Two different options of the HCT63 transmitter will be available with the base model offering a single industry standard 4-20mA output. The Advanced HCT63 will offer two 4-20mA outputs enabling the process temperature to be measured and transmitted as well as either the conductivity or resistivity value. The Advanced HCT63 model will also have 2 relay outputs for process control and also has 3 digital inputs for remote range changing via a plc. Both of the HCT versions are available as head mounted transmitters with purpose built cells which offer cell constants of K=0.01 or 1.0 as well as being...

Specification conductivity sensor Two LTH conductivity cells are available for head-mounting the instrument: CMC64/10/PT43 This has a cell constant of 1.0 and is typically used in wastewater measurement. CMC68/001/PT43 This has a cell constant of 0.01 and is typically used for ultra-pure water measurement. Ranges of measurement 0-0.999 ìS/cm to 0-99.99 mS/cm (K= 0.01 to 1.0) 0-99.99 K.cm to 0-99.99 M.cm (K= 0.01 to 1.0). 0-0.999 ppm to 0-99.99 ppt. (parts per thousand). See the following range/cell constant table. Conductivity accuracy 0.5% of range Linearity 0.1% of range Repeatability 0.1 %...
