Applications:
1.It is applied to water quality monitoring in petrochemical industry, oil
refining, metallurgy, pharmaceuticals and environmental protection.
Features:
1.It adopts microcontroller for easy use; The plate-type or wall-hung type is
convenient for installation, operation and maintenance.
2. PHG-217D On-line Water Quality Monitor can measure pH value, temperature and ORP of water sample.
3.It can conduct automatic slope calculation and automatic temperature
compensation.
4.It can automatically recognize three buffer solution of 4.00,6.86and 9.18.
5.It has isolation output(4~20)mADC signal, and the output upper limit and lower
limit can be adjusted.
6.It has isolation RS-232or RS-485 (optional) digital signal output.
7.It has automatic upper and lower limit alarming function. Also, it can prevent
data loss in power failure.
8.It can store and view measured data. Up to 400 sets of measuring data can be
stored (including measuring results and storage time).
9. PHG-217D On-line Water Quality Monitor has six control relays. The two of them are used to output
upper and lower limit alarming signal and the other four adopt programmable
controller aiming to combine actuation and release time so that the automatic
cleaning, calibration and other controlling functions can be realized.
10.The electronic unit case has the protection level of IP65 in order to prevent
water spraying and dust pollution.
10.The instrument has two combination modes:
a)PPHG-217D industrial pH/ORP gauge controller (It is suitable for circumstances
