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.




pHTestr 10 Calibration


The waterproof pH Tester model:- pHTestr10 has a simple push button 3 point calibration mode. This reduces the time needed to buffer the unit to allow for the quick measurement of pH values. By using the a 3 point calibration the pHTestr 10 offers precision readings across the logarithmic pH scale while also being housed in an IP67 Rated Waterproof enclosure. 

The calibration process is simple using pHBS4, pHBS7 and pHBS10 from our pH buffer solution range to give a representative sample across the pH scale. 

Having rinsed the instrument in water (not de-ionised water) simply insert the pHTestr10 into the first buffer solution, turn the unit on and hold the calibration button down. The instrument will identify which buffer solution, adjust it's internal value accordingly, also give you the previous reading for when the unit was last calibrated. Rinse the electrode again in water and repeat the process for the remaining buffer solutions.

Model:- pHWPSEN

Replacement Electrode For pHTesr10

The pHWPSEN is the Replacement electrode for the pHTestr10. The pHWPSEN comprises of a double junction pH Electrode with built in Automatic Temperature Compensation. 

To replace the electrode in the pHTestr10, the old electrode simply twists off the unit and the replacement pH electrode slots into place and the holding collar is tightened to secure it.
