PSC-154: TDS/EC Controller with 4-20mA Output เครื่องวัดค่าความนำไฟฟ้า

New controller includes extended range, digital calibration, on-screen temperature, tri-color display and 4-20mA output.

• Monitors and controls TDS/EC levels for high output commercial systems.
• Large, bright L.E.D. display.
• 4-20mA output signal can connect to a PLC to record values.
• An alarm will sound if the TDS /EC level rises above the user-set level.
• A switch will control a device based upon the set point.
• On-screen temperature display (C/F).
• Installs easily in minutes.
• Includes one sensor probe (at no extra cost) (part #SP-1-PSC).
• Protective cover also available (sold separately)
