Features
●Stable measurement by DSP (Digital Signal Processor) even with bubbly environment
●Fitting two sensor unit to one main unit
Realizes good space factor and cost effectivity by controlling two sensors in one main unit. Different chemical, different size measurement is possible.
●Good readability by VFD
VFD (Vacuum Fluorescent Display) gives very good readability in limited installation space (HLF820).
HLF820_display
●High temperature chemical resistant
All contacting surface to the measuring liquid is made by chemical resistant NEW PFA. Genuine sel-developed ceramics element realizes the use in high temperature liquid up to 200 deg C (K type).
●Detachable cable enables easy installation
Sensor cable can be detached from the sensor unit, so the installation of the sensor unit is easily done without cable. The cable length can be selected fro 5 or 7 meters. HLFS cable
●PC monitoring is possible by RS-485 communication
