Industrial 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.
