- SM21’s are pH measuring or glass electrodes. G is general purpose glass while L denotes high temperature (130 C). 4 is bulb shape while 6 is Heavy Duty dome shaped glass.
-SR20’s are reference electrodes.
SR20-AP26 has a double junction to slow down poisoning of the element.
SR20-AC22 has pelletized KCl to perform up to 122C
-SC21’s are combination pH/Reference The SC21-AGP26 has Heavy Duty glass and double junction reference.
-SM60’s are temperature RTD’s. SM60-T1 is Pt1000 which is recommended. SM60-T2 for customers that have to have Pt100 for one reason or another.
