产品描述
The PHCL-33 is a versatile instrument that can simulate the millivolt output of a pH electrode in 2 pH increments to test pH meters, recorders and other instruments with a millivolt input level. It can be used to determine which components in a pH measurement system are malfunctioning, and also check the accuracy of manual and automatic temperature compensation networks. To further enhance the PHCL-33’s capabilities, a high/low impedance switch is incorporated to determine if an instrument’s high impedance has been compromised and also allows calibration of lower impedance recorders and meters.
