Features:
New design, Aluminium shell, Metal texture.
Intelligent: This industrial pH meter adopts high-precision AD conversion and single chip microcomputer
Processing technologies and can be used for the measurement of the PH values and temperature, automatic temperature compensation and self-checking.
Reliability: All the components are arranged on one circuit board. No complicated functional switch, adjusting Knob or potentiometer arranged on this instrument.
Double high impedance input: The latest components are adopted; The impedance of the double high impedance input can reach as high as l0
12Ω . It has strong interference immunity.
Solution grounding: This can eliminate all the disturbance of the ground circuit.
Isolated current output: Optoelectronic isolating technology is adopted. This meter has strong interference
Immunity and the capacity of long-distance transmission.
Communication interface: It can be easily connected to a computer to perform monitoring and communication.
Automatic temperature compensation: It performs automatic temperature compensation when the temperature is within the range of 0~99.9 degree Centigrade.
Water proof and dust-proof design: Its protection grade is IP54. It is applicable for outdoor use.
Display, menu and notepad: It adopts menu operation, which is like that in a computer. It can be easily
Operated only according to the prompts and without guidance of the operation manual.
Multi-parameter display: The PH values, input mV values (or output current values), temperature, time and status can be displayed on the screen at the same time.
