The Slim48 series HP-480PL industrial pulse proportional control pH meter
HP-480PL
Overview
The HP-480PL industrial pH meter is a pH meter with a pulse proportional control function, which can drive a pulse pump directly.
As the HP-480PL has a high injection resolution per pulse, it can be used to control a pulse pump as part of a system for processing involving fine control of pH values, for example controlling the pH values of microscopic or small samples.
Features
•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.
