In-line or submersible electrodes with probe guard operate from 23 to 176°>F (-5 to 80°>C) and have a PVC housing with a 3/4'' NPT(M) fitting on both ends. Epoxy body withstands pressures to 100 psi. Measure pH from 0 to 14. All electrodes measure 6-3/4''L x 1'' OD, with a 1-3/4'' insertion depth.

Note: 100Ω RTD ATC elements are platinum and conform to DIN curve 43760. ATC connector is miniature audio plug.
Connector for the 1 kΩ RTD and the 3 kΩ Balco ATC elements is a spade lug.
Connector for 100 kΩ thermistor ATC elements is a standard 1/4" phone plug.
