HP-480PL

패널 장착형 pH 미터(4-Wire Transmission, 펄스 비례 제어)

산업용 pH 미터는 펄스 펌프를 직접 구동할 수 있는 펄스 비례 제어 기능이 있는 pH 미터입니다.
pH 센서를 연결하여 시료수의 pH와 온도를 측정 가능합니다.

HP-480PL은 펄스당 주입 분해능이 높기 때문에 pH 값의 미세 제어를 포함하는 처리 시스템의 일부로 펄스 펌프를 제어하는 데 사용할 수 있습니다(예: 미시적 또는 작은 샘플의 pH 값 제어).

측정 범위

pH : 0 ~ 14
온도 : 0 ~ 100 ℃

Pulse proportional control function
A pulse signal proportional to the set pH value is output.
This signal can be input directly into a pulse pump, making it possible to construct a simple system with an excellent cost-performance ratio.
Maximum pulse output of 360 SPM
A maximum of 360 pulses per minute can be output.
It has a high insertion resolution per pulse, allowing for very fine control of pH values.
Compatible with five types of temperature compensation element
Five types of temperature compensation element are supported: 500 Ω, 6.8 kΩ, 1 kΩ, 10 kΩ and 350 Ω.
Easy pH correction
After immersing the pH electrodes in the standard fluid, simply follow the instructions displayed and press the ENT key.
The automatic correction process is plain and simple.
A line-up of lead-free pH electrodes
Uses lead-free glass. In addition, almost all sections of the pH electrodes, including lead wires and soldered junctions are lead-free.
Uses lead-free solder
To reduce the burden on the environment, lead-free solder has been used to mount the components on the printed circuit board.
