Product Description

                          PHG-206 Industrial Water Treatment PH Meter
    PHG-206 Intelligent On-line PH Meter is one of the intelligent on-line chemical analyzers of the PHG series developed by out company. With strong environmental adaptability, clear display, easy operation and excellent measuring performance, it has very high performance-price ratio and can precision measuring the PH and temperature values of the solutions. It can be widely 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)
25ºC Conversion: For pure water and ultrapure water added with ammonia, the PH value measured at a temperature other than 25ºC is converted to that at 25ºC, which is regarded as the reference temperature;thus, this PH meter always displays the PH values at 25ºC. 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.
