwegian

The Quatro cable/bulkhead allows the measuring of up to six parameters at one time (e.g. conductivity, temperature, dissolved oxygen, 2 mV readings and barometric pressure) and has a combined weight of 525 g.

The sensors are totally interchangeable and easily replaceable by the user, and there are a variety of cable lengths available (1, 4, 10, 20 and 30 m). The Pro Plus can be used with other bulkheads to measure one, two or three parameters at the same time.
