CX-LPH--1608A Laboratory PH Meter
CX-LPH-1608A is a PH meter with the most powerful functions and the most convenient operation on the market. In the aspects of the intelligence, the measuring property, the usage environment as well as the external structure, great improvement has been made, so the accuracy of the instruments is very high. It can be widely used for continuous monitoring of PH values of the solutions in thermal power plants, chemical fertilizer, alloy, environmental protection, pharmaceutical, biochemical, foodstuff, running water, etc.
Features:
Double-row nixie tubes display PH value/mV value and temperature respectively.
Computer-based: It adopts high-performance CPU chip, high-precision AD conversion technology and SMT
technology to complete the multi-parameter measurement, temperature compensation and instrument
self-checking, with high precision and good repeatability.
Reliability: Single board structure, touch button, no switch knob
25℃ Conversion: Nernst electrode slope temperature compensation, pure water and ultra-pure water with
addition of ammonia converted at 25℃.
Standard liquid temperature auto-conversion: It pre-stores the temperature curve of the standard liquid; in the
calibration, it can convert pH value of the standard liquid automatically at the set temperature.
Auto-determination of error calibration: If the user wrongly uses the standard buffer solution in the calibration,
the instrument will prompt automatically.
Network function: RS232 bi-directional communication, equipped with a printer or TLab8.0 communications
and data processing software
