Buying Checklist
- Choose 61F-G3 for high-purity water, steam condensate, or other low-conductivity liquids.
- Choose 61F-G or 61F-G2 for ordinary tap water or wastewater instead.
- Choose the electrode holder and probes separately (PS- or F03-series).

FAQ for 61F-G3 AC100-220V
What is the difference between 61F-G3 and 61F-G?
Both are 61F-series floatless controllers on the same AC 100-220 V supply. The G3 is the high-sensitivity grade for high-purity water, steam condensate, and other low-conductivity liquids. The plain G is the standard grade for ordinary tap water and wastewater. Pick the G3 only when the standard G ignores the liquid.
Does the 61F-G3 work with any liquid?
Only with conductive liquids at about 100 µS / cm or higher. Tap water, wastewater, and most process liquids are fine. Oil, fuels, deionized water, and dry chemicals will not be detected. For non-conductive liquids, use a float switch, a capacitive sensor, or an ultrasonic level sensor instead.
What is included in the box?
The controller module only. The 8-pin octal base, the electrode holder, and the stainless-steel probes are sold separately. Common pairings are the PF113A or similar octal base and the PS-31 or F03-05 electrode holder. Order them together with the controller to avoid a second shipment.
