C7615 Conductivity controller for panel mounting, range 0 – 20, 0 – 200 or 0 – 2000 µS with two control points and 0 – 20 mA recorder output. Mains supply either 230 or 115 VAC 50 / 60 Hz. Terminations by plug-in connectors for both the sensor, relays and mains supply.C7615- 010 Conductivity controller as above but with ranges 0 – 2, 0 – 20 or 0 – 200 mS. The 7615 series of controllers provide a simple easy to install and use instrumentation and control for many industrial processes. The instruments have bright red digital displays providing easy viewing in poorly-lit conditions and are housed in industry standard 96 x 96 D panel mounting cases.
C7685 Microprocessor Conductivity controller auto ranging up to 0 – 20mS with K = 1.0, use preamplifier with either 4 electrode cell or electrodeless (Torroidal) cell for ranges upto 2000 mS.
Programmable to readout in % concentration for direct reading in acid or caustic strength,
C7685 has two control relays, one alarm relay and an isolated current output, mains supply 115/230 VAC.C7685-010 Special instrument for measuring ultra-pure water with the special temperature compensation for ultra pure water. Able to display in either conductivity or resistivity use with the PSE 001-T Pt100 stainless steel insertion cell. Used in semiconductor and power generation industries.
