GENERAL DESCRIPTION
Analogik PH meter and transmitter incorporates the latest high technological advancements. It has very stability, reproducibility & contineous duly cycle. The instrument having very high input impedance advanced (MOS-FET butter OP-AMP) The instrument accepts all types of PH electrode. Auto / manual temp, compensation facility is available. The instrument indicates PH by 3 1/2 digit LED / LCD display.
FEATURES
Manual / Auto temp, compensation by pt-100 sensor.
Direct indication of PH/ mV and temp, by LED/LCD displays.
Slope control for correcting electrode slope.
Asymetry control to eliminate ageing offect.
0 / 4 to 20 mA output into 500 V incase of PH transmitter.
CONSTRUCTION & OPERATION
The glass epory, green masked, PCB with high quality components soldered gives the drift free performance. The mV signal from PH electrode is directly given to high I / P impedance buffer amplifier and then this signal is processed. The auto/manual temp, compensation circuit is added at this stage & signal is given to DPM / V to I connector.
Thus we get PH indication or 0 / 4 to 20 mA signal proportional to input pH.
APPLICATIONS
pH meter and PH transmitter are commonly used in many industries & plants. Used in water treatment plants, Power Station, Sugar Mills, Steel Plant, Paper Industry, Chemical, Petro Chemical, Food, Fertiliser, Soft Drink Industries.
