PHG-206 aquarium ph meter
PHG-206 Intelligent On-line PH Meter is one of the intelligent on-line chemical analyzers of the PH series developed by out company. With strong environmental adaptability, clear display, easy operation and excellent measuring performance, the PHG-206 intelligent On-line PH Meter has very high performance-price ratio. It can be widely used for measuring the PH and temperature values of the solutions used in the following industries: thermal power plants, chemical industry, chemical fertilizer, metallurgy, environmental protection, pharmacy manufacturing, biochemistry, food and running water etc.
Features
Intelligent: This intelligent online PH meter adopts high-accuracy AD conversion and single chip microcomputer |
processing technologies and can be used for measuring the PH values and temperature. This meter has many |
functions such as automatic temperature compensation. |
Strong interference immunity: It adopts the latest components and high-impedance input of l012Ω. Its current |
output adopts optoelectronic isolating technology. This meter has strong interference immunity and the capacity |
of long-distance transmission as well as excellent electromagnetic compatibility. |
High protection grade: It adopts waterproof and dust-proof design and is applicable for outdoor use. (With a |
protection grade of IP65) |
25°C Conversion: For pure water and ultrapure water added with ammonia, the PH value measured at a temperature other than 25°C is converted to that at 25°C, which is regarded as the reference temperature; |
thus, this PH meter always displays the PH values at 25°C. Therefore, this meter is especially suitable for testing |
the various water solutions in power plants. |
Multi-parameter display: The PH and temperature values can be displayed on the screen at the same time. It |
adopts LED display module with high brightness. The main display can show the pH values with red 10 x 10mm |
Nixie tubes. As red display is eye-catching, the displayed values can be seen from a long distance away. |
Communication interface: It can be easily connected to a computer to perform monitoring and communication. |
