Product Description
PHS-3FALaboratory PH Meter
PHS-3FA is a laboratory PH meter with the most powerful functions and the most convenient operation in the
market. It can be widely used for the continuous monitoring of the PH values of the solutions in thermal power
plants, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, foodstuff, running
water, etc.
Features
LCD display, menu and notepad in English.
Computer-based: It adopts high-performance CPU chip, high-precision AD conversion technology and SMT
technology to complete multi-parameter measurement, temperature compensation and instrument self-checking;
it is also featured by high precision and good repeatability. High Reliability: Single board structure, touch button,
no switch knob.
25ºC Conversion: Nernst electrode slope temperature compensation, 25ºC conversion of pure water and
ultra-pure water with addition of ammonia. Input Impedance > 10 12 Ω
Electrode diagnosis: Multi- calibration methods, EO and S queries, monitoring electrode performance
Standard liquid temperature auto-conversion: The temperature curve of the standard liquid is prestored; in
the time of calibration, the standard solution pH at the set temperature is automatically converted.
Network function: RS232 bi-directional communication, which can be equipped with a printer or TLab8.0
Communications and data processing software
Historical data: 3000 data can be stored.
Notepad: 200 messages can be recorded.
Built-in real-time clock: Providing a variety of functional time references.
