Automatic Temperature Compensation many modern pH controllers also read solution temperature and have auto temperature compensation fitted as standard.

We are able to supply pH electrodes with built in ATC and we are also able to supply separate stainless steel auto temperature compensators.

These can be specially sized and have a special temperature sensor inside to suit the instrument in use. Great care must be taken to ensure the correct specification temperature sensor is used. Many large manufacturers use obscure values of ATC fitted inside their electrodes to try to prevent the use of alternative electrodes.

ATP100-10ST Stainless steel automatic temperature compensator temperature range 0 - 100oC mounting by 1/4” BSP male thread, length 100 mm cable length 3m many other variations can be made please ask us.

pH Transmitter Range

Within our pH Transmitter range we offer the P3630 pH Transmitter. This instrument is one of our top selling instruments and offers an excellent way of transmitting a pH signal to a PLC or other device. 

The unit is normally located within close proximity to a pH electrode giving the operator a visual indication of the current pH output. The pH Transmitter then transmits the pH value using a 4-20mA (or 0 - 20mA) current signal to a PLC or Chart Recorder which can be located up to 1000 metres away. The same 2 wires which transmit the pH signal as a 4-20mA current signal are also used to power the pH transmitter. This "loop powered" system ensures an efficient transfer of the signal and means that the pH transmitter can be housed in either a small din rail mounting enclosure or as a surface mounted pH transmitter system.
