PHG-217D Industrial pH/ORP Measurement ControllerDetailed product description：

PHG-217D Industrial pH/ORP Measurement Controller

Instrument features:
The display mode is backlit dot matrix, using a Chinese menu, and simultaneously displaying the pH value and temperature value or ORP value and temperature value of the tested water sample
It has a (4-20) mA DC isolated output signal, and its output upper and lower limits can be set arbitrarily
Equipped with upper and lower limit alarm functions, with a contact capacity of 2A and 220V AC (non inductive)
Equipped with power-off data protection function, even if there is an abnormal power outage, the data stored inside the instrument is still valid. After restarting, it can enter the measurement without calibration
The instrument has the function of automatically identifying three standard solutions: 4.00, 6.86, and 9.18
Equipped with automatic slope calculation, automatic temperature compensation, automatic calibration, and automatic cleaning functions
The protection level of the electronic unit chassis shell is IP65, which can prevent water spray and dust intrusion
Equipped with RS232 or RS485 output interfaces, it can achieve digital output

There are two ways to combine instruments:
a) PHG-217D (suitable for situations where the distance between the measuring point and the instrument is far, up to 20 meters)
b) PHG-217D-1 (with preamplifier inside the instrument) can be directly connected to the transmitter (suitable for measuring points within 5 meters of the instrument)

Supporting transmitters: PHGF-27, 27B28, 28B, 29, 30, 31, 32, 33, 35 (all 2001 versions)
PHGF-43、PHGF-46
Note: If there are special requirements (such as high temperatures greater than 60 ℃ and special media, a transmitter can be customized and suitable electrodes can be selected)
