Dwyer LLC-118 Conductivity Controller is a versatile temperature and conductivity monitoring solution for electrically conductive fluids. It offers a wide temperature range (-40 to 150°F) and excellent accuracy (±0.25% FS). With a choice of power requirements (120 VAC or 240 VAC), it is adaptable to different environments. The controller can be mounted using an octal or DIN mount, while the probes feature a 3/8" Male NPT fitting. The wetted material is made of durable 316 stainless steel and PTFE. Pressure limit for probes is 400 psig (27 bar). The electrical rating is 10 Amps resistive, 1/3 hp @ 120/240 VAC. It also comes with a SPDT switch type, offering both N.O. and N.C options. The probe length is 72 inches (1.82 m) and features 1/4" (6.3 mm) diameter 316 SS electrodes. The controller sensitivity can be adjusted to either 10K Ω or 26K Ω.
