- Time sharing proportional control function with F Zone
Unlike commonly used time sharing proportional control functions, whose on-off frequency has generally been fixed, the HP-480TP includes an control method called F Zone, whereby as the pH difference becomes smaller, it changes not just the time for which the pump injecting pH regulator is on, but also its frequency.
- Compatible with five types of temperature compensation elements
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.
