HP-960FTP 패널 장착형 pH 미터(4-Wire Transmission, 4 포인트 알람, 시분할 비례 제어)

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-960FTP 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.
Four control outputs equipped
You can set values of your choice for the upper and lower limits of the four control outputs, and switch them to either on-off control or time sharing proportional control.
Automatic diagnosis function for faults in electrode properties
If there is an asymmetry potential, sensitivity or response speed in correction, the HP-960FTP automatically determines whether there is a fault in the pH electrodes, and displays an error message.
Can be linked with a cleaning device via an external input
An input signal from a cleaning device can be used to put the output of the measurement value on hold.
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.
